5. How to create an inbound interface using Asynchronous mode with SkyvvaSalesforce Adapter

Overview

This document explains how to create a SKYVVA Inbound Interface in Salesforce that processes incoming record sets through Asynchronous mode — the SkyvvaSalesforce receiver channel's Mode = Asynchronous setting. The adapter sends the whole request to Salesforce in a single call. Salesforce creates one or more IMessage__c records for the payload — one root message plus one child message per node in the hierarchical tree — and, depending on how the interface itself is configured (§1.3), either processes them into Account/Contact records immediately or hands the work to a background job and returns a JobId you can track.

Note: Mode = Asynchronous is not the same thing as Processing Mode = Asynchronous on the
interface record — the two fields share a name but control different things. The CPI channel's
Mode value is what actually selects this processing path; the interface's own Processing Mode
field is set to Asynchronous here mainly for consistency with the other tutorials in this
series, not because it's what drives dispatch through this channel.

It covers the following steps:

1. Create and configure a SKYVVA Inbound Interface in Salesforce, including the field that controls how the request is processed.
2. Create an integration flow in SAP CPI.
3. Configure the HTTPS sender channel.
4. Configure the SKYVVA Salesforce receiver channel with Skyvva API Version = V3 and Mode = Asynchronous.
5. Deploy the integration flow.
6. Send a test request from Postman through SAP CPI.
7. Monitor the message in SAP CPI.
8. Verify the resulting records in Salesforce.

Context Before You Start

In short: Asynchronous mode sends the whole request to Salesforce in one call. Salesforce creates the IMessage__c record(s) for it — one root message plus one child message per node in the hierarchical tree — and then decides how to turn them into Account/Contact records based on the interface's own Inbound Processing Behavior field (§1.3): left blank, it queues a background job and returns a JobId right away, before the records are actually created. Set to Create Message Only, the messages are created and left for separate processing instead.

Reasons to pick this path:

• You want the request itself tracked as its own visible record (IMessage__c) — useful for

• Nothing extra to configure beyond the one field in §1.3 — this is the simplest of the four V3

Good fit for:

• Moderate-volume inbound traffic where per-request traceability matters more than raw throughput.
• Hierarchical (parent-child) payloads too — this tutorial uses the same Account-with-nested-Contact

Note: There is no package-size setting for this mode with the default interface
configuration — the whole payload is sent through as one call, and Salesforce processes it as one
unit in the background. See §1.3 for the one case where a package-size field does apply.

End-to-end sequence: the steps below — create and configure the Interface (including the field that controls processing behavior) in Salesforce, build the CPI iFlow (HTTPS sender → SkyvvaSalesforce receiver with Mode = Asynchronous), deploy, send a test payload from Postman, then confirm the resulting records in Salesforce.

1. Salesforce Interface Development

1.1 Create the Interface

Create a SKYVVA Inbound Interface under Integration in Salesforce (create the parent Integration record first if you don't already have one).

For this example, create the interface AccountContactAsync_IN. Leave the Message Type field blank. For a V3 Inbound interface, leaving Message Type unset is what triggers Hierarchical Mapping — there is no MetaData Provider/Repository/Message Type hierarchy to build first; the Mapping Tool derives the parent/child tree directly from Salesforce's own schema instead.

Configure the interface:

This is the main interface's own Inbound Setup section — with External Mapping enabled, set Salesforce External ID = skyvvasolutions__ERP_DEBTOR_ID__c, the Account-level external key used to match/upsert Account records:

Figure 3: Main interface AccountContactAsync_IN — Inbound Setup, External Mapping enabled with Salesforce External ID skyvvasolutions__ERP_DEBTOR_ID__c (Account).

1.2 Map Account → Contact in the Hierarchical Mapping Tool

Open the interface's Mapping Tool (Interface detail page → Open Mapping). Because Message Type is blank on a V3 Inbound interface, the Source tree is built live from the Account object's own schema rather than from a predefined Message Type — including its child relationships. Expand the tree down to the Contact(AccountId) child-relationship node to reach it.

With External Mapping enabled on the interface (§1.1), field-level mapping is not needed — External Mapping auto-maps fields by name on its own. All this step has to do is drag the two relationship nodes, top-down, to generate the chained sub-interface:

1. Drag the Account root node onto the target Account root first. This is required, not optional — the target tree doesn't display a Contact(AccountId) node at all until Account itself has been mapped. Expanding the target Account node beforehand shows only Account's other child relationship nodes (no individual fields are ever listed here — with External Mapping enabled, the tree doesn't expose fields for manual dragging at all), never Contact(AccountId), so there is nothing to drag the child relationship onto until the root mapping is done.
2. Expand Contact(AccountId) and drag it onto the target Contact(AccountId) node. No individual field needs to be dragged in either step — this is a node-to-node mapping, not a field-to-field one.

Important — this step is not optional and cannot be replaced by External Mapping alone.
Dragging the Contact(AccountId) node auto-creates a chained sub-interface behind the scenes
(internal, engine-managed — you don't create or configure it yourself), and that's the actual
mechanism that makes the Account+Contact hierarchy work at runtime. External Mapping only
flat-maps fields on an interface that already exists; it doesn't create this chained structure
or walk into child relationships on its own. Skip this step, and posting nested Contact data
will not produce Contact records, no matter how the payload is shaped.

Figure 4: Hierarchical Mapping Tool — Account → Contact(AccountId) node mapping, External Mapping handles field-level mapping.

Save the mapping. Doing so auto-generates the chained sub-interface for the child Contact object mentioned in the note above. That sub-interface has its own, separate Inbound Setup, with its own External Mapping keyed on the Contact-level external ID — skyvvasolutions__ERP_CONTACT_ID__c, not the Account-level ERP_DEBTOR_ID__c used on the main interface (§1.1). Don't confuse the two: they identify different objects, and the sub-interface's External Mapping has to be checked here independently — it is not inherited from the main interface just because External Mapping is enabled there.

Figure 5: Auto-generated sub-interface (Contact) — Inbound Setup, External Mapping enabled with Salesforce External ID skyvvasolutions__ERP_CONTACT_ID__c (Contact).

1.3 Configure Processing Behavior

In the Basket Setting section of the interface, set the field that controls how this request is processed once the messages are created:

Note: Processing Package Size only matters if you set Inbound Processing Behavior to
Batch Apex specifically — in that one case it controls how many records are processed per batch
execution. With Inbound Processing Behavior left blank (this tutorial's setting), the whole
request is processed as a single unit in the background, and this field has no effect.

Figure 6: Interface Basket Setting — Inbound Processing Behavior.

After completing the configuration and mapping in Skyvva, save the interface.

2. SAP CPI Development

2.1 Create the Integration Flow

Create the package in SAP CPI under Design and add the integration flow.

Example:

Figure 7: Integration flow for the Asynchronous mode example.

Important: the Message Mapping step may show a warning icon. Hovering it reveals:
"Http Sender Component may not pass XML or JSON message to Message Mapping. Message Mapping
supports XML or JSON input only." This is CPI's design-time validator flagging that it can't
statically prove the HTTPS Sender's output is XML/JSON — the standard HTTPS Sender adapter has
no fixed content-type contract, so CPI can't guarantee it at design time. It's not about
incomplete field mapping, and it doesn't block deployment: this exact flow deploys and runs
successfully despite it. Safe to leave as-is as long as callers actually send XML/JSON matching
Request Format, as this tutorial's Postman example does.

Where the target schema comes from: export it via the Interface record's Generate MetaData button — Format = XSD Schema, API = V3/Integrate. Then, inside the Message Mapping step's own editor (double-click it on the iFlow canvas), go to the Target panel → Select → Add → upload the downloaded .xsd → pick its root element as the Target Message Type. The file is stored as a resource on this specific integration flow, not somewhere interface/adapter-level or CPI-wide — any other iFlow needing it has to import its own copy.

Note: this interface uses External Mapping with Message Type left blank, so the exported
schema comes from a live object describe rather than a curated tree — confirm it reflects the
nested Account → Contact structure before relying on it.

2.2 Configure the HTTPS Sender Channel

Select the standard SAP HTTPS sender adapter.

General tab: Direction Sender, Adapter Type HTTPS, Transport Protocol HTTPS, Message Protocol None — fixed values, identical in every tutorial that uses this sender.

Connection tab:

Important: The configured User Role must already exist and be assigned to the CPI user/credential that Postman authenticates as, or the sender rejects the request with 403 Forbidden.

Figure 8: HTTPS sender channel — Connection tab.

2.3 Configure the SkyvvaSalesforce Receiver Channel

Select SkyvvaSalesforce as the receiver adapter. The receiver channel has three tabs: General, Connection, Skyvva.

General tab: Direction Receiver, Adapter Type SkyvvaSalesforce, Transport Protocol https, Message Protocol skyvva — fixed values, identical for every SkyvvaSalesforce receiver channel.

2.3.1 Connection Tab

Note: There is no separate "Client Id"/"Client Secret" pair on the current adapter — both are held inside the single Client Credential OAuth2 artifact deployed in the CPI keystore. For the full field reference see 1. SKYVVA CPI Salesforce Receiver Adapter in SAP Cloud Integration.md §3.

2.3.2 Skyvva Tab — Request Settings

Note: Processing Behavior on this channel has no effect on this mode — the field that
actually controls processing is the interface's own Inbound Processing Behavior (§1.3). Leave
Processing Behavior at its default here.

Figure 9: SkyvvaSalesforce receiver channel — Skyvva tab, Mode = Asynchronous.

2.4 Get the SAP CPI Endpoint URL

Go to CPI → Monitoring → Manage Integration Content, locate the deployed integration flow, and copy its endpoint URL.

Figure 11: Manage Integration Content — endpoint URL.

Note: The endpoint URL shape depends on the tenant generation — Neo tenants use
https://{{TenantId}}-iflmap.hcisbp.<region>.hana.ondemand.com/http/<Address>, current SAP BTP
Integration Suite (Cloud Foundry) tenants use
https://{{TenantId}}.<runtime-cluster>.cfapps.<region>.hana.ondemand.com/http/<Address>.
Always copy the exact URL from your own tenant's Manage Integration Content panel rather than
assembling it by hand.

3. Testing with Postman

Use the endpoint URL from step 2.4.

Create a new request with the following configuration:

Request Format = XML

configure the header as:

Content-Type: application/xml

Note: For a small test payload, use Postman's raw body mode and paste the XML directly
— the dropdown next to raw (Text/JSON/XML/…) sets the Content-Type header for you
automatically. For a large payload, pasting that much text into the raw editor isn't practical;
use Body → binary instead, select the XML file from disk, and set the
Content-Type: application/xml header yourself on the Headers tab — binary mode has no type
dropdown of its own, so nothing sets it for you. The file content sent is identical either way;
only how you attach it to the request differs.

Because this interface's hierarchical shape (Account with nested Contact records, external IDs skyvvasolutions__ERP_DEBTOR_ID__c/skyvvasolutions__ERP_CONTACT_ID__c) is the same shape used in the Bulk, Auto-Switch, and Batch tutorials, the same sample payload works here too — the only difference is which interface it's addressed to, resolved on the CPI side via the receiver channel's Interface field (§2.3.2), not from anything in the body itself:

<?xml version="1.0" encoding="UTF-8"?>
<Accounts>
  <Account>
    <skyvvasolutions__ERP_DEBTOR_ID__c>ACC-000001</skyvvasolutions__ERP_DEBTOR_ID__c>
    <Name>CPI Test Account 1</Name>
    <Phone>+49-89-2867825</Phone>
    <BillingStreet>CPI Test Street</BillingStreet>
    <BillingCity>Frankfurt</BillingCity>
    <BillingPostalCode>42098</BillingPostalCode>
    <BillingCountry>DE</BillingCountry>
    <Contact>
      <skyvvasolutions__ERP_CONTACT_ID__c>ACC-000001-C01</skyvvasolutions__ERP_CONTACT_ID__c>
      <FirstName>Max</FirstName>
      <LastName>Mueller</LastName>
      <Email>max.mueller.1.1@example.com</Email>
      <Phone>+49-89-2719583</Phone>
    </Contact>
    <!-- ... more Contact elements for this Account ... -->
  </Account>
  <!-- ... more Account elements, same shape ... -->
</Accounts>

With Inbound Processing Behavior left blank (§1.3), a successful call returns a response listing the message(s) this request created, with a JobId you can use to track the background job. Captured below testing this tutorial with 150 Account records, each with 10 nested Contact records, sent via Body → binary:

Figure 12: POSTMAN request (150 Accounts × 10 Contacts, binary body) and response.

<?xml version="1.0" encoding="UTF-8"?>
<ns0:Response xmlns:ns0="http://soap.sforce.com/schemas/class/skyvvasolutions/IServices">
  <StatusCode>OK</StatusCode>
  <StatusMsg>Successful</StatusMsg>
  <JobId>7079K00001jbgycQAA</JobId>
  <Completed/>
  <PartialCompleted/>
  <Pending/>
  <New>
    <Message>
      <MessageId>a0T9K000000qEMBUA3</MessageId>
      <MessageStatus>New</MessageStatus>
      <SalesforceId/>
      <ExtValue/>
      <MessageComment/>
    </Message>
    <ListOfContact>
      <Message><MessageId>a0T9K000000qEMCUA3</MessageId><MessageStatus>New</MessageStatus><SalesforceId/><ExtValue/><MessageComment/></Message>
      <!-- ... one Message element per created record ... -->
    </ListOfContact>
    <!-- ... one such group per created IMessage__c record (root + hierarchical children) ... -->
  </New>
</ns0:Response>

JobId identifies the background job the messages were queued under; every message is still listed under <New> because the HTTP response returns as soon as the job is queued, before it has actually run. Confirm the real outcome in SAP CPI → Monitor Message Processing (§4.1) and Salesforce → Message Monitoring (§4.2) rather than relying on the response body alone.

4. Monitoring

4.1 SAP CPI

Go to CPI → Monitor → Monitor Message Processing and verify the message completed successfully.

Figure 13: CPI Monitor Message Processing.

4.2 Salesforce

Go to Salesforce → Message Monitoring to confirm the message and resulting Account/Contact records.

Unlike Batch and Bulk mode, Asynchronous mode doesn't queue a basket in the Batch Control Board or Bulk Control Board at all — the underlying IMessage__c record(s) are created right away, and Salesforce processes them via the background job described above. This tutorial doesn't trace a dedicated Salesforce-side UI specifically for browsing IMessage__c records beyond Message Monitoring — if your org has one, use it, but its existence isn't verified here.

Figure 14: Salesforce Message Monitoring — processed message.

After confirming the message, verify that the Account and Contact records were created or updated successfully.
