3614521 - Inbound Service is Blank in Communication Arrangement Created using Custom Communication Scenario

A custom communication scenario is created to call the custom API. However, when creating the corresponding communication arrangement to call the API, the 'Inbound Service' appears blank.

SAP S/4HANA Cloud Public Edition

1. Open the Communication Arrangement app.
2. Create the communication arrangement using the custom communication scenario.
3. Navigate to the Inbound Services tab.
4. Observe that the Inbound Services section is blank.

The external API scenario based custom CDS view is not included as an 'Inbound Service' in the custom communication scenario, which leads to the 'Inbound Service' appearing blank in the communication arrangement. 

To resolve the issue, add the external API scenario based custom CDS view to the 'Inbound Services' section of the custom communication scenario by following these steps:

1. Open the Custom Communication Scenarios app.
2. Search for the custom communication scenario (e.g., YY1_XX_API).
3. Click on Edit.
4. Navigate to the 'Inbound Services' tab and click Add.
5. Select the custom CDS view created with the external API scenario.
6. Click Save to apply the changes.
