2819591 - "Mandatory value missing" message – Integration Center (Inbound)

This behavior is driven by OData API metadata for the target entity/field. Fields marked as required OR not nullable in metadata cannot be NULL or blank, and this configuration cannot be changed in Integration Center.

Scenario 1 – Warning (job completes)

A warning is shown, but the job still completes.

• The target field is not required and not nullable in OData metadata: Required = FALSE & Nullable = FALSE
• Meaning: The field must contain a value (cannot be NULL/blank).
• Check in: Admin Center > OData API Data Dictionary > [Entity] > Nullable

Scenario 2 – Error (job fails / record rejected)

An error is shown and the job fails.

• The target field is required in OData metadata: Required = TRUE
• Meaning: The field must contain a value (cannot be NULL/blank).
• Check in: Admin Center > OData API Data Dictionary > [Entity] > Required

Scenario 1 (Warning only)

• This is expected system behavior.
• Ignore the warning. The job can still complete;

Scenario 2 (Error / mandatory field)

You must ensure mandatory fields always receive a value:

1. Map the affected field in Integration Center (target entity field).
2. Provide a value for all records, for example by:
   • Mapping from a source field that is always populated
   • Setting a default/fallback value when the source is blank
   • Filtering out records where the required value is missing (if appropriate)
