• What is the cause and solution for SAP error message LE_SHP_ODATA_API_OD028 - Custom fields of multiple referenced document items must be identical ?

  The SAP error message LE_SHP_ODATA_API_OD028 indicates that there is an issue with the custom fields of multiple referenced document items in an OData API call. This error typically arises when you are trying to create or update a shipment or delivery document, and the custom fields that are supposed to be identical across multiple items are not matching.
  Cause:
  
  Inconsistent Data: The custom fields for the items being processed in the OData request are not identical. For example, if you have multiple items in a shipment and each item has a custom field that is supposed to have the same value, but they differ, this error will occur.
  API Constraints: The OData API may have specific constraints that require certain fields to be uniform across related items. This is often the case for fields that are meant to represent shared attributes or characteristics of the items.
  
  Solution:
  
  Check Custom Fields: Review the custom fields in the OData request payload. Ensure that the values for the custom fields are identical for all referenced document items.
  Modify the Request: If you are sending a batch request with multiple items, ensure that the custom fields are set to the same value for all items that are being processed together.
  Validation: Implement validation logic in your application to check for consistency in custom fields before making the OData API call.
  Documentation Review: Consult the API documentation to understand the requirements for the custom fields and ensure compliance with those requirements.
  
  Related Information:
  
  OData API Documentation: Review the specific OData API documentation for the shipment or delivery process you are working with. This documentation often provides insights into required fields and constraints.
  SAP Notes: Check for any relevant SAP Notes that might address this error or provide additional context or solutions.

  SAP Community: Engage with the SAP Community forums or support channels for additional insights or similar experiences from other users.
  
  By ensuring that the custom fields are consistent across all items in your OData request, you should be able to resolve the LE_SHP_ODATA_API_OD028 error.
