Cannot create Custom Fields for Material Document Hea...

[#1]

Hi SAP Community,

We are working on an SAP S/4HANA Cloud Public Edition environment under SAP GROW, and we have encountered a limitation regarding Custom Fields at the Material Document Header level.

Our scenario:

We have a custom Fiori freestyle application that posts Material Documents via the I_MaterialDocumentTP RAP BO. In this application, the user enters an "Ingress ID" which is stored in the Reference Document / Material Document Header Text field (XBLNR / MaterialDocumentHeaderText). This Ingress ID is a key to a custom Z table that holds carrier/transport information (driver name, vehicle plate, tare weight, and gross weight). We need to display these four fields on an Adobe Form associated with the Material Document printout.

The problem:

To achieve this, we need to create four Custom Fields at the Material Document Header level so they can be populated during posting and later consumed by the Adobe Form. However, when we go to the Custom Fields app, the Business Context "Inventory Management: Material Document" (header level) is not available. We can only find "Inventory Management: Material Document Item", which only allows creating custom fields at the item level.

We also explored the available BAdIs:

• MMIM_ITEM_PROVIDE_DATA — This BAdI works at the item level. We can successfully enrich item-level custom fields, but it does not give us access to header fields like the Reference Document or Header Text.
• MMIM_HEAD_PROVIDE_DATA — This BAdI works at the header level and provides access to header data. However, since we cannot create custom fields at the header level (due to the missing Business Context), there is no target field to write the transport information to.

What we need:

We need a way to create custom fields at the Material Document Header level, or an alternative approach that allows us to store four carrier-related fields (transport name, driver, plate number, tare weight) at the header level so they can be consumed by an Adobe Form during the Material Document printout.

Our questions:

1. Is the Business Context "Inventory Management: Material Document" (header level) planned for a future release? If so, which release or timeline?
2. Is there an alternative extensibility approach to add custom fields to the Material Document Header in S/4HANA Cloud Public Edition while remaining Clean Core compliant?
3. Has anyone faced a similar requirement and found a supported workaround?

Any guidance would be greatly appreciated. Thank you.

Hello @LBONAR22 

Use item-level custom fields (if acceptable for form mapping).
Store data in custom table  and fetch it in Adobe Form logic using the header text (XBLNR) as key.
Use MMIM_HEAD_PROVIDE_DATA BAdI to enrich data at runtime (without persisting custom fields).

Thanks,
Sravan
