You can use it to change customers' own fields in vendor invoices.
You can use the Business Add-In (BAdI) MRM_ITEM_CUSTFIELDS to integrate a subscreen of your own at item level to process customers' own data. The Customer Include CI_DRSEG_CUST is available for customers' own fields. The structure DRSEG_CI contains the fields C_RBLGP (document item in invoice document), C_KOART (account type), and Customer Include CI_DRSEG_CUST. The structure DRSEG_CI is already contained in the structures DRSEG (invoice item (dialog processing)), MMCR_FRSEG and MMCR_RBMA. If you wish to save customers' own fields to the database, you must attach these fields in an APPEND structure to the corresponding database table (RSEG, RBDRSEG, RBMA). For G/L account lines, add an APPEND structure with the customer's own fields to the structure COBL_MRM. The customer's own fields then also exist in the database table RBCO.
The customer's own fields can be processed on a separate subscreen during online invoice verification with the aid of the Business Add-In MRM_ITEM_CUSTFIELDS. The following data is available for this purpose:
Transaction type (Create, Change...)
Invoice document header
Invoice document items (items with PO reference, items with G/L account posting, items with material posting)
Note:
In the case of automatic transactions, the customer's own fields cannot be populated.
Requirements
To implement this BAdI, you need ABAP knowledge to create the subscreen and for the flow logic.
Standard settings
The Business Add-In cannot be used multiple times.
The Business Add-In is not filter-dependent.
