Line item: SD incorrect account information in header

You are in the line item display for vendors or customers. On the selection screen, you have selected field "Vendor items" or "Customer items". In the headers for these items, information is either missing for the account or does not apply.

The corresponding vendor or customer account for the vendor or customer is defined in fields LFA1-KUNNR or KNA1-LIFNR. Starting from this account number, the system reads the master data for the incorrect account type. If the vendor and the customer account are identified with the same account number, then the system displays the master data of the vendor in the header for the customer account and vice versa. Otherwise, the fields usually remain blank in the header.
