How to update vendor address based on vendor control data

Hello,

i have a request to update one field (Search term 2) from Vendor master Address view:

Clik here to view.

based on industry code populated for the supplier (LFA1-BRSCH):

Clik here to view.

This means if industry code is populated, address field SORT2 must be updated with corresponding wording for this code.

How is it possible to do this?

I cannot use BAdI definition name ADDRESS_UPDATE as ADDRESS1_SAVED method is triggered only if one address field is modified.

I found VENDOR_ADD_DATA enhancement spot with VENDOR_ADD_DATA BAdI definition: can i use SAVE_DATA method?

If yes, which function module can i use to update LFA1 table? Is it OK with CHANGEDOCUMENT_SINGLE_CASE?

Thank you for your help.

Regards.

Laurent.
