How to manipulate PO communication language

Dear colleagues

I would like to ask if anyone already did try to manipulate the PO communnication language (EKKO_SPRAS) as per certain customer requirements.

My requirements are that PO communnication language would not be pulled from vendor master data but could be determinable by predefined logic.

Which user exit/BADI could be used?

Any hint will be highly appreciated.

Best regards and thanks to anyone who contributes
