I am using BAPI_SALESORDER_CHANGE, trying to change the sold-to party ('AG' or 'SP).
I have already used parameter partnerchanges, populating old_partner, new_partner, posnr '000000', updateflag = 'U' but I receive the msg that I cannot change the sold-to partner because on table TPAER, the non-modifiable flag is marked.
When I execute from VA02, it's ok. There are popus to redetermine a lot of atributes, but at the end it changes all the 4 standard partners. That's exactly what I want to do using BAPI.
Please.... I don't want to use batch-input!!!!
Thanks a lot,
