Invoicing Party relationship not carried through to PO in ECC

[ian_owen]

SRM 5 extended classic SPK12

Hello Gurus

We have our vendors synchronised with our R3 backend including the Invoicing parties. This all appears to work ok and can see them individually if we use BP. However, when we attempt to raise a PO against the actual order VN vendor #, when we check in ECC using ME23N, we do not see the invoicing party mentioned in the Partners tab, which causes problems when paying.

Have I forgotten something or am wrongfully assuming that the partnering function that is visible in ECC, does not carry through to SRM?

I've tried to go through all notes but don't see anything in there, which leads me to believe it's really obvious.

Thanks in advance.

Ian
