Hi,
In your post you mentioned that "the CC in the PO header is only used to determine the currency of the PO." But if we use different CC then system will not accounting documents.
Ex :- Inter company PO # 4500000*** from plant AAAA (CC CO01) to Plant BBBB (CC CO02).
In header data of PO - CC= CO05, Pur org = 1234, Pur grp = 33
All three CC has same currency.
System allows to create PO, Delivery, PGI, but when billing doc created it will not generate any accounting docs.
If we change the CC in PO header to CO02(belongs to plant BBBB) then it will create accounting doc.
Do we have any config, message or OSS notes which throws error/warning when STO is entered with different CC.
