Material Group - Valuation Class - G/L A/c Assignment ?

Hi,

While posting PO for Non - Stock material group, the G/ L a/c XXXXXXXX assignment is not happening automatically.

I have checked config set ups in OMQW (Assignment of Material Group with Valuation Class), OME9 and OBYC and everything seems to be correct.

Hence looking out for experts guidance.

Thanks,

Milo
