Hello Experts,
I am facing some problem while creating a PO in ME21N. First problem is :- Account Assignment mandatory for material xxxxxx (enter acc. ass. cat.) Message No.- ME062.
I have searched for the solution of this problem even in SAP community but everybody answered to go for T.code- OMS2 and tick Value update and quantity update. But I have already ticked that before but still the error is coming. So tell me how to resolve the issue. I have attached the screenshot below. Please check it and suggest me .


Here I am facing another problem while creating PO. System is not taking the material price from the material master after giving all the information. When I check it the system automatically blank the net price field and also asking for :- Please enter required condition. Message no.- 06209.
Please help me . I have attached the screenshot below. Kindly check it.

Regards,
Shreekumar
