Account Determination for entry GCOA PRD not possible

Question

Hi!  we encountered this error during Invoice Receipt.   During IR, there is a decimal difference between the Invoice Balance in mir7 (in the upper right)  and the PO amount.  What we do is we put the the decimall difference in the Unplanned Del Costs under the details tab.  But our problem is we encounter the error message Account Determination for entry GCOA PRD not possible.   I read that in the transaction key PRD:  Price differences can also arise in the case of materials with moving average price if there is not enough stock to cover the invoiced quantity. In the case of goods movement in the negative range, the moving average price is not changed.  Instead any price differences are posted to a price difference account.
The material in the PO that we are trying to IR have stocks in the system.  My question is how can we know the number of stocks that should be available for us to be able to IR?
How can we also avoid these decimal differences between the IR and PO amount?
Thanks so much and appreciate your help..
Regards,
Paula

Answer 1

first thing
If there is small diffrence in Invoice total amount send my vendor and system calculated value and ther is small diffrence then it shoudl go to small diff account
this account should go in OBYC GCOA DIF hear u can give gl account , and also check if u have stet tolearance limit for this amount
SPRT ==MM == LIV == invoice block == Set Tolerance Limits
in this u set BD for ur company code.
if u do this then u will not require to put that small diffrence in unpland delivery cost.
Account Determination for entry GCOA PRD not possible
in OBYC for ur GCOA  click on PRD key
and following should be the entry for ur Material valuation class
general modification      valuation class    gl account
(blank)                              xxxx                    xxxxx
PRA                                  xxxx                     xxxx
PRF                                   xxxx                      xxxx
PRU                                  XXXX                       XXXX
depending on ur posting rule set this
hope ur error will go
My question is how can we know the number of stocks that should be available for us to be able to IR?
when do MIRO or MIR7 system check what is the stock qty availabe at the point of posting
say Stk is 10 and u are posting 15 qty than system calculat the value for 10 and post the amount for 10 as inventory cost and remaning 5 will post to price dif account  if ther eis change in rate of PO and invoice received.
hope this helps
