Materials management small differences - DIF - Profit Center assignment.

Question

Hi,
We have created one G/L for posting the u201CMaterials management small differencesu201D at the time of generating MIRO document via transaction u201CDIFu201D in Tcode - OBYC.
For e.g. if the GR amount is 90 and IR (Invoice received from party) is of Rs. 91/- or vice-versa then for posting the difference of Rs. 1/- we have made the above assignment.
System is generating the line item for the u201CSmall Diff -Invoice Verificationu201D but posting automatically to a "Dummy Profit Center u201C in the absence of any other data.
Our point is that we want to change the profit center to the related Business area, which is there in the line item of u201CSmall Diff -Invoice Verificationu201D account.
We tried the FI substitution (Tcode u2013 GGB1/ OBBH) for the Profit Center derivation on the basis of Business Area but that is working with the FI documents (Manual FI entry) only and not with the automatic line generation like MIRO in the above case.
Later on I tried Tcode u2013 OKB9, but in that case after giving business area wise cost center substitution, system is correctly showing the entry (in simulation mode of MIRO transaction) in the required Cost Center & on that basis in the Profit Center, but still system requires u201CCO-Objectu201D
Initially we tried other way of creating a Cost Element under the category of u201C11 u2013 Revenueu201D to maintain Business Area u2013 Profit Center link but still in that case also it requires co-object hence turned to changing the Cost Element Category to u201C1 u2013 Primary Costu201D for capturing Profit center on the basis of Business Area u2013 Cost Center link since basically G/L u2013 u201Csmall Diff -Invoice Verificationu201D we have created under u201CExpense Groupu201D.
Our requirement is to post the entry in related profit center per Business Area in the line item of "Small Diff -Invoice Verification" since there are 6 to 7 business areas, which are active in system.

Hi,
Thanks for the reply. But I would like to correct you. I have mentioned in my subject line - "DIF" i.e the Transaction Key maintained in Transaction Code - OBYC for posting the small difference (Between GR and IR values) arriving at the time of MIRO transaction posting.
Now meanwhile I have come across u201CSAP Note : 32654u201D which mentioned that "Account assignment for the transaction (KDR, DIF, UPF) on the highest level i.e. the 1st screen where we set the Cost Center or Profit Center assignment to Cost Element with Acct Assignment details (1 or 2 or 3) is possible.
Same is not possible on details level means Acct Assignment details level per Valuation Area or Business Area for Cost Center or Profit Center linkage (2nd screen of OKB9).
Please do correct me if I am making any wrong statement.
Now would like to have an advise about the transaction Code - OKC9 with the scenario (MIRO document u2013 Dummy Profit center linkage) that I have mentioned above.
Do I require to maintain OKB9 (At highest level) and then need to work out CO- Substitution via OKC9 ? Or OKC9 is enough to cover my scenario ?
Do any body have a knowledge about that? Points will be assigned.
