GR/IR behaviour in PSM (FM) with update in both GR/IR

Question

Hello Gurus,
I'd like to ask which is the correct behaviour in PSM when Updating in both GR/IR (in OFUP transaction).
I'm getting the following behaviour from the system:
Goods receipt:
FI document:............... =>......PSM Document:
Expense acct E  100...............Funds ctr AAA /Comm Item AAA   100  (from expense acct E)
Clearing acct     -100
Invoice Receipt:
FI document................ =>.....PSM Document:
Clearing acct        100................Funds ctr AAA/ Comm Item AAA   -100 (inheriting expense acct E)
Supplier acct       -100................Funds ctr AAA /Comm Item AAA    100 (from clearing account)
If you analyze this from PSM perspective its correct, because the impact in Funds ctr AAA/ Comm item AAA is 100, but when comparing it to controlling real items, there is a difference due to the fact that the expense account E would have a balance of 100 in controlling and 0 in PSM.
Is this correct anyway?
Thanx a lot!!

Hello Mariano,
The mapping should be:
Expense account (say, the gl code is 3999999) -> cost element 3999999 -> CI 3999999 30/3 (derived through any desired method)
Clearing account (say, the gl code is 1999999) -> CI 1999999 40/3
Vendor reconciliation accout (say, the gl code is 2999999) -> CI 2999999 60/3
When a PO is created the system derives the FM account assignment for the PO line item. In the above case CI 3999999 will be derived through cost element and a funds center will be derived through a CO object (cost center, internal order, etc).
During IR process, the system bypasses the derivation mechanism. Instead, the account assignment is inherited from the PO line. So, you should get DR 3999999 and CR 3999999 in FM for the LIV postings.
Hope this clarifies the matter.
