Functional Area Derivation for G/R and FI Documents

[Former Member]

Hi,

The instance is ECC 6.0.

Does someone know how is the Functional Area derived for GR and corresponding FI document. My understanding is that it is derived from the cost center (if no other subs or account assignment set up) which was used at the time of PO. So if by time of GR receipt the FA is changed on the cost center master, the GR doc will still getting the FA area which was derived at the time of PO. Is this correct?

Do you use Funds Management (FM) Derivation rules?

In our system, the Functional Area is derived from the Fund Center in the FM Derivation Rules (not from the cost center master data).

In other words a cost center is manually keyed during the document entry, an assignment moves the cost center (source field) to the fund center (target field), then the FM derivation rule is triggered that assigns the functional area based on the fund center. Because its an FM derivation rule, when any FM entry posts the functional area will derive from the values in the derivation rule at the moment the FM entry is created.

So if we have a PO that has functional area A and we change the derivation rules so that the cost center's functional area will be B, the goods receipt will create an entry with functional area B, not the one that was in the PO.
