PCA substitutions and PA derivations

[Former Member]

Dear all,

We have COPA standard derivation with incoming SO activated. We have also PCA substituions on Profit Centers -> 0kem, at SO creation and billing....

The thing is that when i create an SO, or Invoice... it seems that the system makes first substituion and then derivation... and we have porblem..

1) do you know maybe where to set up when substitution works ? at the beginning or the end.

2) The other thing is .. at what time system derive the COPA segment ? - only at SO creation or also at Invoicing ?

Regards,

Lukasz

What is the need to use two modules to do the same task. Is it possible to remove the derivation in COPA, which would be taken care by PCA substitution.

If PCA substitution does not address those items, may be could you rewrite the derivation to exclude those that are already governed by PCA.

In PCA, substitution occurs at the time of Callup point defined, which tells you exactly when the validation or substitution is called

Both sales order and billing documnets can be mapped to COPA.

Dear Sridhar,

SAP technical solutions has to follow business logic and not other way around, so it is the reason why we have 2 modules doing the same task.

We want COPA only in company code A, but in B we dont want it, but we have still one controlling area. So this is why ...

Removing derivation in COPA is not possible (we use standard derivation steps), what I can do is to create new derivation step to replace the substitutions..

Yes the call point.. but call point is .. creation of sales order... the when it is taking place ? at saving the document ?, during the entry ?

Sales and billing documents can be mapped..., but how it really works in particular case. I have incoming SO activated, but I dont have to activate incoming Billing Docs, so it is a standard I suppose that system derives at billing.

so it derives PA segment in 2 points of time, at the creation od SO and billing.. right ?

Is the logic behind my note correct ?

Thank you for your help

"SAP technical solutions has to follow business logic and not other way around"

Doesnt quite work like that. You are restricted by what SAP can do.

Take a look at BTE (business transaction events) (Txn FIBF). Try using them instead of Substitutions / derivations.

<b>Yes the call point.. but call point is .. creation of sales order... the when it is taking place ? at saving the document ?, during the entry ?</b>

The activation of substitution, in general, takes place, at the time of saving. However if a simulation is done, the subs could be triggered as well.

<b>Sales and billing documents can be mapped..., but how it really works in particular case. I have incoming SO activated, but I dont have to activate incoming Billing Docs, so it is a standard I suppose that system derives at billing</b>

In transaction KE4I, when you map the SD condition types to value fields, the billing documents are mapped. As long as this is done, values are expected to flow into COPA.

<b>so it derives PA segment in 2 points of time, at the creation od SO and billing.. right ?</b>

Yes.

In terms of order of documents, FI >CO>PCA-->COPA.

The first three play important roles and are integral part of the transaction.

COPA does an analytical role.
