FICUSTOM401: FMDERIVE Consistency Check 01 (WRX RMRP)

[Former Member]

Hi,

During Invoice verification we are getting error FICUSTOM401: FMDERIVE Consistency Check 01 (WRX RMRP).

We have considered note OSS 2303301 and 2491908: FMDERIVE - FM Derivation Tool behavior starting on EA-PS 800 for the S/4HANA

We are using derivation rule FMDT_READ_PO_ASSIGNMENT. We have also implemented following derivation rule:

During Goods Receipt (FMDERIVE-TRANSAC = 'RMWE'): We are deriving a commitment item with financial transaction 40.

During Invoice Receipt (FMDERIVE-TRANSAC = 'RMRP'): We are deriving a commitment item with financial transaction 30

But we are still getting the same error at MIRO.

Any suggestion to resolve the issue will be much appreciated?

Hi,

There is something wrong in your rules. You cannot derive 'financial transaction'; you have to derive commitment item which has the required financial transaction.

Hi Eli,

Thanks for the reply. Are you saying, I need to update commitment item as one of the target fields in my derivation rules?

I have attached a new derivation rule screenshots with commitment items in it but still receiving the same error during MIRO.

I am not sure, how I can ensure that commitment item with financial transaction 40 is only derived for transaction key "WRX" and business transaction "RMWE" and 30 for business transaction "RMRP"?

Is it possible for your to attach your screenshot for derivation rules so I can understand it better?

Regards,

Vishal

Yes, you have to update the commitment items or rather make sure that they are correctly defined as explained in the note. Your new rule is still incorrect.

Is it possible for you to guide me where I am going wrong?

Any help will be much appriciated.

As I mentioned, you have to derive commitment item and not financial transaction. Financial transaction is an attribute of commitment item and can be only a source field in derivation strategy, but never a target.

Could you please share the derivation rule screenshot?
