FICUSTOM401: FMDERIVE Consistency Check 01 (WRX RMRP).

Hi,

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

We have considered note OSS 2303301: 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:

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.

What can you suggest?
