Tax in punch-out catalog

Dear SRM Guru's,

Our customer has SRM5.0 runnig in Classic mode.

Tax determination is set to be done in the back-end.

Now we are about to add a new punch-out catalog of a supplier and in the OCI they also send a tax code.

My question is if it possible to adapt this tax code in the SC and follow-on documents.

Is the BADI BBP_DET_TAXCODE_BADI a possibility?

Thanks in advance!

Henri
