Tax Code P1 doesn't appear in any GL account Item

Hi Team,

We are getting below error message while posting subsequent credit in SAP.

Tax Code P1 doesn't appear in any GL account Item; Message no. FF753

On PO History

GR is posted with $1000 - Quantity 4

Invoice is posted with $1100 - Quantity 4

Now we want to post a subsequent credit(as we don't want to change the quantity invoiced), but system is throwing above error message message.

System is triggering Inventory Account. If I assign tax category as '-', the system is allowing to post the subsequent credit.

Can I go ahead and update the tax category field in GL master data? Please suggest?

Regards,

Praisty
