Standard Invoice Tax only credit

Greetings:

A handful of GEO codes are preventing adding a standard invoice to credit tax only.

Steps to duplicate:

Key Sold To, Company, Invoice Date, GL Date, Payment Terms

Gross Amount

Tax Amount

Tax area (tax area of ship to, not default from Customer)

Tax explanation code

The gross amount and tax amount are then blanked out (with some GEO Codes).

Thus not able to save the RM nor key the distribution.

Thanks,

Jeanne Alfred
