When adding an invoice to a Client record in Accounts Receivable, the Sales Tax drop-down menu is grayed out on the Invoice tab even though users are able to create Sales Tax Items in Configuration, Products and Billing Items.
Change the Business Rule to allow the organization to collect Sales Tax:
1. Log into Financial Edge as a user with rights to access Business Rules. 2. In Accounts Receivable select Configuration. 3. Select Business Rules. 4. Highlight General. 5. Change the Sales Tax option to "our organization collects sales tax".
