Hi Jitin,
I will test reply for 2nd question and revert.
For 3rd question, even after I enter the Unit Price and Tax Code, the Gross Price field is not accessible. The field is skipped and using mouse also, I am not able to take the cursor there. I have made the field Active in Form Settings.
I have attached screenshot for Form Settings and the AP Invoice and AR Invoice.
Any system initialization settings?
My SAP Version 9.1 PL00.
