My Tax Setup gives error "Tax Explanation Code Invalid"
I have setup Tax for a New Company. Everything seems ok except when entering Journal Entries using the F0911 Begin Doc, Edit Line, Edit Doc and End Doc on a Custom screen, we get the error 0748 Tax Explanation Code Invalid. Oracle Support will not help us with our Tax Setup because the error appears on a custom application. The Tax setup appears to be correct but I can't be sure. I have checked the entries several times for the Company, Cost Centers, GL Accounts, AAI's, etc.
It does work for most Tax. The JE's are only not working for one of the GL Class Codes. I have checked the AAI and GLC and it seems Ok.
