I have the following problem when generating payments using checks
Access denied bank account number field (AccountNum) of Table Print Checks (TmpChequePrintout).
How I can fix it
Are you using AX as administrator or do you have a specific role assigned? If you have a role, this one must be extended with permissions on the temporary table (TmpChequePrintOut).
If you are not able to do this, ask your system administrator or implementation partner for help.
this is most common error while generating payment via check.
all you need to do is to assign security roles like account payable clerk or something related to that.
P.S: after assigning roles please restart (close and than open)AX.
Please mark correct if my answer helped you.
