Hi Sunil,
Yes, i use the other user but i want to solve the problem. ^^
i also have another issue.
I've created a custom BO and WoC then assign it with Business User (already created BAC/ check in/activate and deploy the solution)
however, when I login with Business User and go to a custom WoC, message "You are not authorized to change the data" occurred, and cannot create any instance for that BO.
thanks for your recommendation
Best regards,
Thanarat
