JITO1 show "cannot be executed"

[former_member211576]

Hi experts,

We need to use JIT calls and I run JITO1. The error message

return "transaction code JITO1 cannot be executed". I have checked SFW5

and enable enterprise_functions & enterprise_bussiness_functions. I

found it's very strange. Sometimes I can run without any errors but

somestimes(just 1 minutes later) I can't. Please help.
