Substitution rule is not transported

Hi Experts,

I have transported a validation and substitution rule from DEV into QAS. But after importing transport request, validation rule is fine. But it looks like only prerequisites of substitution rule are available, but substitution field is missing. I also have regenerated via program - RGUGBR00.

Substitution field is ZUONR (assignment number)

am I missing something?

Thanks,

Sukhbold
