How to attach adobe form to a standard transaction code

Hello,

I would like to know how to attach a adobe form to a standard transaction like FINT ou F.26.

In a way that running the transaction runs the adobe Form.

I found that some people use NACE transaction and others use OB84.

But in the case of Nace my transaction does not seems to be in the list. (I had a hard time listing all transaction.)

In te case of OB84 it really seems not to work.

Please Help.

Best Regards.

Abdou
