So far,I become more familiar with dialog programming compared with past.But recently I encounter a new concept(also may be obsolete,I don't know),that is dialog Module,maintained in t-code SE24. I was confused, as you know,we can create a program with the type 'M' and create a serial of screens,afterwards,assign a tcode and run it. But referring to dialog module,it can be invoked with the key words 'CALL DIALOG' . So my question comes out,does the dialog module have any relation to previous dialog programming,or independent of each other? TKS.
