How can I create 1 DDM that fetches 3 ADABAS files
simultaneously?
Answer Posted / aswini
Hi,
In general the DDM is part of a single Adabas file and we
the programmers play around the views of DDMs.
It is possible that there can be multiple views of a same
file, but I never heard that there can be one DDM from
multiple files.
May be what Jaydip has told is correct and a good learning
for me.
