Re: PERFOMING ROLLBACK FUNCTION USING IMSDB CALL.
Posted: Wed Nov 27, 2013 8:27 pmThe reason for using a flat file in between would be to avoid the need to roll back. The first program would process what ever it needs to make sure the records match completely. It would make sure that you have everything needed to do the full update. If not, it would not write the flat file out.
Then, the second program would do only the updates that would work all the way. It would never need to roll back because the work had been pre-checked by the first program.
