Costa,

Hard to say without looking at the program and tables, however it reminds
me of an issue I?ve seen in the past where a program updates a record -
changing a field which is not part of the key list it is reading by, but
another file sharing the same access path causes the program to pick up

the

same record on its next read. Thus processing it twice.

If not that - is the file open for shared access? Could B occasionally be
moving the file pointer for A?

Hello,

The whole team I work with is facing a weird issue.

Program A loops per order and calls program B, program B is doing just

a

write to a file (order lines) using the input parms from A.

Occasionally though, program B is writing 2 lines (duplicate) for some

of

the order lines, not all. By deleting the records and rerunning the
process, no duplicates are written.... So we can not reproduce the

fault.

I added a FEOD in pgm B, but we still get the duplicates once in a

while.

The release is V7R1M0.

Both programs are RPGLE, in DFTACTGRP.

Any hints?

Thank you in advance,
Costa
