One Write, two records....

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
