Hi AA,
Can you try running the heuristics in the standard Planning Book/Data View 9ASNP94 / SNP94(1) and compare the results from you data view. Also validate the iterations & periods for the macros -Stock balance and Safety Stk/Reorder Point/ Targt Stock Level. One last thing would be to check the sequence of macros under the events (Default, level change, start, exit).
Regards
AK
