Hi everyone,
This is my first post here and it looks a bit complicated so apologies if any of it is not clear;
I have some questions about how purchase requisitions are considered by MRP when reusing PREQ numbers;
The business have recently moved to reusing/recycling the PREQ numbers. This has been going okay but a user noticed some strange behaviour recently and is looking for an explanation.
EXAMPLE:
2 PREQ numbers exist from the last MRP run.
PREQ 01 is suggested to be delivered first, based on release date and delivery date in PREQ.
PREQ02 is at a point in the future after PREQ01
Same 2 PREQ numbers still exist after MRP run.
PREQ 01 is now changed after MRP. The release date and delivery date are now far into the future.
PREQ02 has not been changed by MRP so the original dates are as before.
However, because the PREQ01 has been changed, PREQ02 is now ahead of PREQ01 in the calendar but not on the stock requirements list (based on number range value I guess?)
So, questions;
1. Has the second MRP run changed the original contents of PREQ01 or deleted the contents entirely and assigned new information to the recycled PREQ number? I do realise that the MRP settings will influence this too so a general conceptual idea of how recycling works would be useful.
2. How is the stock requirements detail list sorted? By PREQ number (element reference number) and then date? Or date and then PREQ number? And can this be customised so we are always seeing the priority elements (e.g. earliest required PREQs) at the top of the list?
I'd appreciate any help I can get with this as I can't seem to find any answers in the places I looked so far.
