Re: 405cd - Start dates change?

Don,

You have a planned order with a start date and a release date. The
difference between the 2 is your lead time.
When you release the order in MRP540 using action code 11 (forward
schedule), you are using the release date as your start date and calculating
a new due date based on your routing (run + move +queue). Action code 12
(backward schedule) you would use the due date to recalculate the release
date.

In the 'planning' side you use lead time, when you release an order you are
in 'execution' mode and you use the routings.

Subject: [BPCS-L] 405cd - Start dates change?

Confusion:

I enter a forecast and run mps

I run mrp and cap

I have a planned order with a start date

Then, I release that planned order to a shop oder, and the start date rolls
"back".

What is the logic causing that start date to change - on the shop order?

TIA,
Don C.
