Another relevant nuance discussed not so long ago in BPCS_L is that when 
orders are closed & purged through CST900, they update cost master based on 
the actual cost in those shop orders & they use the actual cost of sub 
components in the cost master.

Thus, ideally, you want the lower level component orders to get closed & 
purged before doing that with the next level that those items were used in 
the production of, otherwise you end up updating costs on sub-assemblies in 
the absense of correct costs going into the product.

One way to accomplish that is by releasing the lower component parts shop 
orders first, so that when you purge shop orders in shop order sequence, this 
gets the actual costs correctly up-to-date for you.

Also if, like us, you have some fluctation in the due dates of the customer 
parts, you have released shop orders based on the requirements for the end 
items, and if you not doing that production for a while, this introduces a 
nightmare of adjusting due dates of intermediate components.

MRP only changes dates of planned items, not firm planned by shop order 
release, so level 1 requirement date changes, level 2 has MRP reccomended 
date change & if you not change that shop order due date, level 3 is still 
sitting at due date based on level 1 before its date got changed.

You avoid that nightmare by releasing bottom level parts & not releasing 
higher level until closer to date that they really need to be produced.
