I have this question about INV Production Order.

Imagine I have this simple BOM structure where item B (purchase item) is a child of item A. These items are having the following parameter settings ;

For Item A
Order Policy : Anonymous
Order System : SIC
Order method : Lot-for-Lot
Reorder Point : 10

For Item B
Order Policy : Anonymous
Order System : SIC
Order method : Lot-for-Lot
Reorder Point : 0

After running session “Genarate Planned INV orders” (tdinv3201m000), I got an Planned INV Production Order of 10 pcs for item A. The planned start date for this order is today date.

There is no planned order for item B unitl I transfer the planned INV order to become a SFC order.

In this case, how will I know that I need to purchase item B ? By the time I know (after creating a SFC order), then it will be too late.

Any comment are much appreciate.

Correct me if I'm wrong, but aren't these the basics for SIC?
Also item B will need a re-orderpoint to stay ahead of shortages. Otherwise MRP is the way to go..........

Hi Hutje33 ,

I agreed with you.

It is possible for item A to be controlled by SIC and item B by MRP ?

What our bussiness needs is have item A control by inventory level. Once there is planned INV order for item A, all the child for item A (that is item B) will be automatical allocated.

Hi Teddybear,

I'm afraid you're turning it around for what's supposed to be "normal".

In normal situations the upper level is MRP-controlled, which effects allocations for the lower levels. The lower level (semi-finished products or raw mat's/Purchase items) can be SIC or MRP.

Hi Hutje33

I have a last question.

Why the allocation from the INV Production Order is not cascaded down to lower level as allocation.

Example : we have a Planned INV Production Order for item A and item A need item B. Why don’t BaaN generate a Planned INV Purchase Order for item B ?

I know this is the case but just can’t figure what is the reason for this.

Basic idea behind this method is, that reordering for lower level is supposed to be done based on reorderpoints/safetystock instead of allocations from upper levels i guess.
