Time-Based Genealogy & Slot Configuration: Slot Qty never decremented.

[Former Member]

Hello experts,

I am trying to make the time-based genealogy and slot configuration work for this scenario:

There is an item M1 to manufacture with two components M2. There are bags with 1000 items M2. The worker opens the bags and dumps the items M2 into a funnel at the machine. The machine takes the items M2 to manufacture M1. In ME the worker has to do the inventory receipt for this bags to get an inventory id and to collect the number printed on the bag. Afterward he has to add the bag to the slot for M2. He enters the previously generated inventory id and the slot quantity (always 1000).

My problem is that ME never decrements the slot quantity. Here are my configuration and manufacturing process steps in detail.

Configuration

1) 2 new data types
    +) INV_FOR_SLOT with system data fields INVENTORY_ID and SLOT_QTY
    +) BAG_NO with new data field BAG_NO
2) An operation O1
3) A routing R1 with operation O1
4) A resource with 
    +) Process Resource checked
    +) Default Operation = O1
    +) Activity Hook PRE_COMPLETE = SLOT_QTY_DECREMENT enabled
    +) System Rule 'Time-Based Resource (Genealogy)' set to true
5) A material M1 to manufacture with
    +) Lot Size = 1000
    +) Routing = R1
    +) BOM = B1
6) A material M2 to purchase with
    +) Lot Size = 1000
    +) Data to Collect on Assembly = INV_FOR_SLOT
    +) Data to Collect on Inventory Receipt = BAG_NO
    +) Time Base Component Type = Continuous
7) A BOM B1 with component M2 at operation O1 and quantity 2.
8) A releaseable Slot Configuration S1 for BOM B1
    +) Activated for Resource R1

Manufacturing Steps

1) Inventory Receipt
    +) Material = M2
    +) Quantity = 1000
    +) Value for data collection BAG_NO
    --> An Inventory ID INV1 with Qty 1000 has been created.
2) Resource Slot Config Setup
    +) Resource= R1
    +) Slot 1: Add M2 and enter Inventory ID INV1 and Slot Qty 1000
    --> The quantity on hand from inventory INV1 has been 
        moved to 'Cum Qty' of Slot 1.
3) Create and Release Demand
    +) Material = M1
    +) Quantity = 500
   --> SFC 1 generated.
4) POD
     + Start and Stop SFC 1

First take a look at the As-Built Summary of SFC 1. The assembled quantity of component M2 is set to 1000 (2 * 500). Good! The collected data (bag number, inventory id and slot quantity) is attached. Good!

Finally take a look at the 'Resource Slot Config Setup' of resource R1. The 'Cum Qty' of Slot 1 is unchanged, although the Activity Hook PRE_COMPLETE = SLOT_QTY_DECREMENT is set and enabled!

Any hints?

Best regards,

Martin

Hello Martin,

Check that the BOM component Revision for M2 is the actual Material revision of INV1 not * / # (shows as blank in BOM Maint GUI).

Hello Andrew,

thanks a lot! It worked with the actual material revision set in the BOM. What is the reason for this restriction?
