Hi Exson and thank you for your reply
Yes, I have understood that Assembly in this concept is wrong, I have already changed to Manufactured. (that's why "assembly" is in double quotas)
..but still, when both Phantom and Manufactured/Bought items shows up as shortage, then I start to be confused.
If we ignore the Phantom for now, let me try to explain more clearly:
This is a simple list of a Manufactured Item tree:
- 50001 M ManufacturedItem1 (0 items in stock)
- 10001 B BoughtItem1 (1 item for build, 10 items in stock)
- 10002 B BougthItem2 (1 item for build, 10 items in stock)
- 10003 B BougthItem3 (1 item for build, 10 items in stock)
All parts are either Bought or Manufactured
If i have 0 Items left in stock of item 50001 the "List Components Required" shows correct shortage qty for all items.
If i creates a WO of lets say 4 items of 50001 with auto-issued 1 pcs of all parts beneath, all items is correctly drawn from my stock when returned (6 items left of all 1000*, and +4 pcs of 50001 in stock.
When i now run the report "List Components Required" for a higher level where 50001 is a part (1pcs) it shows:
- 50001 (Build qty: 1, Shortage -3) - Correct, it's in stock
10001 (Build qty: 1. Shortage -5) - Not Correct (its a part of 50001 in stock)
10002 (Build qty: 1. Shortage -5) - Not Correct (its a part of 50001 in stock)
10003 (Build qty: 1. Shortage -5) - Not Correct (its a part of 50001 in stock)
Edit:
A little bit more complicated situation occurs when i want to use let say 4 items of 50001 but only have 3 of them in stock.
..or when the same part participating in several different parent items.
The correct report should then only show shortage for items in the missing parent item?
..as well as shortage for the missing parent item it self?
The problem is that i am not sure we have built up this ERP correctly and therefore i want to be 100% sure before i flag this as a misleading report leading to serious consequences when we start purchasing parts based on this.
Another question i have asked my self about is how MRP treating this, which i don't have had time to analyze yet.
I want to be sure the base is correct before starting on that chapter.
