COMEXCEPTION: (50050) ERROR FOR ITEM(S): {ITEM} NOT ENOUGH FREE STOCK, OR STOCK DOES NOT EXIST

Updated December 19, 2022 08:54

When you want to produce an Item you get an error message

‘COMException: (50050) Error for item(s): {ItemCode} Not enough free stock, or stock does not exist.’

The raw material has Best Before Date
The ‘Picking order by’ setting is FEFO in the Picking for production controller
You have negative quantity on the Lost and Found location (found stock)
In this example
- the production needs 210 kg raw material
- 5L_IN is the input location of the production line
- LAF100 is the Lost and Found location

Scenario 1
Steps	Storage location	BBD	WMS Stock	SBO Stock	Comment
Initial state	5L_IN	29.09.23	62	1062	The table only shows quantities of item with ID:'17000004'
Initial state	5L_IN	15.06.25	1000	1062
Cycle count	LAF100	29.09.23	-8	1062	Lost and Found (virtual) location shows -8 (meaning: should do a Goods Receipt with quantity 8)
	5L_IN	29.09.23	70		After Cycle Count, the inventory shows that the quantity is 70 for the item with BBD:29.09.23
	5L_IN	15.06.25	1000		The Qty:8 is still missing from SBO Stock
Start production	LAF100	29.09.23	-8	1062
	5L_IN	29.09.23	70-70 = 0		Production needed Qty:210 from 5L_IN (it allocates quantities for consume)
	5L_IN	15.06.25	1000-140 = 860
End production (consume)	5L_IN	29.09.23	70-8-70 = -8		Process is refused, because Not enough free stock. This quantity 8 must be consumed in order not to violate the FEFO principles

Scenario 2
Steps	Storage location	BBD	WMS Stock	SBO Stock	Comment
Initial state	5L_IN	29.09.23	62	1062	The table only shows quantities of item with ID:'17000004'
Initial state	5L_IN	15.06.25	1000	1062
Cycle count	LAF100	29.09.23	-8	1062	Lost and Found (virtual) location shows -8 (meaning: should do a Goods Receipt with quantity 8)
	5L_IN	29.09.23	70		After Cycle Count, the inventory shows that the quantity is 70 for the item with BBD:29.09.23
	5L_IN	15.06.25	1000		The Qty:8 is still missing from SBO Stock
Process Cycle Count	5L_IN	29.09.23	70	1070	After Cycle Count, the quantity -8 disappears form LAF100 and the quantity 70 is realy on stock on 5L_IN location. So, quantity 8 thus already appears in the SBO stock.
Process Cycle Count	5L_IN	15.06.25	1000	1070
Start production	5L_IN	29.09.23	70-70 = 0	1070	Production needed Qty:210 from 5L_IN (it allocates quantities for consume)
Start production	5L_IN	15.06.25	1000-140 = 860	1070
End production (consume)	5L_IN	29.09.23	0	860	Successful production
End production (consume)	5L_IN	15.06.25	860	860	Successful production

Scenario 3
Steps	Storage location	BBD	WMS Stock	SBO Stock	Comment
Initial state	5L_IN	29.09.23	62	1062	The table only shows quantities of item with ID:'17000004'
Initial state	5L_IN	15.06.25	1000	1062
Direct Cycle Count	5L_IN	29.09.23	70	1070	After Cycle Count, the inventory shows that the real quantity is 70 for the item with BBD:29.09.23, because the Goods Receipt is executed immediately
Direct Cycle Count	5L_IN	15.06.25	1000	1070
Start production	5L_IN	29.09.23	70-70 = 0	1070	Production needed Qty:210 from 5L_IN (it allocates quantities for consume)
Start production	5L_IN	15.06.25	1000-140 = 860	1070
End production (consume)	5L_IN	29.09.23	0	860	Successful production
End production (consume)	5L_IN	15.06.25	860	860	Successful production
