Hello Experts,
I have come across an issue relating to Project Material Demands, which I am not sure if it is the expected IFS behavior or a defect in the system.
Please consider this scenario, I have a Part 240-10042, of which 10 units are available in the ‘Project Inventory’.

I have created a Project Material Demand using the “Project Material and Services” page for the same part for 15 units and ‘supply option’ = ‘PMRP’. Then i go on to create a ‘reservation’.

Upon clicking the ‘Reserve’ command, I get an information message indicating that all 15 parts couldn’t be allocated, but system ‘Reserves’ 10 available units against the Project Demand.

This creates a record in ‘Inventory Part in Stock Reservations’ in the system.

However, when i check the ‘Inventory Plan Availability Planning” page, expectation was to see ‘5 units’ registered in the ‘Short’ column. But ‘Short’ column shows a zero.

On the other hand, If I create a Material Requisition for the same part and for the same required quantity 15 when available qty is again 10, system registers a ‘Short’ of 5 units.

See the “Inventory Part Availability Planning’ screen that shows ‘No’ Short against the ‘Project Demand” based reservation’ and the ‘5 unit’ short registered against ‘Material Requisition’ based reservation.

Is this a defect in the system or the expected behavior, but for me it doesn’t make sense why IFS doesn’t register a ‘short’ against the project demand in former scenario.
Moreover, here’s the ‘field description’ for ‘Short’ column which made me think that i should be seeing a qty of 5 under that.
“The shortage quantity, displayed in the inventory unit of measure. A shortage quantity will arise when you reserve parts for an order and there is not enough available quantity. It is the difference between the quantity of demanded parts and the reserved parts. A prerequisite is that the shortage notification functionality is activated in the system and on the specific inventory part.”
Note that i have enabled the ‘shortage notification’ both at the system level and at the part level and used the same part for both scenarios.
Thanks for your support.
Cheers!
