Subcontracting PO reversal issue

143 Views

Dear All,

I have observed an issue when i do subcontracting PO reversal via MIGO. Following are the settings i have defined and the process i have executed for the same.

1. Spro - Production > Material Requirements Planning> Master Data> Define Special Procurement Type

Defined Special prourement type (SP Type 30 subcontracting at plant level)

Maintained Procurement type : X and Special procurement L

2. Material Master

In MRP2 view maintained Procurement Type X and Special Procurement 30

Since our process is based on Sales Order / Line item , i am doing a work around where i transfer the materials attached to the subcontracting material to a temporary storage location and then create the Subcontracting PO.

Eg: Subcontracting Material A - Subcontracting PO created

Material B attached to Subcontracting Material A - Transfered from location STA to STB

3. Upon confirmation of Stock for Material B (which initially had plan orders that are converted to Production order and eventually

converted to stock) i GRN the subcontracting PO.

The storage location i refer in MIGO screen for the Material B (Which is attached to the subcontracting material A) is STB

The GRN happens successfully where 101 movement happens for the subcontracting material A and 543 happens for the material

B

Problem : When i try to reverse the GRN via MIGO 102, i get a message stating "Deficit of Sales order st. unr. 100 EA : Material B Plant storage location Batch Number E (Original message : Deficit of Sales order st. unr. 100 EA :CBEMBTEST-1BLK 7200 7201 0001472595 E)

But when i do a material cancelation i dont get this problem, what could be the reason for this to happen.

Why would there would a deficit of sales order stock for a material where i am bringing back stock into the system. Is there some configs that i have to look into or is it the standard SAP behaviour.

Highly appreciate an urgent assistance
