MRP for project

38 Views

Dear Experts,

I have a structure following:

WBS 1

- Acticity 1

WBS 2

- Activity 2

-- Component T-20000 | 30 (Requirement Quantity) | Requirement day : 10/11/2010

WBS 3

- Activity 3

-- Component T-20000 | 50 (Requirement Quantity) | Requirement day : 14/11/2010

I use WBS group (value=2) for WBS 1. After that i assigned WBS 2,3 into WBS 1 Group. I assigned MRP Group 0010 into WBS 1 Group.

After release project, the system generate 2 reservation for component of 2 different activity. Next step, I run MRP for WBS 1, the system generate 1 planned order for all OrdRes. After that, i run MD04 to check material stock, the result:

Stock: 0

ProjStock : WBS 1 | Available Quantity: 70

OrdRes 2 (WBS 2) | Requirement Quantity :30 | AvaiQty: 40

OrdRes 3 (WBS 3) | Requirement Quantity :50 | AvaiQty: 10-

ProjStock : WBS 2 | Available Quantity: 10

Then i converted PR to PO and GR. Result that system GR (Qty:80) that material into Project Stock (WBS1). Then i transfered posting material (Qty:10) from Project Stock WBS1 to ProjectStock WBS2.

I run MRP again for Project Definition. Result that system gererate additional 1 planned order (qty: 10)

Stock: 0

ProjStock : WBS 1 | Available Quantity: 70

OrdRes 2 (WBS 2) | Requirement Quantity :30 | AvaiQty: 40

OrdRes 3 (WBS 3) | Requirement Quantity :50 | AvaiQty: 10-

PlanOder | Requirement Qty: 10

ProjStock : WBS 2 | Available Quantity: 10

So, problem is that when i run the second MRP, the system didn't take material from ProjStock WBS2.

Kindly explain that problem for my project.

Thank and Best Regards,

NhatLQ
