[former_member201529]

Objective :

• To run the MRP for multiple plants.
• Same material involving into In-house production, External Procurement, Stock Transport Order and Subcontract process.

Plant Details:

• Plant B (Manufacturing Plant1)
• Plant C (Manufacturing Plant2)
• Plant B1 (Internal Warehouse for Plant1)
• Plant C1 (Internal Warehouse for Plant2)
• Plant A (Distribution plant)

Material Master Settings:

Plant	Plant A	Plant B1	Plant C1	Plant B	Plant C
Material	Test 1	Test1	Test1	Test1	Test1
MRP Type	V1/V2	PD	PD	PD	PD
Reorder Point	1000
Procurement Type	F - External Procurement	F - External Procurement	F - External Procurement	E – In house Production	E – In house Production
Quota	Yes	Yes	Yes

For Plant A:

Demand in Plant A :   

Here ROP = 1000 number is act as  demand.

When we run MRP system generates Stock transfer PR based on percentage given in Quota.

For Plant B1 and C1:

Demand Flow from different plants:

Total Demend in Plant (B and C) = Demand from Plant A + Demand from Plant B1 and C1

MRP Results:

When run MRP for Plant A:

Demand Created for Plant B1 and C1.

When run MRP for B1 and C1:

Create stock transfer dependent requirement from Plant A and create request for Plant B.

Create stock transfer dependent requirement from Plant A and create request for Plant C.

When run MRP for Plant B and C:

• Create stock transfer dependent requirement from Plant A based on Quota and Planned order will create based on Quantity + Dependent requirement from B1 and C1.
• If use any special procurement key for subcontract then SC PR will create based on Quota.
• Create direct PR or Scheduling Lines.
