Hello Hariprasad,
Assume Plant configuration is in place.
1) Hope Plant A procures Raw materials from external vendor. So, have this vendor created in SAP.
Create a Standard Purchase Order of type NB to procure raw materials from the vendor in ME21N
2) Receiving raw materials from Vendor: Perform Goods receipt for the above purchase order in tcode MIGO. This will bring the raw materials to Plant A Stock.
3) Create Invoice for above external purchase in Tcode MIRO
Now you have the raw material in Plant A. This raw material needs to be transferred to Plant B and Plant C.
Ensure the raw material is extended to Plant B and C as well.
It slightly depends on the scenario. Are these plants B and C assigned to same company code.
If yes, then it is an Intra-company Stock Transfer.
If plant B and C are assigned to different company code. Then the scenario is Inter-company Stock transfer.
a) Intra-company stock transfer.
-->Plant would create a Purchase Order of type UB with Supplying plant as "A" in ME21N. Once the Purchase order is created.
--> Create a Delivery for the Purchase order in VL10B. Make sure the above created Purchase order has Shipping tab. If not, please ensure you have entries in T161W
Supplying plant | Rec plant |Doc type
Plant A Plant B UB
Once delivery is created, pick the delivery and issue the goods.. This will remove the Stock from Supplying plant. And will be available as Stock In transit.
You will have to receive the goods in receiving plant in Tcode MIGO with respect to the outbound delivery.
This again depends on config. in T161W. You can even configure such that GR at receiving plant is posted automatically as the stock is issues from Supplying plant.
same procedure can be followed for plant a- plant c.
b) Intercompany Stock Transfer
-->Create a Plant Vendor for Plant A. And create a Purchase order of type NB.
All the other steps same as Intra company Stock transfer.
