Plant as vendor

Question

Hi friends,
In some documentations, I am finding that SAP has recommended to create the plant as vendor to carry out stock trasport order.
But I am able to do stock transport order without defining the plant as vendor also.
My questions are
1. In which scenario(s) is it mandatory to create plant as vendor ?
2. Is there any advantage or disadvantage if I create plant as vendor even if it is not mandatory ?
Thanks in advance.

Answer 1

Not sure how you have mapped the scenario. In my view, the STO process is as follows :
1. Create a vendor for the Company code of the receiving plant using account group 0007 via T-Code XK01.
2. In the purchasing data view assign the supplying plant and the schema group.
3. Create customer with the sales area of the vendor.
4. The shipping conditions, the delivering plant and the transportation zone determine the route in the STO.
5. In the pricing procedure determination relevant to the STO assign document pricing procedure and customer pricing procedure to get the pricing in the invoice.
6. Maintain condition records for pricing condition.
7. Maintain carrier as a partner in the customer master.
8. In OMGN select the supplying plant and assign the company code and sales area. Similarly select the receiving plant and assign the company code and sales area (The company code to which the plant is assigned to).
9. Assign the delivery type and checking rule to the document type.
10. And finally, assign the purchasing document type to the supplying plant and the receiving plant.
11. Create the STO using T-Code ME 21N and save.
12. Check for release strategy if any and release using T-Code ME 28.
13. Create delivery in background using VL10G.
14. If delivery is created, it is an indication of correct configuration and master data creation.
In case : it is done using simple goods issue/ receipt, the proper accounting wouldn't take place (including taxes)
