Procurement from External Vendor


Hi All:

Our company has a US plant A supplying material X to a plant B, in Asia. We had set it up as intercompany STO. So, when the demand planer ran the product hieuristic for material X in plant B, the PR proposal pointed out to plant A.

The company split. Plant B stayed with the mother company and Plant A was bought by a new company. So, it can no longer be a CC STO. The design is plant B will be customer to plant A and Plant A will be an external vendor to Plant B and plant A has to places a OR1 or OR2 Sales order in Plant B.

To achieve that, I did the following changes.

1. Removed the special procurement key for material X in Plant B that was pointing to Plant A. That took care of the transportation lane between Plant A and Plant B.

2. Deleted the STO link for ZCC in configuration with plant A as the supplying plant and Plant B as the destination plant.

3. Marked the Inforecord of plant vendor (P)A, material X and plant B.

4. Created a inforecord for an external vendor for plant B. This external vendor is a 5 digit vendor code created using ME11 in R3 and is for plant A.

After making sure all these changes CIFed to APO, when I ran the product hieuristics, no PR is created.

The system gives me a message:

The system could neither find a valid transportation lane nor an external procurement relationship.

When I checked what the 'External Procurement Relationship' SAPAPO/PWBSRC1 is about,

I found that this transaction too maintains the relationship between Destination loc Plant 1 with Source location (as plant B and not as Vendor).

Q1. What is the use of the transaction SAPAPO/PWBSRC1?

Q2. Does the system need to created a transportation lane between the plant B that has been defined as an external vendor and Plant A?

Q3. What is that missing that I need to take care of?

Pl. help.
