No PO committed value in the report S_ALR_87013558

Dear all,

could you help me on the following issue?

There are two kinds of POs in the project.

1. materials assign to the internal activity, run MRP, get PR, and then create the PO for material from the PR.

2. release the service activity and get the service PR and generate the PO from serivce PR.

i check the report S_ALR_87013558 and find that the committed value only contains the service PO values, but no value from the material PO.

please give me some suggestions and advice.

thanks a lot.

Judy
