SAP SRM reports

Hello everyone,

Presently, I am working on SAP SRM module and would soon be looking at few of the BW reports.

Below are the reports that I was asked to plan on :

1. Report showing how many times a Purchase Order has changed.

2. Purchase Orders that are over 72 hours and haven't been confirmed.

3. Report showing Bill of Materials (BOM)

4. INventory movement report

5. Open RFQs

6. How many Quality Notifications have been assigned to the Suppliers.

7. Negative Balance Report.

Could anyone please let me know if it possible to execute these reports in SAP BW.

Many Thanks,

SR
