What does SAP mean here? Is the following supported?

1) Subcontracting Info Record A (same material, same plant) with Vendor X ... and Subcontracting Info Record B (same material, same plant) with Vendor Y

2) Subcontracting Info Record A (same material, plant K) with Vendor X ... and Subcontracting Info Record B (same material, plant L) with Vendor Y

3) Subcontracting Info Record A (same material, plant K) with Vendor X ... and Subcontracting Info Record A (same material, plant L) with Vendor X
