Diagnosis
If more than one data supply flow has been created for an accountingview, and the physical InfoCubes for actual data are summarized over amultiprovider, the following applies.

• It is not possible to call up line items from a report on the
multiprovider. Attempting to do so will lead to a system termination.

• It is possible, however, to call up the line item from the individual
InfoCubes (provided that targets have been set accordingly inCustomizing for BW). However, the system then displays all line itemsthat match the report's selection criteria, irrespective of whetherthey are contained in the selection of the InfoPackages with which theInfoCube was provided with data. This means that more line itemsare displayed than expected.

Procedure
Only use more than one data supply flow in exceptional cases - when youdo not want to be able to call up line item reports from BW reports.
Try to make do with just one data supply flow per Accounting View.
