Using this function, the assignments between posting addresses and the corresponding budget addresses are saved as index entries. The system always creates the index entries automatically when you create posting addresses. When the index entries for posting addresses are created, the corresponding budget addresses are saved on the basis of the assigned derivation strategy for budget addresses.

Note that if a change is made to the derivation strategy for budget addresses this does not automatically mean that the corresponding index entries are adjusted. Once you change the derivation strategy for budget addresses, this can cause inconsistencies with the index entries stored in the database. Inconsistency in index entries occurs if the index entries are different to the current assignments (derived in accordance with the current derivation strategy) of posting addresses to budget address.

The index entries provide important information on the following functions of the budget control system:

Changes to master data can also cause budget or actual/commitment to occur in FM account assignments which are not posting or budget addresses according to the current budget structure. The checks for inconsistent data can be carried out using the programs Display Inconsistent Posting Data or Display Inconsistent Budget Data.

You carry out the check for inconsistent index entries, the reconstruction of index entries and the check for inconsistent budget or posting data in the Funds Management menu under Master Data ® Tools ® Budget Structure (Budget Control System) ® Index.
