You always use an alternative commitment item hierarchy if the hierarchical assigning of operative commitment items of the standard variant does not allow the desired data preparation.

Then you can use alternative hierarchies for evaluation purposes as shown in the graphic below. You can also assign revenues and expenditure items to a joint hierarchy for example – this is not possible in the standard variant.

If you are working in your FM area without a budgeting hierarchy, then the budget distribution must be implemented by an alternative commitment item hierarchy.

For evaluating commitment items of the alternative commitment item hierarchy, you use the logical database FMF.

You can also execute the hierarchy structure in the master record with the function Single Processing and enter the higher-level commitment item in the tab page Alternative Hierarchy.

In contrast to the hierarchy processing of the standard variant, you cannot create new commitment items in the function Change Alternative Hierarchy. You create an alternative commitment item in the single processing. Commitment items, that you use exclusively in alternative commitment item hierarchies, must be flagged as Non-postable in the master data and have the assignment of the respective variant entered on the Alternative Hierarchy tab page.
