Reconstructing Distributed Values 
Use
You have to reconstruct distributed values in the following cases:
You have made changes to your master data hierarchy, by for example having detached individual nodes or subtrees from the structure and reinserting them at another point in the hierarchy or another subhierarchy. The reconstruction of distributed values ensures that already distributed budget is recalculated according to the changes you have made.
The budget from the nodes split off which has already been distributed and which you have assigned to a different subhierarchy, is then available for distribution again by the original superior nodes. Correspondingly less budget is then available for distribution for the superior nodes in which you have inserted the split off nodes.

If there is not sufficient budget in the superior node to distribute to the nodes which have been added, you must adjust the budget values manually.
If, for example, in an existing

You do not have to reconstruct the distributed values if you have:
Procedure
If you do not enter a version, the system automatically uses version 0.

To improve system performance, reconstruct the distributed values in background processing.
Result
If availability control is active for the specified FM area and specified fiscal year, you must reconstruct the assigned values after totaling up the budget values.
