Once you have maintained building units, the hierarchy relationship between the building units, their facilities and planning characteristics and the relationships to the organizational units (OUs), you have to release the building structure. This involves the system checking that the hierarchy structure is consistent. For each correct building structure, the system sets the release indicator in the master data of the building unit.

You can only use released building units in subsequent functions.

In response to the release operation, the system outputs a release log. If errors occurred, this log records the reason for the various errors and the identification key of the building units which could not be released. Building units which have not been released and building units subordinate to these building units in the hierarchy cannot be used in subsequent functions.

The system cancels the release indicator if you make the following changes to building units which have already been released:

• Change to the validity
• Change to the building hierarchy
• Change to the assignment of building units to OUs
• Change to the facilities
