Diagnosis
When you positioned object &V1& including its subobjects below objectV2, the system had to adjust the status of the objects in thissubtree to reflect their new position.

System Response
In this case, the following activities have been carried out:
IF &V4+0(1)& <> &SPACE&

• Deletion of tenant rental periods

The old higher-level object of &V1& was tenant rented, thus also objectV1 and its subobjects were implicitly tenant rented. this indirecttenant rental no longer exists. The objects of the reassigned subtreehave thus been set to "available" in the previous tenant rentalperiods.
ENDIF
IF &V4+1(1)& <> &SPACE&

• Adding tenant rental periods

The new higher level object &V2& is tenant rented. Consequently theobjects of the assigned subtree are also implicitly tenant rented.
ENDIF
IF &V4+2(1)& <> &SPACE&

• Changed from "Not available" to "Available"

The new higer-level object &V2& is available in periods in which &V1&was previously not available. Since an available object can only haveavailable subobjects, the status of the objects of the reassignedsubtree was adjusted.
ENDIF

Procedure
The above changes were necessary to maintain the formal consistency ofthe availability data. However you should check if you really want tomake a reassignment under these circumstances.
