There are two types of structure relations in ProStructure:
Changing: Adjustment / Synchronization / Maintenance of the target structure
The target structure can be maintained in ProStructure and then applied to the SAP structures.
ProStructure internally own structure data is held
Comparative: a comparison of two structures and the display of differences
Two existing structures are compared
No ProStructure specific data is held
With a comparison, for example:
A structure with two different validities can be compared
A structure can be compared to different organizational units
Two arbitrary structures can be compared
In both cases, the structure comparison and the checks defined for it are always performed and displayed when the relation is opened.
