SAP Error Message:
W-088 Assignment not allowed: incorrect hierarchy structure assignment
Cause:
This warning message occurs when you try to assign an object (such as a cost center, profit center, or other master data) to a hierarchy node or structure that is not valid according to the defined hierarchy rules in SAP. Essentially, the system detects that the assignment violates the hierarchy structure, for example:
In SAP controlling and organizational management, hierarchies are used to group and report on master data objects. These hierarchies have strict rules about which objects can be assigned where. If you try to assign an object to a node that is outside the allowed structure, SAP issues this warning.
