GK527
- Relationships of hierarchy levels &1 and &2 are reciprocal ?The SAP error message GK527, which states "Relationships of hierarchy levels &1 and &2 are reciprocal," typically occurs in the context of hierarchical data structures, such as those used in SAP's Controlling (CO) module or other areas where hierarchical relationships are defined.
Cause: This error arises when there is a reciprocal relationship defined between two hierarchy levels. In other words, if level A is defined as a parent of level B, and level B is also defined as a parent of level A, this creates a circular reference, which is not allowed in hierarchical structures. This can happen due to: Incorrect Hierarchy Configuration: The hierarchy levels have been incorrectly set up, leading to a circular relationship. Data Entry Errors: Manual entry errors when defining relationships between hierarchy levels. System Migration Issues: If data has been migrated from another system, it may have introduced inconsistencies in the hierarchy relationships.
