How To Fix PM262 - Loops in the hierarchy structure not allowed

PM262 - Overview

• Message type: E = Error

• Message class: PM - Extended Payment Functions

• Message number: 262

• Message text: Loops in the hierarchy structure not allowed

What causes this issue?

Cash deconcentration occurs within one of the tables corresponding to
one of the header trees: One or more bank accounts have exactly one
superior clearing account. The same applies one level higher: One or
more clearing accounts have exactly one superior clearing account. The
target account is settled on the highest hierarchy level. It is
therefore the clearing account on the highest hierarchy level.
No loops are allowed within this structure as otherwise the algorithm
for the optimization of the account balances runs in an endless loop.
Optimization must always go from the bottom to the target account at
the top of the hierarchy specified.
In this case, such a loop was discovered in the hierarchy. The simplest
loop occurs when the bank account and the corresponding clearing
account are identical.

PM262 - Details

• The SAP error message PM262, which states "Loops in the hierarchy structure not allowed," typically occurs in the context of SAP Plant Maintenance (PM) or SAP Project System (PS) when there is an issue with the hierarchical structure of objects, such as functional locations, equipment, or project structures. This error indicates that there is a circular reference in the hierarchy, which is not permissible in SAP.
  
  Cause:
  
  Circular References: The most common cause of this error is the presence of circular references in the hierarchy. For example, if Functional Location A is assigned to Functional Location B, and Functional Location B is assigned back to Functional Location A, this creates a loop.
  Incorrect Hierarchical Structure: The hierarchy may have been incorrectly defined, leading to loops that violate the structural integrity required by SAP.
  Data Migration Issues: If data has been migrated from another system, it may have introduced inconsistencies or loops in the hierarchy.
