• What is the cause and solution for SAP error message D9373 - Cyclic composition not allowed ?

  The SAP error message D9373, "Cyclic composition not allowed," typically occurs in the context of SAP's Product Lifecycle Management (PLM) or when dealing with Bill of Materials (BOM) structures. This error indicates that there is a cyclic dependency in the composition of materials or components, meaning that a component is indirectly or directly referencing itself, which is not allowed in SAP.
  
  Cause:
  
  Cyclic Dependency: The most common cause of this error is that a material or component is included in its own BOM or structure, either directly or through a chain of other components. For example, if Component A includes Component B, and Component B includes Component A, this creates a cycle.
  Incorrect BOM Structure: The BOM may have been incorrectly defined, leading to unintended cyclic references.
  Data Entry Errors: Manual entry errors during the creation or modification of BOMs or material master records can lead to cyclic compositions.
  
  
  Solution:
  
  
  Review BOM Structure: Check the BOM
