• What is the cause and solution for SAP error message /SAPAPO/DMRES120 - Recursive definition of references ?

  The SAP error message /SAPAPO/DMRES120 Recursive definition of references typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with the definition of resources or planning objects. This error indicates that there is a circular reference in the definitions of the resources, which can lead to infinite loops or inconsistencies in the planning process.
  Cause:
  The recursive definition of references usually arises from one of the following scenarios:
  
  Circular References: Two or more resources or planning objects reference each other in a way that creates a loop. For example, Resource A might reference Resource B, and Resource B might reference Resource A.
  Incorrect Configuration: Misconfiguration in the resource definitions or planning object settings can lead to unintended circular references.
  Data Integrity Issues: Data inconsistencies or corruption in the master data can also lead to this error.
  
  Solution:
  To resolve the /SAPAPO/DMRES120 error, you can follow these steps:
  
  
  Identify Circular References:
  
  Review the resource definitions and check for any circular references. You can do this by examining the resource relationships in the SAP APO system.
  Use transaction codes like /SAPAPO/RES01 (Resource Overview) to analyze the resource definitions.
  
  
  
  Modify Resource Definitions:
  
  If you find circular references, modify the resource definitions to eliminate the circularity. This may involve changing the way resources reference each other or restructuring the resource hierarchy.
  
  
  
  Check Configuration Settings:
  
  Ensure that the configuration settings for the resources are correct and do not inadvertently create circular dependencies.
  
  
  
  Data Consistency Check:
  
  Run data consistency checks to ensure that there are no integrity issues in the master data. You can use transaction codes like /SAPAPO/DM_CHECK to perform checks on the data.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to resource definitions and planning objects for additional guidance on best practices and configuration.
  
  
  
  Testing:
  
  After making changes, test the resource definitions to ensure that the error no longer occurs and that the planning process functions as expected.
