• What is the cause and solution for SAP error message /SAPAPO/PPM_MAINTAIN520 - Setup act. &1 &2 contains a prim. res. (mode &3) not equal to type SINGLE ?

  The SAP error message /SAPAPO/PPM_MAINTAIN520 typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with the setup activities in production planning. This error indicates that there is a primary resource (mode) associated with a setup activity that is not of type "SINGLE." 
  Cause:
  
  Resource Configuration: The primary resource defined for the setup activity is configured in a way that does not match the expected type. In this case, the system expects a resource of type "SINGLE," but it has found a resource of a different type (e.g., "MULTI" or "GROUP").
  Setup Activity Definition: The setup activity may have been defined incorrectly, leading to a mismatch between the resource type and the expected configuration.
  Planning Object Structure: The planning object structure may not be aligned with the resource definitions, causing inconsistencies.
  
  Solution:
  
  Check Resource Type: Verify the configuration of the primary resource (mode) associated with the setup activity. Ensure that it is set to type "SINGLE." You can do this by navigating to the resource master data in the SAP system.
  Adjust Setup Activity: If the resource type cannot be changed to "SINGLE," consider adjusting the setup activity to use a different resource that is compatible with the expected type.
  Review Configuration: Review the configuration of the setup activities and resources in the APO system to ensure they are correctly defined and aligned with each other.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on configuring resources and setup activities correctly.
  Testing: After making changes, test the setup activity again to ensure that the error is resolved.
  
  Related Information:
  
  Resource Types: In SAP APO, resources can be defined as SINGLE, MULTI, or GROUP, each serving different purposes in production planning.
