• What is the cause and solution for SAP error message RSR_EXPLAIN012 - Constant selection will be deactivated for characteristic "&1" (&2) ?

  The SAP error message RSR_EXPLAIN012 indicates that constant selection for a characteristic in a query is being deactivated. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when you are trying to execute a query that involves a characteristic that has been set up in a way that does not allow constant selection.
  Cause:
  The error can be caused by several factors, including:
  
  
  Characteristic Settings: The characteristic in question may not be set up to allow constant selection. This can happen if the characteristic is defined in a way that does not support constant values.
  
  
  Query Design: The query may be designed in such a way that it conflicts with the constant selection feature. For example, if the characteristic is part of a hierarchy or has certain restrictions, constant selection may be disabled.
  
  
  Data Source Issues: The underlying data source (e.g., InfoProvider) may not support constant selection for the characteristic due to its structure or configuration.
  
  
  Query Execution Context: The context in which the query is executed may not allow for constant selection, such as when certain filters or variables are applied.
  
  
  Solution:
  To resolve the RSR_EXPLAIN012 error, you can take the following steps:
  
  
  Check Characteristic Settings:
  
  Go to the characteristic in the SAP BW modeling tools and check its properties. Ensure that it is configured to allow constant selection.
  
  
  
  Review Query Design:
  
  Open the query in the Query Designer and review the settings for the characteristic. Ensure that it is not part of a hierarchy or that there are no conflicting settings that would prevent constant selection.
  
  
  
  Modify Query Filters:
  
  If the query has filters or variables that may conflict with constant selection, consider modifying or removing them to see if that resolves the issue.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific characteristic and its behavior in queries. There may be specific guidelines or limitations that apply.
  
  
  
  Test with Different Data Sources:
  
  If possible, test the query with different InfoProviders or data sources to see if the issue persists. This can help identify if the problem is specific to a particular data source.
  
  
  
  Contact SAP Support:
  
  If the issue cannot be resolved through the above steps, consider reaching out to SAP support for further assistance. They may have additional insights or solutions based on the specific configuration of your system.

  By following these steps, you should be able to identify the cause of the RSR_EXPLAIN012 error and implement a solution to enable constant selection for the affected characteristic.
