• What is the cause and solution for SAP error message RSDD_LM051 - Field '&1' is only linked with constants ?

  The SAP error message RSDD_LM051, which states "Field '&1' is only linked with constants," typically occurs in the context of SAP BW (Business Warehouse) when working with InfoObjects, especially during the process of creating or modifying queries in the Query Designer or when working with data models.
  Cause:
  This error indicates that the field (InfoObject) you are trying to use in your query or data model is not linked to any variable or characteristic that can provide dynamic values. Instead, it is only associated with constant values. This situation can arise due to:
  
  Incorrect InfoObject Configuration: The InfoObject may be configured to only accept constant values, which means it cannot be used in a way that allows for dynamic filtering or selection.
  Query Design Issues: The query may be designed in such a way that it expects a variable or characteristic that can change, but the field in question does not meet this requirement.
  Data Model Limitations: The underlying data model may not support the dynamic use of the field due to its design or the way it is populated.
  
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check InfoObject Settings:
  
  Go to the InfoObject in the SAP BW system and check its properties. Ensure that it is set up to allow for dynamic values and is not restricted to constants only.
  If necessary, modify the InfoObject to allow for variable values.
  
  
  
  Review Query Design:
  
  Open the Query Designer and review the query that is causing the error. Check how the field is being used and ensure that it is appropriately linked to a variable or characteristic that can provide dynamic input.
  If the field is being used in a filter or selection criteria, consider replacing it with a different field that allows for dynamic values.
  
  
  
  Use Variables:
  
  If applicable, create a variable for the field that can accept user input or dynamic values. This can help in making the field more flexible and usable in queries.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to InfoObjects and query design to understand the limitations and configurations that may apply to your specific scenario.
  
  
  
  Testing:
  
  After making changes, test the query or data model again to ensure that the error is resolved and that the desired functionality is achieved.
