• What is the cause and solution for SAP error message RSDD_LM096 - Key figures cannot be joined: field &1, provider '&2' (alias &3) ?

  The SAP error message RSDD_LM096 indicates that there is an issue with joining key figures in a query or data model. This error typically arises when the system attempts to join key figures that are not compatible due to various reasons, such as data type mismatches, aggregation issues, or incorrect configurations in the InfoProvider.
  Cause:
  
  Data Type Mismatch: The key figures being joined may have different data types (e.g., one is a currency and the other is a number).
  Aggregation Level: The key figures may be aggregated at different levels, making it impossible to join them directly.
  Incorrect InfoProvider Configuration: The InfoProvider may not be set up correctly to allow for the joining of these key figures.
  Missing or Incorrect Relationships: There may be missing relationships or incorrect joins defined in the data model that prevent the key figures from being joined.
  
  Solution:
  
  Check Data Types: Ensure that the key figures you are trying to join have compatible data types. If necessary, convert them to a common type.
  Review Aggregation Levels: Verify that the key figures are aggregated at the same level. If they are not, consider adjusting the aggregation settings or using a different approach to combine the data.
  Inspect InfoProvider Configuration: Review the configuration of the InfoProvider to ensure that it is set up correctly to allow for the joining of the key figures. This may involve checking the underlying data model and relationships.
  Adjust Query Design: If you are working with a query, consider redesigning the query to avoid joining incompatible key figures. You may need to create calculated key figures or use different InfoProviders.
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance on the key figures and InfoProviders you are working with.
