• What is the cause and solution for SAP error message RSDD_LM086 - Provider '&1' (type: &2) cannot be used as a join ?

  The SAP error message RSDD_LM086 indicates that a specific provider (like a DataStore Object, InfoCube, or other data source) cannot be used as a join in a query or a data model. This error typically arises in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when trying to create a query that involves joining multiple data providers.
  Cause:
  The error can occur due to several reasons:
  
  Provider Type: The provider you are trying to use may not support joins. For example, certain types of InfoProviders (like some types of DataStore Objects) may not be designed to be joined with others.
  Incompatible Structures: The structures of the providers being joined may not be compatible. This can happen if the fields you are trying to join on do not match in terms of data types or semantics.
  Query Design: The way the query is designed may not allow for the joining of the specified providers. This could be due to restrictions in the query designer or the specific characteristics of the providers.
  Data Source Configuration: The configuration of the data source may not allow it to be used in a join context.
  
  Solution:
  To resolve the error, consider the following steps:
  
  Check Provider Type: Verify the type of the provider you are trying to use. If it is not a type that supports joins, you may need to redesign your query or use a different provider.
  Review Data Structures: Ensure that the fields you are trying to join on are compatible. Check the data types and ensure that they match.
  Modify Query Design: If the query design is causing the issue, try to simplify the query or change the way you are attempting to join the providers. You may need to use a different approach, such as using a union instead of a join.
  Consult Documentation: Refer to SAP documentation for specific guidelines on the types of providers that can be joined and any limitations that may apply.
  Use Composite Providers: If applicable, consider using Composite Providers, which allow for more flexible data modeling and can often handle joins more effectively.
  Check for Updates: Ensure that your SAP BW system is up to date, as newer versions may have improved capabilities or bug fixes related to joins.
