  The SAP error message RSDD_LM019 indicates that there is an issue with a data provider (such as a query or a data source) in SAP BW (Business Warehouse) where a field is being added more than once. This typically occurs during the modeling of InfoProviders, such as when creating or modifying a MultiProvider, CompositeProvider, or InfoSet.
  Cause:
  The error is caused by attempting to add the same field (or characteristic) to a provider more than once. This can happen in scenarios such as:
  
  When you are trying to join multiple data sources and one of the fields is already included in the provider.
  When there are duplicate fields in the underlying data sources that are being combined.
  When there is a misconfiguration in the data model or the query definition.
  
  Solution:
  To resolve the RSDD_LM019 error, you can take the following steps:
  
  
  Check the Data Model: Review the data model where the error is occurring. Look for the provider (join) specified in the error message and check the fields being added.

  Checking the field list in the provider definition.
  Reviewing the underlying data sources to see if the same field is included in multiple sources.

  Modifying the join conditions to ensure that the field is only included once.
