  The SAP error message UMC050, which states "The selected value fields use different data sources," typically occurs in the context of SAP BusinessObjects or SAP BW when you are trying to create a report or query that involves multiple value fields that are sourced from different data sources. This can lead to inconsistencies and conflicts in the data being retrieved.
  Cause:

  Check Data Sources: Review the data sources of the value fields you are trying to use. Ensure that they are from the same InfoProvider or compatible data sources.
  Use a Single Data Source: If possible, modify your query or report to use fields from a single data source. This may involve redesigning the query or using a different InfoProvider that contains all the necessary fields.
  Combine Data Sources: If you need to use multiple data sources, consider creating a new InfoProvider that combines the necessary data into a single source. This can be done through data modeling in SAP BW or using a data blending technique in SAP BusinessObjects.
  Check Query Structure: Ensure that the structure of your query is set up correctly. Sometimes, adjusting the way you are pulling in fields or aggregating data can resolve the issue.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance on handling data sources and resolving this error in your particular context.
