• What is the cause and solution for SAP error message RSDF_GENERATOR009 - InfoObjects can only be used once ?

  The SAP error message RSDF_GENERATOR009 indicates that there is an issue with the use of InfoObjects in a DataSource or transformation. Specifically, this error occurs when an InfoObject is being used more than once in a context where it is only allowed to be used once. This typically happens in the context of DataSource definitions, transformations, or when creating InfoProviders.
  Cause:
  
  Duplicate Usage: The most common cause of this error is that the same InfoObject is being referenced multiple times in a DataSource or transformation. For example, if you have defined an InfoObject in a transformation and then try to use it again in the same transformation or in another transformation that is linked to the same DataSource, you will encounter this error.
  Incorrect Mapping: If you are mapping fields in a transformation and mistakenly map the same source field to multiple target fields, this can also trigger the error.
  DataSource Configuration: In the configuration of a DataSource, if the same InfoObject is included in multiple places where it should only appear once, this error will occur.
  
  Solution:
  
  Check for Duplicates: Review the DataSource or transformation where the error is occurring. Look for any InfoObjects that are being used more than once. Remove or adjust the duplicate references.
  Adjust Mapping: If the error is related to a transformation, ensure that each source field is mapped to a unique target field. If you need to use the same data in multiple places, consider creating a new InfoObject or using a different approach to achieve your goal.
  Review DataSource Configuration: Go through the DataSource configuration and ensure that each InfoObject is only defined once. If you find duplicates, remove or consolidate them as necessary.
  Testing: After making changes, test the DataSource or transformation to ensure that the error is resolved and that the data is being processed correctly.
