• What is the cause and solution for SAP error message R8570 - Extraction structure includes invalid field &1 with ABAP type &2 ?

  The SAP error message R8570 indicates that there is an issue with an extraction structure in your SAP system.

This can occur during data extraction processes, such as when using SAP DataSources for data extraction to SAP BW (Business Warehouse) or other data processing tasks.
  Cause
  The error can be caused by several factors:
  
  Invalid Field Type: The field in question may have an ABAP type that is not supported for extraction. For example, certain complex data types or unsupported data types may lead to this error.
  Field Configuration: The field may not be properly configured in the extraction structure, leading to inconsistencies.
  Changes in Data Model: If there have been recent changes to the underlying data model or database table, it may have introduced fields with unsupported types.
  Incompatibility with BW: If the extraction structure is intended for use with SAP BW, certain field types may not be compatible with BW data models.
  
  Solution

  CHAR (Character)
  NUMC (Numeric)
  DATS (Date)
  TIMS (Time)
  DEC (Decimal)
  
  
  
  Remove or Replace the Field: If changing the field type is not feasible, consider removing the field from the extraction structure or replacing it with a different field that has a valid type.
  
  
  Re-activate the DataSource: After making changes, you may need to re-activate the DataSource or the extraction structure to ensure that the changes take effect.
  
  
  Test the Extraction: After making the necessary changes, test the extraction process again to ensure that the error has been resolved.
