• What is the cause and solution for SAP error message AXT_RUNTIME_MESSAGES012 - &1 is not a component of the extract structure; enter correct selection ?

  The SAP error message AXT_RUNTIME_MESSAGES012 typically indicates that there is an issue with the data extraction process, specifically that a field or component you are trying to use is not part of the defined extract structure. This can occur in various contexts, such as when working with DataSources, InfoSources, or during the extraction of data from SAP systems.
  Cause:
  
  Incorrect Field Selection: The field you are trying to extract is not included in the extract structure defined for the DataSource.
  Changes in DataSource: If the DataSource has been modified (e.g., fields added or removed) after the extraction process was set up, it may lead to this error.
  Inconsistent Metadata: There may be inconsistencies between the metadata in the source system and the target system (e.g., BW).
  Custom Fields: If you are trying to extract custom fields that were not properly added to the DataSource.
  
  Solution:
  
  
  Check the Extract Structure:
  
  Go to the DataSource in the SAP system (transaction code RSA1 for BW).
  Verify that the field you are trying to extract is indeed part of the extract structure.
  If it is not, you may need to add it to the DataSource.
  
  
  
  Update the DataSource:
  
  If changes were made to the DataSource, ensure that you have activated the DataSource after making changes.
  Use transaction RSA6 to check the DataSource and ensure it is active.
  
  
  
  Recreate the DataSource:
  
  If the DataSource is significantly out of sync, consider recreating it or using the "Replicate DataSource" option to refresh it.
  
  
  
  Check for Custom Fields:
  
  If you are using custom fields, ensure they are properly defined in the DataSource and that they are included in the extract structure.
  
  
  
  Check for Transport Issues:
  
  If the DataSource was transported from one system to another, ensure that all related objects were transported correctly.
  
  
  
  Consult Documentation:
  
  Review any relevant SAP documentation or notes related to the specific DataSource you are working with.
