• What is the cause and solution for SAP error message RSAOLTP004 - Transferred field list is empty ?

  The SAP error message RSAOLTP004, which states "Transferred field list is empty," typically occurs in the context of data extraction processes, particularly when using the SAP DataSource for extracting data from an OLTP (Online Transaction Processing) system to a data warehouse or other reporting tools.
  Cause:
  The error usually arises due to one of the following reasons:
  
  
  No Fields Selected: The field list that is supposed to be transferred is empty, meaning that no fields have been selected for extraction in the DataSource configuration.
  
  
  Incorrect DataSource Configuration: The DataSource may not be properly configured, leading to an empty field list.
  
  
  Authorization Issues: The user executing the extraction may not have the necessary authorizations to access the fields in the DataSource.
  
  
  Technical Issues: There may be technical issues with the DataSource or the underlying table, such as missing data or incorrect table joins.
  
  
  Filter Conditions: If there are filter conditions applied that result in no data being selected, this could also lead to an empty field list.
  
  
  Solution:
  To resolve the RSAOLTP004 error, you can take the following steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP system and verify that the fields you want to extract are selected.
  Ensure that the DataSource is properly configured and activated.
  
  
  
  Review Field Selection:
  
  In the DataSource, check the field selection settings. Make sure that at least one field is marked for extraction.
  
  
  
  Authorization Check:
  
  Ensure that the user executing the extraction has the necessary authorizations to access the DataSource and its fields.
  
  
  
  Test DataSource:
  
  Use transaction code RSA3 to test the DataSource. This will allow you to see if data can be extracted successfully and if the field list is populated.
  
  
  
  Check for Filters:
  
  Review any filters applied to the extraction process. If the filters are too restrictive, they may result in no data being selected.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the extraction process to identify where the field list is being cleared or not populated.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource you are using for any known issues or additional configuration steps.
