• What is the cause and solution for SAP error message LTR_PRESEL016 - Preselection path stopped since predecessor step produced no results ?

  The SAP error message LTR_PRESEL016 indicates that a preselection path in a data transfer process (DTP) has been stopped because the predecessor step did not produce any results. This typically occurs in the context of data extraction or loading processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  
  No Data Available: The most common cause is that the source data (e.g., from an InfoProvider or a data source) does not contain any records that meet the selection criteria defined in the DTP.
  Incorrect Selection Criteria: The filters or selection criteria applied in the DTP may be too restrictive, leading to no data being selected.
  Data Load Issues: There may have been issues in previous data load processes that resulted in no data being available for the current step.
  Data Source Configuration: The data source may not be properly configured or may not be active, leading to no data being fetched.
  Technical Issues: There could be technical issues such as connectivity problems, authorization issues, or system performance problems.
  
  Solution:
  
  Check Source Data: Verify that there is data available in the source system that meets the selection criteria. You can do this by running a query or checking the data in the source InfoProvider.
  Review Selection Criteria: Examine the selection criteria in the DTP to ensure they are not too restrictive. Adjust them if necessary to allow for more data to be selected.
  Check Previous Steps: Investigate the previous steps in the data flow to ensure that they executed successfully and produced the expected results. If there were errors, resolve them first.
  Data Source Configuration: Ensure that the data source is correctly configured and active. Check for any changes that may have been made to the data source or InfoProvider.
  Monitor System Performance: Check for any system performance issues or connectivity problems that may be affecting data retrieval.
  Run a Test Load: If possible, run a test load with simplified criteria to see if data can be fetched successfully.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to monitor and manage data flows and DTPs.
  Logs and Traces: Check the logs for the DTP execution to get more details about why the predecessor step did not produce results. You can find logs in the DTP monitor.
  SAP Notes: Look for relevant SAP Notes that may address specific issues related to this error message or provide patches and updates.
  Documentation: Refer to SAP documentation for best practices on configuring DTPs and troubleshooting data load issues.
