• What is the cause and solution for SAP error message WRF_BW_EXTRACTION006 - First start XPRA for LO extract structure changes ?

  SAP Error Message:
  
  WRF_BW_EXTRACTION006 First start XPRA for LO extract structure changes
  
  Cause:
  This error occurs when there are changes in the structure of the Logistics (LO) DataSource extract structure in SAP BW, and the extraction process requires the activation of the extraction structure in transaction XPRA before data can be extracted or loaded.
  In other words, the extract structure has been modified (e.g., fields added, removed, or changed), and the system expects you to activate these changes in XPRA to ensure the extraction logic is consistent with the new structure.
  
  Explanation:
  
  XPRA is the transaction used to activate and manage extract structures for Logistics DataSources.
  When you make changes to the LO DataSource structure (e.g., via customizing or enhancement), these changes are not automatically activated.
  Until you activate the extract structure in XPRA, the extraction process cannot proceed, hence the error message.
  
  
  Solution:
  
  
  Run transaction XPRA:
  
  Go to SAP GUI and enter transaction code XPRA.
  
  
  
  Select the relevant LO DataSource:
  
  In XPRA, find the DataSource for which the structure has changed.
  
  
  
  Activate the extract structure:
  
  Activate the extract structure by choosing the appropriate option (usually a button like "Activate" or "Generate").
  This will regenerate the extract structure and activate the changes.
  
  
  
  Check for any errors during activation:
  
  If activation fails, check the error messages and resolve any issues (e.g., missing fields, inconsistent structures).
  
  
  
  Re-run the extraction:
  
  After successful activation, restart the extraction process.
  
  
  
  Additional steps (if needed):
  
  If you are using delta extraction, you might need to reset the delta or initialize the extraction again.
  Check if any transport requests are required to move the activated structure to other systems (e.g., from DEV to QA/PRD).
  
  
  
  
  Related Information:
  
  Transaction XPRA is specifically for LO DataSources (Logistics extractors).
  This error is common after system upgrades, support package implementations, or manual changes to DataSource structures.
  Always ensure that after any structural changes to LO DataSources, XPRA activation is performed.
  For other types of DataSources (e.g., FI, CO), different activation procedures may apply.
  If you are unsure about the changes, consult the SAP BW or LO consultant responsible for the DataSource.
  SAP Notes and documentation related to LO DataSource extraction and XPRA can provide additional guidance.
  
  
  Summary:
  
  
  
  Aspect
  Details

  LO DataSource extract structure changed but not activated in XPRA.
  
  
  Solution
  Run transaction XPRA ? select DataSource ? activate extract structure ? re-run extraction.
  
  
  Related Info
  XPRA is used for LO DataSource structure activation; required after structural changes.
