How To Fix WS561 - You reconstruct the extraction structures in SAP BW (see long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: WS - Supplier Billing Document

• Message number: 561

• Message text: You reconstruct the extraction structures in SAP BW (see long text)

What causes this issue?

You are reconstructing extraction structures for SAP Business
Information Warehouse.

System Response

Confirm the security dialog that appears.

How to fix this error?

The extraction structures function without versions. It is therefore
important that you only reconstruct the extraction structures if the
InfoCubes in SAP BW do not contain any data. If the InfoCubes do
contain data, it will be posted more than once and the key figures will
become too large.
Check the contents of your InfoCubes.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message WS561 - You reconstruct the extraction structures in SAP BW (see long text) ?

  Certainly! Here's a detailed explanation for the SAP error message WS561 related to reconstructing extraction structures in SAP BW:
  
  SAP Error Message WS561
  Message Text:
  
  You reconstruct the extraction structures in SAP BW (see long text).
  
  Cause
  This error message typically occurs when there is a mismatch or inconsistency between the extraction structures defined in the source system (e.g., SAP ERP) and those in the SAP BW system. It often arises during data extraction or when activating data sources in BW.
  Common causes include:
  
  The extraction structures in the source system have been changed or updated (e.g., fields added, removed, or data types changed).
  The extraction structures in BW are outdated or not synchronized with the source system.
  Transport or system copy issues where extraction structures were not properly transported or activated.
  Incomplete or failed activation of the data source or extraction structures in BW.
  
  
  Explanation (Long Text)
  The long text of message WS561 usually advises that the extraction structures in SAP BW need to be reconstructed to align with the current definition in the source system. This means that the metadata in BW must be updated to reflect the current structure of the data source.
  
  Solution
  To resolve the WS561 error, follow these steps:
  
  
  Reconstruct Extraction Structures in SAP BW:
  
  Go to transaction RSA1 (Data Warehousing Workbench).
  Navigate to the Data Sources section.
  Find the relevant data source that is causing the issue.
  Right-click on the data source and select Reconstruct Extraction Structures.
  This action will synchronize the extraction structures in BW with those in the source system.
  
  
  
  Activate the Data Source:
  
  After reconstruction, activate the data source in BW.
  Ensure that the activation in the source system (e.g., via transaction RSA6 or relevant source system transaction) is also completed.
  
  
  
  Check and Transport Objects:
  
  If you are working in a multi-system landscape, ensure that the reconstructed extraction structures and activated data sources are properly transported to the target systems.
  
  
  
  Verify Extraction:
  
  After reconstruction and activation, test the data extraction process to confirm that the error is resolved.

  RSA3 – Extractor Checker (test data extraction)
  
  
  
  Notes:
  
  Always ensure that the source system and BW system are in sync regarding extraction structures.
  Changes in the source system extraction structures require corresponding updates in BW.
  Reconstruction does not delete data but updates metadata structures.
  If custom fields or enhancements are involved, verify that these are correctly handled during reconstruction.
  
  
  
  Common Scenario:
  
  After an upgrade or transport of new extraction structures, WS561 may appear if BW metadata is not updated.
  
  
  
  
  Summary
  
  
  
  Aspect
  Description
  
  
  
  
  Cause
  Mismatch between source system extraction structures and BW metadata.
  
  
  Solution
  Reconstruct extraction structures in BW via RSA1, then activate the data source.
