• What is the cause and solution for SAP error message /SAPTRX/ASC087 - Main table &1 is incompatible with extractor &2 in &3 &4. ?

  The SAP error message /SAPTRX/ASC087 indicates that there is an incompatibility between a main table and an extractor in the context of SAP data extraction. This error typically arises in scenarios involving SAP Data Services, SAP BW (Business Warehouse), or other data extraction processes where data is being pulled from a source system.
  Cause:
  The error message /SAPTRX/ASC087 can occur due to several reasons:
  
  
  Schema Changes: The structure of the main table (e.g., changes in fields, data types, or the addition/removal of columns) has been modified after the extractor was created. This can lead to mismatches between the expected data structure in the extractor and the actual structure of the main table.
  
  
  Version Mismatch: The extractor may be designed for a different version of the main table. If the extractor is not updated to reflect changes in the main table, it can lead to incompatibility.
  
  
  Configuration Issues: Incorrect configuration settings in the extractor or the data flow can also lead to this error.
  
  
  Transport Issues: If the extractor was transported from one system to another (e.g., from development to production), and the main table was not in sync, this error can occur.
  
  
  Solution:
  To resolve the /SAPTRX/ASC087 error, you can follow these steps:
  
  
  Check Table Structure: Verify the structure of the main table (&1) and ensure that it matches the expected structure defined in the extractor (&2). You can do this by comparing the data dictionary definitions.
  
  
  Update Extractor: If there have been changes to the main table, you may need to update the extractor to align with the new structure. This may involve modifying the extractor or creating a new one if necessary.
  
  
  Re-activate the Extractor: Sometimes, simply re-activating the extractor can resolve the issue. This can be done in the SAP BW or Data Services environment.
  
  
  Check for Transport Issues: If the extractor was recently transported, ensure that all related objects (including the main table) were also transported correctly and are in sync.
  
  
  Consult Documentation: Review SAP notes and documentation related to the specific extractor and main table for any known issues or updates.
  
  
  Testing: After making changes, perform tests to ensure that the extractor is functioning correctly and that data can be extracted without errors.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific guidance or patches related to the error message.
  Data Dictionary: Use transaction codes like SE11 to view the data dictionary and check the structure of the main table and extractor.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA3 (for testing extractors) and RSA1 (for data warehousing workbench) to troubleshoot and manage extractors.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or BW team for further assistance.
