• What is the cause and solution for SAP error message SRFAC_IMPL026 - Source contains assigns to field symbols! Extraction is impossible. ?

  The SAP error message SRFAC_IMPL026 indicates that there is an issue with the extraction of data due to the presence of field symbols in the source code. Field symbols in ABAP are used as placeholders for data objects, and they can point to different data types at runtime. However, when it comes to data extraction, especially in the context of SAP's data extraction tools (like SAP BW or data services), the system cannot handle field symbols effectively, leading to this error.
  Cause:
  The error occurs because the source code contains assignments to field symbols, which complicates the extraction process. The extraction tools require a clear and static definition of the data structure, which field symbols do not provide since they can change dynamically.
  Solution:
  To resolve this error, you need to modify the ABAP code to eliminate the use of field symbols in the context of the data extraction. Here are some steps you can take:
  
  
  Identify the Field Symbols: Locate the part of the code where field symbols are being used. Look for statements like ASSIGN or FIELD-SYMBOLS.
  
  
  Replace Field Symbols: Replace the field symbols with concrete data types or structures. This may involve creating specific data structures that can be used directly instead of using field symbols.
  
  
  Static Data Types: Ensure that the data types used in the extraction are static and well-defined. This will help the extraction process to understand the data structure without ambiguity.
  
  
  Testing: After making the changes, test the extraction process to ensure that it works without errors.
  
  
  Documentation: Document the changes made to the code for future reference and to help other developers understand the modifications.
  
  
  Related Information:
  
  
  Field Symbols: In ABAP, field symbols are declared using the FIELD-SYMBOLS statement and are assigned to data objects using the ASSIGN statement. They are useful for dynamic programming but can lead to complications in static contexts like data extraction.
  
  
  Data Extraction: SAP provides various tools for data extraction, including SAP BW, SAP Data Services, and others. Each of these tools has specific requirements for the data structures they can work with.
  
  
  ABAP Development Guidelines: Following best practices in ABAP development can help avoid such issues. This includes using clear and static data definitions, avoiding dynamic programming where possible, and adhering to SAP's guidelines for data extraction.
  
  
  By addressing the use of field symbols in your ABAP code, you should be able to resolve the SRFAC_IMPL026 error and successfully perform the data extraction.
