  The SAP error message WB2B2026 "An incomplete exception is only allowed for table &1" typically occurs in the context of ABAP programming, particularly when dealing with database tables and exception handling in ABAP programs. This error indicates that there is an issue with how exceptions are being defined or handled in relation to a specific database table.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Incomplete Exception Handling: The program is trying to define an incomplete exception for a database table that does not support it. Incomplete exceptions are typically used for certain types of tables, and if the table in question does not allow for this, the error will be triggered.
  Incorrect Table Definition: The table specified in the error message may not be defined correctly in the ABAP Dictionary or may not be compatible with the operation being performed.
  Program Logic Issues: There may be logical errors in the ABAP code that lead to the incorrect handling of exceptions.

  Check Table Definition: Verify the definition of the table specified in the error message. Ensure that it is correctly defined in the ABAP Dictionary and that it supports the type of exception handling you are trying to implement.
  
  
  Review Exception Handling: Look at the ABAP code where the exception is being defined. Ensure that you are using complete exceptions where required and that you are not trying to use incomplete exceptions for tables that do not support them.
  
  
  Modify Code Logic: If the logic in your program is incorrect, modify it to ensure that exceptions are handled appropriately. This may involve changing how you are trying to catch or define exceptions.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on exception handling in ABAP, particularly in relation to the specific table you are working with.
  
  
  Debugging: Use the ABAP debugger to step through the code and identify the exact point where the error occurs. This can provide insights into what might be going wrong.
