• What is the cause and solution for SAP error message WLC_PARALLEL028 - Table &1 is not contained in a DATA statement ?

  The SAP error message WLC_PARALLEL028 indicates that a specific table (denoted as &1 in the error message) is not included in a DATA statement within the context of parallel processing. This error typically arises in ABAP programs that utilize parallel processing techniques, such as background jobs or parallel processing frameworks.
  Cause:
  The error occurs when the program attempts to access a table that has not been declared in the DATA statement. In parallel processing, all data structures that are used in the parallel tasks must be explicitly defined to ensure that each parallel task has its own instance of the data.
  Solution:
  To resolve this error, you need to ensure that the table mentioned in the error message is properly declared in the DATA statement. Here are the steps to fix the issue:
  
  
  Identify the Table: Check the error message to identify which table is causing the issue. The table name will be displayed in place of &1.
  
  
  Locate the DATA Statement: Open the ABAP program or function module where the error occurs and locate the DATA statement section.
  
  
  Declare the Table: Add a DATA statement for the table that is missing. For example, if the table is my_table, you would add:
  DATA: my_table TYPE TABLE OF my_table_type.
  
  
  Check Parallel Processing Logic: Ensure that the logic for parallel processing is correctly implemented. Each parallel task should have its own data instance to avoid conflicts.
  
  
  Test the Program: After making the changes, test the program to ensure that the error is resolved and that the program behaves as expected.
  
  
  Related Information:
  
  Parallel Processing in ABAP: Understand the concepts of parallel processing in ABAP, including the use of background jobs, parallel cursor techniques, and the use of the CALL FUNCTION ... STARTING NEW TASK statement.
  Data Declaration: Familiarize yourself with the proper syntax for declaring internal tables and structures in ABAP.
  Debugging: Use the ABAP debugger to step through the code and identify where the error occurs, which can help in understanding the context of the error.
  
  By following these steps, you should be able to resolve the WLC_PARALLEL028 error and ensure that your ABAP program runs correctly in a parallel processing environment.
