How To Fix WLC_PARALLEL042 - Syntax error &1 in the generated selection routines in line &2 (&3)

SAP Error Message - Details

• Message type: E = Error

• Message class: WLC_PARALLEL - Load Distribution and External Parallel Processing

• Message number: 042

• Message text: Syntax error &1 in the generated selection routines in line &2 (&3)

What causes this issue?

To estimate the scope of the worklist, routines are generated that
access the database. According to your settings, the program routines
and database read commands are to be adjusted in line with Customizing
and the entries on your selection screen.
The situation resulting from your entries is not supported by the
current version of the program. This means that data preselection
cannot be carried out generically unless you change the entries.
As a rule, the keys of the tables that are selected and linked with
each other are different. The dependent tables must have the same key
fields (name and type/category) as the table that was read first. You
can have more, but not fewer, key fields than this table has.
When read routines were generated, there were insufficient checks for
your entries, so the error was only discovered indirectly in the syntax
check.

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

How to fix this error?

Analyze the generated routines that are listed in the log if you choose
the option "Output gen. selections?".
Change the information in Customizing and/or the entries on the
selection screen, particularly the selected radio buttons, that is to
say, the selection option to be filled and the field for creating the
parallel jobs.
It often helps to specify the field for job creation itself if the
table of the selection option is not suitable.
If this is not successful, you have to create your own function module
for data preselection. As a reference, use WLC_PRESELECT_EXAMPLE and
the routines included in the log.

• What is the cause and solution for SAP error message WLC_PARALLEL042 - Syntax error &1 in the generated selection routines in line &2 (&3) ?

  The SAP error message WLC_PARALLEL042 indicates that there is a syntax error in the generated selection routines, specifically in the context of parallel processing. This error typically arises when there is an issue with the way the selection routines are defined or generated in the context of a parallel processing job.
  Cause:
  
  Incorrect Syntax: The most common cause is that there is a syntax error in the code that is generated for the selection routines. This could be due to incorrect field names, data types, or logical expressions.
  Data Type Mismatch: If the data types of the fields being used in the selection criteria do not match the expected types, it can lead to syntax errors.
  Missing or Incorrect Parameters: If required parameters for the selection routines are missing or incorrectly defined, it can lead to this error.
  Custom Code Issues: If there is custom code involved in the selection routines, any errors in that code can also lead to syntax errors.
  
  Solution:
  
  Check the Selection Criteria: Review the selection criteria defined in the job or program that is generating the error. Ensure that all field names and data types are correct.
  Debugging: Use the debugging tools in SAP to step through the code and identify the exact line where the syntax error occurs. This can help pinpoint the issue.
  Review Custom Code: If there is any custom code involved, review it for syntax errors or logical issues. Ensure that it adheres to SAP standards.
  Re-generate Selection Routines: If the selection routines were generated automatically, try re-generating them to see if the issue persists.
  Consult Documentation: Check SAP documentation or notes related to the specific transaction or program you are working with for any known issues or updates.
  SAP Support: If the issue cannot be resolved, consider reaching out to SAP support for assistance, providing them with the error details and any relevant context.
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may want to check transaction codes related to the job or program that is generating the error.
  SAP Notes: Search for SAP Notes related to WLC_PARALLEL042 for any patches or updates that may address the issue.
  Parallel Processing: Familiarize yourself with how parallel processing works in SAP, as understanding this can help in troubleshooting related issues.
  
  By following these steps, you should be able to identify and resolve the syntax error indicated by the WLC_PARALLEL042 message.
