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.
