How To Fix WA642 - Type linkage between & & and &: Entry exists with other secondary data

WA642 - Overview

• Message type: E = Error

• Message class: WA - Messages from Workflow Event Manager

• Message number: 642

• Message text: Type linkage between & & and &: Entry exists with other secondary data

What causes this issue?

When the specified linkage was entered, it was found that an entry with
this key already exists. However, the entry which already exists has
different secondary data than that currently passed. This means that
one of the following fields has a different value for the existing
entry than that passed in the current call:
CHECKFB (check function module)
RECFB (receiver function module)
RECGETFB (function module for determining receiver type)
GLOBAL (indicator for type linkage)

System Response

The action was terminated. The old entry is not changed, the new entry
was not inserted.

How to fix this error?

Check the call of the function module in your source text. Compare the
values passed (e.g. using the event trace) with the values already
contained in the type linkage table (e.g. using trasaction
<DS:TRAN.SWETYPV>SWETYPV</>). If necessary, delete the old entry and
then try the action again.

  SAP Error Message:
  WA642 Type linkage between & & and &: Entry exists with other secondary data
  
  1. Cause of the Error
  This error occurs in SAP when you try to create or maintain a type linkage between two object types (e.g., equipment categories, functional locations, or other master data types), but there is already an existing entry with different secondary data for the same primary linkage.
  In other words, the system is telling you that a linkage between the specified types already exists, but with different secondary data, and therefore, the new entry you are trying to create conflicts with the existing one.
  Typical scenarios:
  
  When defining linkages between equipment categories or functional location categories.
  When maintaining object type linkages in the system (e.g., in transaction codes like IL01, IE01, or customizing transactions).
  When the secondary data (such as a classification or characteristic) differs from what is already
