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

SAP Error Message - Details

• 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.

• What is the cause and solution for SAP error message WA642 - Type linkage between & & and &: Entry exists with other secondary data ?

  Certainly! Here's a detailed explanation of the SAP error message:
  
  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 stored for the linkage.
  
  
  2. Explanation of the Message Variables
  
  & placeholders represent the involved object types or categories.
  The message indicates that a linkage between these types already exists but with different secondary data.
  
  
  3. Solution
  To resolve this error, you should:
  
  
  Check Existing Linkages:
  
  Review the existing type linkages between the involved object types.
  Use the relevant customizing transaction or master data maintenance transaction to display existing linkages.
  
  
  
  Compare Secondary Data:
  
  Identify the secondary data associated with the existing linkage.
  Compare it with the data you are trying to enter.
  
  
  
  Decide on Action:
  
  If the existing linkage is correct and should not be changed, avoid creating a duplicate or conflicting entry.
  If the new linkage is required, you may need to delete or modify the existing linkage first.
  Ensure consistency in secondary data for the linkage.
  
  
  
  Use Correct Transactions:
  
  For equipment and functional location categories, check customizing under:
  
  SPRO ? Plant Maintenance and Customer Service ? Maintenance and Service Processing ? Maintenance and Service Orders ? Functions and Settings for Order Types ? Define Object Linkages
  
  
  Or use transaction codes like OIOA (for object linkages).
  
  
  
  Consult Documentation or SAP Notes:
  
  Sometimes, specific SAP Notes address issues related to type linkages and secondary data conflicts.
  
  
  
  
  4. Additional Related Information
  
  
  Type Linkage:
  
  Type linkage in SAP PM (Plant Maintenance) or CS (Customer Service) defines how different object types relate to each other, e.g., how equipment categories link to functional location categories.
  
  
  Secondary Data:
  
  Secondary data can be additional attributes or classifications that further specify the linkage.
  
  
  Impact:
  
  Incorrect or conflicting type linkages can cause issues in master data consistency, reporting, and processing of maintenance orders or notifications.
  
  
  Debugging:
  
  If unsure, you can debug or check the database tables related to type linkages, such as IOTYPELINK or similar, depending on your SAP version.
  
  
  
  Summary
  
  
  
  Aspect
  Description
  
  
  
  
  Cause
  Attempt to create a type linkage that conflicts with an existing linkage having different secondary data.
  
  
  Solution
  Review and correct existing linkages; ensure secondary data consistency; delete or modify conflicting entries.
  
  
  Related Info
  Type linkages define relationships between object types; secondary data must be consistent; check customizing and SAP Notes.
