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.
