• Message text: Runtime of transformation rule &1 is not valid

What causes this issue?

While executing transformation rule &V1& (ID &V2&) it was observed that
the runtime object is not valid. Several reasons are possible:
You did not generate the runtime object (source code) at all
You subsequently changed the transformation rule after the runtime
object was already successfully generated
Each subsequent change (such as, renaming the transformation rule,
changing the signature or adapting the source code of a source code
rule) needs to be finalized with a new generation of the runtime object

System Response

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?

Check the transformation rule with the transformation rule editor and
generate the runtime object. Afterwards, execute the erroneous activity
again.
