How To Fix CNV_PE_GEN125 - For client field &1 a transformation is already defined

CNV_PE_GEN125 - Overview

• Message type: E = Error

• Message class: CNV_PE_GEN - Messages for object generation

• Message number: 125

• Message text: For client field &1 a transformation is already defined

What causes this issue?

For the client field &V1& (type CLNT) a user-defined transformation is
present.

System Response

For each structured parameter (for example, T_ACCIT) of the transfer
method function module the transformation rule
_PE_GET_CLIENT_OF_RFC_SYSTEM is automatically added to the client field
(first field within the structured parameter).
This process is been triggered due to the respective setting of the
transfer method.
This transformation enhancement is automatically done during the
generation of the function module WL210 and ensures that the client of
the receiver system is added to the respective field during the build up
of the transfer list.
This automatic client transformation is not visible in the
<ZK>Transformations </>tab, however the system found that a user-defined
transformation is already present for the field &V1&.

How to fix this error?

Check if both client transformations (the user-defined as well as the
automatic client transformation) will lead to the same result. At the
latest this can be done after the transfer list has been built up. Check
if a different result is acceptable or would lead to errors and adapt
your user defined transformation accordingly.
