Message text: Simulation preparation function (WL2SIMPR) module not required
For simulation type 2, the transfer list remains identical and does not
need to be enhanced with simulation-specific information. Therefore also
no simulation preparation (WL2SIMPR) function module needs to be
generated.
The task of the WL2SIMPR function module is to enhance the transfer list
with simulation-specific information prior to calling the simulation
function module (WL2TRFMSIM).

The SAP error message CNV_PE364 indicates that the simulation preparation function (WL2SIMPR) module is not required in the context of a specific data migration or conversion process. This message typically arises during the execution of a data migration project, particularly when using SAP's Conversion Tools or the SAP S/4HANA Migration Cockpit.
Cause: Module Not Required: The error suggests that the specific simulation preparation function is not necessary for the current migration scenario. This could be due to the configuration of the migration project or the specific data being processed. Incorrect Configuration: The migration project may not be set up correctly, leading to the system attempting to call a function that is not applicable. Version Compatibility: There may be compatibility issues with the version of the SAP system or the migration tools being used.
Solution: Check Migration Project Configuration: Review the configuration settings of your migration project to ensure that all necessary parameters are set correctly. Make
