The SAP error message CNV_PE_CHECK107 indicates that there is an issue with the parameter mapping in a conversion or migration process, specifically that a source parameter (SND parameter) does not exist in the specified interface. This error typically arises during data migration or conversion activities, often when using tools like SAP's Data Migration Cockpit or other conversion tools.
Cause: Missing Parameter: The specified parameter (&2) in the mapping (&1) is not defined in the interface you are working with. This could be due to a typo, a misconfiguration, or an oversight in the mapping setup. Incorrect Interface: The interface being referenced may not be the correct one for the data being processed, leading to a mismatch in expected parameters. Changes in Data Model: If there have been changes in the data model or the structure of the source or target systems, parameters may have been added, removed, or renamed.
Solution: Check Parameter Mapping: Review the parameter
