The SAP error message CNV_CMIS_G043 indicates that the system is a "Single code page system." This typically arises during data migration or conversion processes, particularly when using the SAP Conversion Management Information System (CMIS) or during the use of tools like SAP S/4HANA Migration Cockpit.
Cause: The error occurs because the system is configured to use a single code page, which limits the character set that can be used. This can lead to issues when trying to migrate or convert data that contains characters not supported by the single code page. For example, if the source system uses a multi-code page or Unicode, and the target system is a single code page, there may be incompatibilities.
Solution: To resolve this issue, consider the following steps: Check System Configuration: Verify the code page settings of both the source and target systems. Ensure that they are compatible. Convert to Unicode: If possible, consider converting the single code page
