There are 2 types of non-unicode in the SAP system, either MDMP or single code page. You can determine the type by the following method,
Report RSCPINST
Using the transaction code SE38, run the report RSCPINST. From the initial screen, click on Current NLS config.
Look up on the Configuration type, the output will list you either it is in Single Code Page or MDMP.
Table TCPDB
Open transaction code SE16 / SE16N and enter the table name TCPDB. If you see only 1 line from the table list – it means that your SAP system is configured under Single Code Page. Else, if more than 1 lines, it is under MDMP.
