Hi,

is it possible to edit and enable our customer coding after converting the SAP system to Unicode and not before (UCCCHECK)?

Hi Patrick,

yes, this is possible. But be aware: Once you converted the system to Unicode and did not adapt your coding it is no longer working.

You will run into short dumps depending on the amount of coding which is used.
So the recommended approach is to do the enabling before the conversion to Unicode.

Additional information about UCCHECK can also be found at the official WIKI: https://wiki.scn.sap.com/wiki/x/pgcCGg


Cheers,
Andreas

Patrick Gutheil , in support of Andreas' answer, I can attest that we went through this ourselves when we converted our systems to Unicode a few years ago. We thought we had caught all the custom programs and dealt with them before-hand, but inevitably a very small handful were missed somehow. They were old programs very rarely used, so it took a while, but eventually someone tried to run one and of course it dumped, just as Andreas describes. However, we knew what was going on, so it was easy to fix after the fact.

Nevertheless, best to catch as much as you can before-hand, as a Unicode-enabled program will work fine while your environment is still Non-Unicode, but a Non-Unicode program may have problems after the conversion. Sometimes the problem is as simple as checking the "Unicode-enabled" box in the program attributes, but other times an actual code change is required.

Cheers, and good luck!
Matt
