Re: IP10 - Schedule Maint. Plan: Error Message - Entry missing in table T399W

There is a very old 4.6B OSS Note: https://service.sap.com/sap/support/notes/201784

This seems to indicate that some subscreens have a name that is too long.

Can you post a screen-shot of you T399W settings (via SE16).

Also, are you developing anything in the maintenance plans or task lists?
