Cant post Work Notes

[Gerard9]

We built a number of new Service Requests, that create RITMs and SCTasks.  But for some reason we cant post 'Work Notes' on either the RITM or SCTask.  I have looked everywhere i can think of that might prevent being able to post.  

I can type into the field, but it wont post.  I would welcome any ideas or suggestions that might help resolve the issue.

Thanks

Thanks Saji,

yes to audit. and i tried all of the others and still no luck.

there are some other old REqs that are working fine.  I might just have to rebuild these REQs and see if starting again fixes the problem.
