If you have setup either the warning limit or the maximum limit on the number of characters that can be entered then exceeding either of these limits will be indicated by the background colour of the subject changing.

 

An amber background means you have exceeded the warning limit.

 

A red background indicates you have exceeded the maximum recommended limited.

 

Note: ReportComplete does not physically limit you from typing too much, these are just visible indicators show that you have exceeded the recommended limits.
