Number of characters users can enter on the Memo field onTransactions

Users can enter up to 999 characters on the Memo field on Transactions.

Note:
When users enter more than 999 characters on the Memo field via CSV Import, the import fails and users receive an error message: The field memo contained more than the maximum number (999) of characters allowed.

There is an enhancement request for increasing the number of characters for the memo field: Enhancement 94012 Need to increase the size of notes or memo fields like tasks/events/notes to be much larger, potentially unlimited.
