I need to add a custom module to store Collection Notes(Billing Notes) for our Accounts. The reason for the custom module is my Accounting Department wants their Notes stored separately so they can be searched or looked at on their own. The built in Notes feature does not have any categorization of notes.

For this Custom Module I need to store DATE OF NOTE, NOTE, ENTERED BY. These are the only fields I want . There needs to be linked to Accounts and I have added the LOOKUP field for accounts.

My question is I can't seem to get rid of 2 fields,  Collection Note Name and Collection Note Owner. Are those required for every custom module? How can I remove them?

I have attached a screen shot of custom module.

Any suggestions would be appreciated.
