What is a good technique for locking certain fields in a layout. For example I have service tickets with certain fields that need to remain locked and certain fields techs need to edit. I have been locking fields based on another "lock" field or at validation and that works fine for users that are updating via filemaker network or on a pc. But there are times when its done from a mobile phone browser and what happens is a user will write up a a paragraph and for whatever accidental reason update a locked field such as a serial number or job number and they go to submit and are forced to start over again since it will not allow the update and there is not revert option.

btw this is being done in FMP 11

thanks

Have you tried using a different layout for mobile users?

A different layout wont solve this one.

Consider using GLOBAL fields to allow the data entry via IWP and then script the data being committed rather than try and rely upon FMs inbuilt modification checking. If you take control via a script then you have every option at your disposal.
