FileMaker Magazine Posted October 13, 2020 Share Posted October 13, 2020 Here's an interesting dilemma. How do you track when specific fields are modified and adjust your JSON object so it only includes the data which was modified? Or, how about knowing when a user has modified specific fields, then having the user interface direct them down a different path than if they had modified others? In both situations, you simply need to know when a field was modified. Using the Get ( RecordModificationCount ) function we can know THAT a given record was modified and using a modification field we can know WHEN it last happened. What we don't know is when only a specific set of fields is modified. We also may need to know exactly which fields were modified in order to take some type of action. This is where Detecting Data Changes is quite helpful. There are a number of ways this can be accomplished and the solution, as always, depends on what your needs are. In this video, I showcase a method I use to detect data changes and then generate a JSON object based on specific fields which were changed. If you find your solution needing to work with an external API or needing to simply know when certain fields have been changed then you're sure to find some valuable info within this video and technique file.
