This topic provides the systematic instructions to perform the basic operations on the selected records.

Suppose here we consider that we want to persist custom fields on postnext call (which means first ‘self.next’ method of base would get called and then the control will come in postnext method written in extended component).

1. Write postnext method in .js file of the extended component – wherein you can call the custom Api for persisting the custom fields.
2. Expose this method in the .json file of the extended component.
3. Similarly we can add prenext method as well.(it would get executed before ‘self.next’ method of base executes).

   Note:

   The hooks for these methods to work should be a part of common infrastructure components in appshell.
4. Below is the list of CCAs and the common methods which has pre and post hooks:
