After update NEX rules test conditions against records that have been changed, and apply to the post-merge state of the incoming data.
These rules can be used to inactivate records matching the specified criteria.

		Transformation involves modelling incoming files so that they map to the Network data model.
NEX rules are applied after transformation to clean up strings or apply required business rules.

		After Update
		Feed acceptance rules are triggered at each stage of data load based on record counts. They can be used to fail a job, for example, that contains too few records.
		6
		Match and merge compares incoming and local records to identify matches and merge matching records.
NEX rules are not applied at this stage; match rules configured in Network govern match behavior.
		Rule expressions enable you to enforce data quality standards for incoming data, throughout the data load process.
		File preparation includes the transfer and preparation of files intended for data load.
Specified NEX rules are applied after file review, before files are joined.
Rules might be used, for example, to format custom keys consistently.
