This event is invoked on clicking Save/ Quick Save in SFM Delivery. This can be an Apex web service or JavaScript code snippet. This event is invoked before the target record is saved. This can be used for doing any special validations which cannot be defined using SFM Data Validation Rules. This can also be used for updating some field values based on the values of other fields.

If the 'Before Save event fails', the Save operation fails.

The standard SFM transaction 'Create Child Installed Product' invokes a Before Save/Insert web service to validate the Product field value, and to update Installed Product Id with the Serial/Lot Number field value entered by the user.
