Add Save Event - Page Level
This event is invoked after the target records are successfully saved. This can be an Apex web service or JavaScript code snippet. Failure of this event does not rollback the saving of target records. If any updates are made to the target record(s) using an 'After Save event', the target record needs to be saved explicitly in the Apex / JavaScript code. Any failure of event needs to be addressed manually.
A standard SFM transaction which invokes After Save web service is 'Create Preventive Maintenance Plan From Account'. This web service calculates PM Plan Details, which include PM Coverage for all the Installed Products associated with the Account and next PM Schedule records.
