I have a requirement where I need to update/insert Cases/activity object records based on the actions happening on the 3 other objects ie Service Account, Repossession and Collateral Auction. These are all custom objects. I was planning to write the trigger only on 'Service Account' object and write whole logic even if something is happening on the field update of Repossession/Collateral auction object.
I thought I will put a process builder on these(Repossession/collateral Auction) objects when the field updates happen and then invoke the trigger in the update actions. Is this possible via process builder ? Or will I have to write separate triggers for each object fields update actions ??
