FAQ (Frequently Asked Questions)

Can we update parent record from child record in Salesforce?

You can use process builder to update parent record from child. Create a process builder on child object and update parent object, here I am using account and contact. Created process builder on contact and updating account status field when contact status is rejected. Please find below screenshots for reference.

Can we update child to parent in Workflow?

You cannot update a child record's field from a parent object using a Workflow rule. Workflow rules are designed to operate on the record on which the rule is triggered and cannot directly update fields on related records.

Flow to Update Parent Record based on multiple Child Records

While looping through the lines, use an Assignment Element to add the current Quote Items Product Category to a text variable. For example, let's say the text variable is called varProductCategories.
