Steven Connolly In classic, I have a visualforce page that launches in a new window. In Lightning, the page launches within the main window and replaces the screen. How can I change the behavior in Lightning to launch a separate window?
I have a custom button that works in classic where we launch a separate window. The Behavior is set to Display In New Window. However, in my Lightning Experience test, this page replaces the main content. How can I alter the Lightning experience so that it also pops open a new window instead of refreshing the main screen with the page?
Few things you can do
1. Skip validation rule for a certain profile in case a user need to add product he need to ask user in that profile, only for old opportunties.
2. Create a boolean field on Opportuntiy and mark it true for old opportuntiy and skip validation if this flag is true.
3. Create a one time batch process to add product to Opportunity by deactivating the validation rule for the instance when batch runs
4. Search for a criteria which are old opportunity , Put the criteria in custom setting and add the criteria in Validation rule , say it Old opportunities are those created above January'16 , so store this date in custom setting and add condition in Validation rule that skip rule if createdDate < Jan'16
