Hi @ayushhtiwari , Let say when you write script _operation="delete" for First Name by extending nms:recipient schema and update the database structure, firstName attribute along with its data will get deleted from database. 

@god_prophet , looks like this is custom attribute which you have removed from nms:recipient schema. Search the same in recipient's input form

@god_prophet , Might be those are calculated fields. So no separate field will get created in database. But these calculated fields might be used in Input form. So you're getting the error. One possible solution is, add those attributes again in your recipient schema, and first remove it from nms:re...

@god_prophet , You have to add your new field in nms:recipient input form (/Administration/Configuration/Input forms/ ) Input form

Hi @Sujith_02kumar , Goto /Administration/Configuration/Data schemas/ and search for cus:Test schema. In element tag, add autopk="true" and update the database structure. <element autopk="true" label="test" name="Test"/> Disconnect and reconnect the console and now check your input form.

@Sanjana12 , All kind of Delivery activities in 'Action' tab will utilize the delivery template, and if you modify it by clicking 'Edit link', basically you are editing the parent delivery template itself. And this will impact other campaigns which use the same template.  

Hi @Sanjana12 , For continuous delivery it will get changed.

Hi @Kamaleshvaran , In general mirror page link will be valid only for 60 days. If you're trying to render the mirror link of 60 days older delivery, then you can't able to view the mirror page.
