This code checks if the VPGM__c field of the currentUser object is not null. If it is not null, it assigns the value of currentUser.VPGM__c to the fields Approver_3__c and VPGM__c of the CT object.

Details:

1. Condition Check: if(currentUser.VPGM__c != null)

   • This checks whether the VPGM__c field of the currentUser object contains a non-null value.

2. Assignment Statements:

   • CT.Approver_3__c = currentUser.VPGM__c: This assigns the value of currentUser.VPGM__c to the Approver_3__c field of the CT object.
   • CT.VPGM__c = currentUser.VPGM__c: This assigns the same value to the VPGM__c field of the CT object.

Purpose:

The code sets specific fields (Approver_3__c and VPGM__c) in the CT object based on the VPGM__c value of the currentUser object, provided it is not null. This could be used in a workflow where certain fields need to inherit a user's manager or approver information.
