How to compare instances of 2 entities
For Example, i am having Entity "A" which is holding instances - 1,2,3 and Entity "B" which is holding instances - 1,2,3,4,5,6 . Now i need to check whether Instances of Entity "A" exist in Instances of Entity "B"and if it satisfies the condition i need to set Boolean Value to YES/NO.
Note : Here Entity "A" instances are entered by User in OPA Interview Screen(Dynamically) and Entity "B" Instances are Loaded from Service Cloud. I know there is function in OPA to check one Static value with many Instances of an Entity. is there any OPA Function to compare instances of 2 entities?
