You pass a CDT that has some value in it.
how i passed cdt
Paste the code. Screenshot of the values that are there in your variables.
One of the two parameters you have passed in cdt difference function contains null data, You should add a null check for both the cdt variables first and then use the function like shown in the below example.
.
why we use {}
why not used null or blank.
I dont know diffrence between {}, null and blank....
