Hi,

You have not yet instantiated the references you have declared before assignign values to them.

I would suggest you to use the following 2 statements to instantiate them:

CREATE OBJECT lo_act_rec.

CREATE OBJECT lo_act.

Or if you have any specific constructor methods within the corresponding classes, use them first before assigning values like this.

Very often you might have methods to create objects from a particular structure, etc... Please check for this in the class you are using.

Hope this helps.
