Set and get parameter id
I need to store one variable value and I need to retrieve the same variable value in same program. For this I have written set and get parameter ids in the same program. It is working fine but if I log off the system and if I logon the system it is not working I mean before log off the variable is showing some value if I log on again that variable is showing empty. But I want to capture the field values after log off and log on also. Is there any other option can I use table?
Please help me I will give points.
