I have to capture data from sites and i assign a 3 digit code that i created in the data model.
I created a report template that i need to be able to set a parameter so that when i ask to run the report it needs to ask me the specific 3 digit code so that only 1 data entry gets displayed.
Does any one know if this is possible.
yes, this is possible. you can find guidance in the Advanced Reporting Handbook under custom parameters:
We got this working through that handbook instructions and just keeping in mind filters also need to make sure are applied to get the parameter to functionally apply.
