In reporting function i can define input parameters and its validation. In my case there is a simple report what is require a username as an input parameter and after that generate a word document which is contains the properties of this user.
But if i do for example typo or i add not existing username it will generate an empty word document. So here is my question:
Is there any way in parameter validation part to check the input parameter in database to inform users like “Username not extist” before the report execution?
