Thank you for your response. It was very helpful. I can run the report from a Visual Basic (2013) project but I can't figure out how to change what the report displays base on a parameter.
The report has a list of PO Numbers on the right side when it runs. When the user clicks on one of them the report is reloaded to show the report for that PO. I want to be able enter a value in a textbox, so that when I click on a button the program sends the value to the report and it reloads the report for that PO Number.
How do you send a value to a report? How do you know what the parameter name is?
