If your page is PUBLIC, then value will be directly assigned to P1_SR_NUM item, otherwise, first APEX will show log-in page, after log-in, P1_SR_NUM value will be set to 495694-94583875
Check the incoming request for a passed parameter and set it to a value using something like this Request.querystring(“p_t10”). If nothing is passed the form is set up with a blank in the SR ID field, if a value was passed you populate the field, perhaps the log-in page can pick-up the parameter and store it in the session to later be put on the form after successful log-in.If you want to pass value via URL and capture the value in some apex item, then you can use similar URL that I have specified in above reply!
