Hi

From what I can see in the doc you attached in your earlier post, you are looking into a macro which opens a form - SET DATE PARAMETERS.

I don't use this method so I'm guessing a little, but I suspect that the "z_log_refresh" query simply provides data to the form when it opens. What you need to show us is the form (SET DATE PARAMETERS). I suspect that there will be one or more buttons on that form with OnClick events attached to them which perform the data updates. I suspect your answers will be in the VBA behind that form.

On second thoughts, if the original developer is using macros, then there will be macros behind those buttons.

Regardless, I think the next link in the chain you need to examine is the form.

Cheers

PS I think that query is simply recording who is opening the form (and perhaps doing an update) and at what time. Something along thjose lines anyway.
