I am creating a custom Access Web App (2013) and I'd like to create a macro to update all filtered data in a datasheet.  I am displaying all work that can be invoiced.  The user can then filter this list by contractor name, job type, etc... using the built in filtering ability for each column.  They would need to click button to open a popup to enter an invoice number.  Can I write a macro to loop through *all filtered data* on a datasheet and update a column to a single value?
