Main, Credit, Misc, and Misc 2 are the four pages of the Customer Code Update Report (RCCU), which include the various fields from Customer Maintenance (MCR) that you can update with RCCU. Locate the field(s) you want to update, and in that field, fill in the new value that you want the field to have after you run RCCU. Some fields have an arrow that you can click to display a list from which to select the new value. If you want the new value of a field to be blank, enter a # (pound sign) in the field.
