Sum data from a column in parent but ignore duplicate data
Problem with data involving a Time Card Table and a Dispatch Table.
one Time Card : many Dispatches
Each tech has one Time Card per day and 2-3 Dispatches per day.
The Techs daily Time Card Record ID# is entered into each Dispatch when created. Here is what the columns in the Dispatch tbl look like (with about 10 columns of misc dispatch data missing for this example): Example Attached
This is one week of activity, and I want a summary report in the Dispatch tbl to show the total hours the techs were on the clock, to compare travel time, billable time, and clock time.
This example (164:29) is all I can get to show up on a Summary Rpt. I need to have only one TOTAL CLOCK for each Related Time Card. The actual time for tech GO was 31:28 and for tech JD was 48:30 for a total of 79:58.
