Row stated twice

Two rows of one table state the same thing, such as two rows for one location, or two demand rows for one product at one location. A row for ALL counts as a row for every product at its location. Nothing says which row applies, so Create Scenario does not save the scenario, and Network Optimization and Cost to Serve stop on such a scenario.

What to do

The message names the table, the rows and what they repeat. Keep one row for each, or, if the rows are parts of one total, add them up with an Aggregate node before the Map node.
