You can compare combinations of data from a single table or combinations of data from different tables. The X and Y axis can therefore represent columns from the same table or from different tables.
When you compare columns from the same table, a fill operation from one cell to another cell moves data that exists in a single table. The data is available to move and the fill operation runs without the need for input.
When you compare columns from different tables, some records in intermediate tables might not exist in the database. These records might be required for the combination corresponding to the target cell.
When there is no data available to fill a cell, you must enter the data values manually. The job pauses when input is required. If the data coverage task is open, a dialog box appears with fields to enter data values.
Enter data values that match the column data type. A move operation fails if the data that you enter does not match the column data type.
