Viewing or Changing Supporting Detail

In forms, cells with supporting detail have a light green background.

To view or change calculations or supporting data:

Open a form, and then select the cells for which to view or add detail.

You can select one cell or contiguous cells in a row or column. The section cannot include a combination of rows and columns. Select cells that are in the local currency so that you can write to them.
Select Edit, and then Supporting Detail.
View or change the line items or calculations that aggregate the data in the selected cells.
