Removing an item from a data series

You can remove an item from a data series by selecting a data series, study event, or form. To keep the item in the data series but remove the data mapping for a study, unmap the item.

In the Project Explorer, select a data series.
The Data Series Editor appears in the workspace.
Right-click the item with an association to remove, and select Remove.
A confirmation message appears.
Click Yes.

In the Project Explorer, select the form or study event containing the item to remove.
The editor for the study object appears in the workspace.
Select the Data Series Summary tab.
If a form is selected, its items appear in the grid.

If a study event is selected, its forms appear in the grid.
Optionally, to change your view of the grid, use the filters at the top of the grid.
In the grid, follow the row containing the item across until you reach the column of the data series from which you want to remove the item, and point to the cell.
A drop-down arrow appears at the end of the cell.
Click the drop-down arrow, and select None.

The Data Series Summary tab appears in the editors for study events and forms.
