Scrolling in Pipeline View
By default, you scroll vertically or horizontally through the entire Pipeline view. However, you can enable horizontal and vertical scrolling for each column in Pipeline view. Independent scrolling is especially useful when mapping a large amount of data in the Pipeline view.
To enable independent scrolling in Pipeline view
Right-click anywhere inside the Pipeline view and select Enable independent scrolling to scroll through each column in Pipeline view horizontally and vertically independent of other columns. Tip:
While scrolling through a large amount of data, if you do not want Designer to display the links if the source or target variables are not visible, right-click anywhere inside the Pipeline view and select Hide links if variables are not visible.
