Changing Connections between Filters

If you add several filters to a filter chain, you may end up with unwanted connections between filters. These connections may change the logic of the filtering operation and prevent you from finding the data you are looking for.

To remove a connection between filters:

  1. Move the pointer over a connection you want to remove.

    The pointer changes to a pair of scissors and pipe turns red. If the pointer does not change and the pipe does not turn red, then the connection cannot be changed.

  2. To remove the connection, click the mouse button.

In this example, we have added a filter to pass courses which have a service date of August 17-19, 1998. What we are trying to find is all courses taught on a consulting basis or are taught in Rockville on August 17-19, 1998. However, as created, the filter actually finds all courses who are either taught as consulting or are taught in Rockville and which have a service date of August 17-19, 199.

By removing the pipe leaving the output of the SERVICE filter, we prevent that data from passing through the SERVDATE filter and achieve the results we want.
