Linked filters are saved, enhanced filters that are integrated into a filter node. They are used when the content of a filter condition needs to be separated from the structure of the filter. For example, if a filter condition contains a path specification, it is easier to change the path later in a source, the linked filter, than to edit each filter node containing this path specification individually.
Filters are linked by
–creating filter conditions in an extended filter as a source and
–creating the filter node Linked Filter (category Utility) in another filter and selecting the source filter.
Example: Create a filter for the task “Rename purchased parts”
Purchased parts are to be renamed. For the Rename Model task, an enhanced filter is created that defines which parts are to be revised.
–In the filter tree, create the filter node Parameter Value on the preceding OR operation with the parameter CLASSIFICATION and the value =Purchased part.
–Place an “And” Filter Group (category Group) after the preceding Or operation, see setting Operations.
–Place the filter node Parameter Value on the AND operation with the MANUFACTURER parameter and the value =*. (The asterisk means: any value entered in the “Manufacturer” parameter applies.)
