Define Scope within PDMS Data Source

Once an PDMS data source has been defined, the elements from within that source can be further restricted by defining a data source scope.

Only the elements within the chosen scope will be examined by the data source, and only those that meet the selection criteria of the data source (Element type(s), filters) will be returned in the report.

1. Click Scope on the AVEVA toolbar.

   The Scope window is displayed.

   

   The window is used to specify a list of elements. The report will be restricted to source data at and below the level of these elements in the element hierarchy.

2. If the current element is always to be within the scope, click the CE checkbox.

   Note: If/when the CE changes, so will the scope of the data source.

3. To add the current element to the source, click the Add CE button.

   The current element is then added to the Root Elements list.

4. To add further elements, make those elements the Current Element and click the button again.

   A list of root elements can be compiled in this way.

   

5. To remove an element from the list of Root Elements, select it in the list and click Remove.

6. If the scope of the data source is to be restricted to elements either partially within or completely within a specified volume, select either the Partially Within... or Completely Within... option from list of values in the Volume field.

   The Volume window is then displayed.

   

   

   The user can position the volume explicitly.

7. Click to display the Offset By fields which allows the user to enter offset values for the volume.

   

8. Click again to return to the explicit position text fields.

9. Click OK to position the volume or Cancel to discard any inputs and close the Volume window.

   The user is returned to the Scope window.

10. From the From drop-down list specify whether the scope is to be restricted to elements in the drawlist or in the obstruction list. Otherwise leave the drop-down set to the default selection of MDB, meaning that all elements in the database may be in the scope.

    

11. Click OK to save the scope settings and exit the window. Click Cancel to exit the window without saving.

    Note: When root element(s) added in scope are no longer available in current database then the DbRef will be displayed in scope with "=dbref[0]/dbref[1]" format.
