Configuring structures by occurrence effectivity
Modify the effectivity of an occurrence
Note
Any changes you make affect all occurrences sharing the same effectivity object.
Procedure
Select the line in the structure representing the occurrence whose effectivity you want to modify.
Choose Tools→Effectivity→Occurrence Effectivity→View, Create and Edit.Teamcenter opens the Occurrence Effectivity dialog box.
In the Occurrence Effectivity dialog box, choose Units or Dates effectivity, as appropriate, and define the effectivity range.
If defining unit effectivity, type the desired effectivity range in the Units box. Use the - character within a continuous range, and the , character to separate discontinuous ranges. For example, the unit range 1-5,7-9 defines effectivity for units 1 through 5, and 7 through 9 (but not effective for unit 6).
If defining date effectivity, select a cell in the From or To column, select a date from the calendar (and optionally type a time), and click Set Date to place that date in the selected cell. Click the Clear Date button to remove the date from the currently selected cell. Repeat this step for additional cells until you have entered all the desired date ranges.
Click the UP button to add the and up (open-ended effectivity) condition to the end of the unit or date effectivity range. If you are defining date effectivity,
Click the SO button to add the stock out condition to the end of the unit or date effectivity range. Note Teamcenter interprets UP and SO conditions as open-ended for revision configuration purposes. The revision is considered effective for any value greater than or equal to the unit or date value immediately preceding the UP or SO. Stock out indicates that existing stocks of a component revision should be used up before the next revision.
Check the Apply Access Manager effectivity protection check box to apply the predefined access rules to this effectivity.
(Optional) For date effectivity, use the End Item dialog box to define an end item to qualify the effectivity range. You must use this with unit effectivity to specify a product, module, or subsystem that carries the unit number to which this effectivity refers. You can select an end item in one of the following ways:
Clicking Open by Name adjacent to the End Item box and searching for an item by identifier and/or name.
Copying an item to the clipboard before opening the Occurrence Effectivity dialog box and clicking Paste adjacent to the End Item box.
Clicking MRU adjacent to the End Item box.
Note If you want to remove the entered end item, click Clear adjacent to the End Item box.
- Click OK to save the occurrence effectivity data you entered.
