## How to Perform a Change Operation on an Object referencing a Set

| ### What to do:
| In order to work through this example, you must have created the object ART-1450 Green Ink. For our example it is not important if this object has been created in an ad-hoc or non-ad-hoc process. Furthermore, you must have created a new work request. In our example the new work request is EWR-1510.
| Please note that in this example the change operation is to create a new version of an existing object.
| Select Start > Items. The Item mask is opened.
| Search for the item ART-1450.
| Change to the status 220 | Approved.
| Activate the corresponding work set EWR-1500.
| In the Work Set mask click the Complete button in order to release the work set. A mask is opened where a validity period has to be inserted in.
| In the Valid From field enter a validity date for the work set and click OK to confirm. The work set EWR-1500 is set to the state 270 | Complete.
| To update the Item mask click . The item ART-1450 is automatically set to the state 230 | Released.
| Change the status of the item ART-1450 to 240 | In Change.
| On the Item mask of ART-1450 select Revisioning > Create New Revision > Without Structure from the context menu. A new Item mask of ART-1450 is opened.
| In the Work Order field select the work order EWR-1510.
| The work request / work order EWR-1510 is needed as a reference work order / work set for the final process of creating an item. The work order EWR-1500 cannot be used again since it was used up for the completion of the work set EWR-1500.
| To save the entry click .
| A new version of the item ART-1450 has been created.
| The predecessor version of the item ART-1450 will become invalid when the work set EWR-1510 is completed and the new item version has become effective. The validity is indicated in the Effectivity field of the item mask.
| Please note that a new object version can only be created if the referenced work set is in state 110 | In Work.
| Instead of creating a new work request EWR-1510, it is also possible to add an additional set to the work order EWR-1500 and reference this work set.
