When you do a work order task, you must register the consumption of necessary items. A necessary item is a (spare) part that is required to do the work order task. The necessary items for a work order task are defined in D365 F&SCM in the work order line transactions.

When you consume or skip a necessary item, in D365 F&SCM, the related Work order line transactions are updated (consume) or deleted (skip). The work order line transaction is of type 'Required item'. Note: If you are working offline, the necessary item consumption registration is not synchronized with the Work order line transactions until you are back online.

Standard procedure

1.	On the Booking page, open the Parts tab.
2.	If you have consumed a necessary item, in the Necessary Items section, select the item and, on the section header, tap Consume.
	Note: If there is no need to consume a necessary item, tap Skip. On a mobile phone, tap the overflow menu [...] button of the necessary item, and tap the desired status. The Necessary Items section shows up to five items. If there are more, tap See more to see all items.

Notes

• You can consume or skip several selected necessary items at once. Select the desired necessary items and tap Consume or Skip. Note: On a mobile phone, on the Necessary Items section header, tap the overflow menu [...] button, and tap Select. In the list select the desired items. Again, on the Necessary Items section header, tap the overflow menu button and tap Consume or Skip.
• You can also register necessary item consumption on the Item Checklist page. To do so, double-tap (tablet or Windows device) or tap (mobile phone) a necessary item and tap Consumed or Skipped.
