The appearance of the fast tab 'Lasernet - License plate label setup' is based upon the 'Work creation process' and 'Work order type'. For this fast tab to appear/disappear, the following article will discuss the needed criteria.

Mode fields

The Mode field on the Mobile device menu items form can either be set to 'Indirect' or 'Work'.

Mode = Indirect

• When Mode is set to Indirect the Activity code field decides if the fast tab should appear or not.

• If the Activity code is set to Reprint label, only then the fast tab appears.

• For the selection of all other values within the Activity code field, the fast tab will not appear.

Examples:

 When the Activity code is set to 'Reprint label':

Mode = Work

In this case, the Lasernet fast tab will only appear for all the Work Creation Processes that come under the following Work Order Types:

• Purchase Order

• Transfer Order

• Production

For Work Creation Processes that come under all other Work Order types, the fast tab will not appear. These Work Order Types include:

• Return Order

• Inventory

• Cycle count
