If a PLU item is made up of other PLU's, for example a cocktail or a 'Gin & Tonic', then you can create it as a package which will then show as individual sold items of stock. It will also suggest selling prices and achievable Gross Profit % if Stock Items are configured
Create the drink PLU however before clicking Save, tick the box that says Package and then click on Edit Package.
In the screen that pops up you can add the component PLU items. Using the drop down list in the top right of the screen select the drink Charge Code of the PLU you would like to add. You can also select the Brand and Category to filter the PLU Items that are displayed in the bottom section. You can also type what you are looking for in the Search box
Once you have located the PLU you wish to use double click it and it will appear in the top section. This PLU is then attached to the package. Repeat step 2 and 3 until you have added all of the component PLU Items and then click Save.
This takes you back to the PLU build screen, click on Save and the package is now created
