This article will show you how to locate a standard for a Classification and the corresponding stack count if applicable.
1) Select option "Classifications"
2) Click in the Search box and type what you're looking for specifically. If you're not quite sure of the name you can type % followed by a portion of the name then end with a % sign. For my example I typed in %robe% then clicked search, which filtered all results and looked for anything with the word "robe" in it. (shown below)
In this example for this we can see the Target is set to 75 pieces per hour with a "stack Count/Bundle Size" of 5 pieces per bundle/stack.
