Decision Types 
During an approval process, agents can decide on purchasing documents in different ways, depending on the following criteria:
Are the items of the document grouped into decision sets?
Is the decision taken per decision set or per item?
There are four decision types:
The document is approved by a single agent as a single, indivisible unit of decision.

Decision Type 1
The document is approved by a single agent. The decision is made individually for each item of the document.

Decision Type 2
The items of the document are grouped into decision sets. Each decision set is approved by a separate agent. The decision applies to the entire decision set.

Decision Type 3
The items of the document are grouped into decision sets. Each decision set is approved by a separate agent. The decision is made individually for each item of the decision set.

Decision Type 4
Decision type 4 is used, for example, for parallel approval with overlapping responsibility. In this case, however, an item of a shopping cart is part of several decision sets because it needs to be approved by several agents on one process level. For more information, see Agent Determination.
Note
Each process level is assigned one decision type. However, if the decision type chosen provides for an item-based decision (as in decision type 2 and 4), the user can still use the shortcut decision function in the Universal Worklist (UWL) and thus approve or reject all items at one time, just as in decision types 1 and 3.
When choosing decision type 3 or 4, the system creates several decision sets, depending on the areas of responsibility the items of the document belong to. For more information, see Decision Sets.
Note
For completion levels, only decision types 1 and 2 are available.
When choosing decision type 1 or 3, the responsible agent makes a decision for the entire document or decision set, whereas with decision type 2 or 4, each item can be decided upon individually.
