Using creation profiles, you can define the criteria for the creation of SA releases (for example, you can influence the quantities and dates transmitted). SAP recommends defining the Creation profile field as a mandatory-entry field (in Customizing for Purchasing: Scheduling Agreement ® Define Screen Layout at Document Level).
