Approval rules Many organizations rely on an approval process to ensure that requests are reasonable and fit an organization's budget. The service catalog can use these classes of approvals:Table 1. Approvals Title Description Gating approvals Must occur before a request can be initiated. For example, allow a manager to reject an employee's request for a company car. Process approvals Take place within an execution plan process that has been initiated. For example, allow the security group to reject a request for access to SSN even though the employee's manager approved it. Note: To enable approval processes to operate smoothly, make sure that the appropriate users have the correct role, and that the role grants access to the necessary tables for users in all the relevant departments and domains. Set automatic approval rulesApproval rules can automatically set the approval state to something other than Not yet requested. As a result, an approval rule can create a set of approvers. You can also start the approval process by setting the approval state to Requested.Gating approvalsA gating approval acts as a gate through which a request must pass before it can start.Process approvalsOnce a request has passed its gating approvals, any relevant execution plans are initiated.Approve with a process guideProcess guides work similarly to approval rules in that their execution is controlled via a condition.Schematic of a hypothetical approval processIn the diagram below of a hypothetical approval process, the gating approval is color coded blue and an in-process approval is orange.
