Users with Purchasing User permissions can access the following functions within BMC Helix ITSM: Asset Management:

• Create and modify purchase requisitions that are assigned to the user's support group (this includes line items).
• Create and modify purchase orders.
  This permission grants access to only the purchasing functions (excludes receiving) and does not provide any access to areas where an 'Asset' or 'Contract' type permission is required.

Best practice: We recommend that you limit the use of these permissions to users who perform the following roles in the Asset Management Purchasing feature:

• Configuration Administrator—These users might submit purchase requests issued through the Change Management process.
• Purchasing Agent
