Purchase Order Approval Block

This module allows you to block the approval of an RFQ when an Approval
Block Reason has been provided. Upon confirmation of an RFQ the orders will be
waiting for approval by a Manager.

Configuration

• Go to ‘Purchases / Configuration / Purchase Approval Block Reasons’ and create
  the blocking reasons as needed, providing a name and a description. A field
  ‘Active’ allows you to deactivate the reason if you do not plan to use it
  any more.
• Assign the security group 'Release blocked RFQ' to users that should be able
  to release the block. Users in group 'Purchase / Managers' are by default
  assigned to this group.

Usage

Set the Purchase Approval Block

#. Go to ‘Purchases / Purchase / Requests for Quotation’
#. Create a new RFQ and indicate the approval block reason (found in the
right hand side of the screen, below the order date).

Search existing RFQ

There is a filter ‘Blocked’ to search for orders that are blocked for approval.
It is also possible to search RFQ’s with a specific block reason.

Confirm the RFQ

#. Press the button ‘Confirm’. If there’s an approval block, the order will
be set to status 'To Approve'. You will then need to request a Purchase
Manager to approve it.

Release the purchase approval block

While the RFQ is in draft, members of security group ‘Release blocked RFQ’,
can see a button ‘Release Approval Block’. From this point and on, anyone
seeing that RFQ will be able to validate it.

Notifications to followers

Followers of the RFQ receive notifications when an approval block has been
set or released.
