Buyoffs are an electronic way to approve the completion of a manufacturing activity performed on a shop floor.
They are an electronic substitute for the physical stamps applied to paper travelers by various people in manufacturing to record (or warrant) that they performed, checked, or acknowledged completion of a manufacturing activity.
To comply with regulations and produce high-quality products in a timely and cost-effective manner, manufacturers can use Buyoffs to play a significant role in achieving these goals by facilitating the elimination of paper documents in manufacturing while providing at least the same level of recording or warranting of the manufacturing activities performed.
In this blog post, we will see a short demo and also see in detail how the concept of buyoffs work in SAP Digital Manufacturing, including their benefits and how it looks like in Production Operator Dashboard (POD) during regular manufacturing operations.
Reduction in rework time through real-time task validation
By using buyoffs, manufacturers can validate manufacturing activities in real-time, reducing the need for rework later in the process. This leads to more efficient production processes and lower costs.
Reduction in manufacturing costs through real-time task validation rather than validation later in the process
By validating manufacturing activities in real-time, manufacturers can identify and resolve issues earlier in the production process, reducing the need for costly rework.
Conformance to federal guidelines mandated by regulatory agencies such as the FDA (Title 21 CFR Part 11) and FAA
Buyoffs can help manufacturers ensure compliance with federal guidelines by providing a digital record of completed manufacturing activities.
Create and Manage Buyoffs
Manage Buyoffs app is used to create buyoff requirements.
With Manage Buyoffs app, manufacturers can easily create and assign buyoff requirements to various Master Data objects, such as materials, routings, operation activities, work centers, and resources.
This app also allows manufacturers to assign these buyoff requirements to the relevant Supervisors who have the necessary authorization to approve them in the future.
By assigning buyoff requirements to specific Master Data objects and supervisors, manufacturers can ensure that the approval process is efficient and compliant with regulatory guidelines.
To create a Buyoff in Manage Buyoffs app, perform the following steps:
Click "+" to create a new Buyoff
In Main section, enter the Buyoff Name, Version, Description and set Status as "Enabled"
In Assignment section, click "Add" and assign master data objects to this buyoff
In Supervisor section, click "Add" and assign users who must have authorization to approve this buyoff
Click "Create" to save your entries
During normal manufacturing operations, workers can trigger buyoffs automatically in Production Operator Dashboards (PODs) by completing SFCs that match the master data assigned to a buyoff requirement.
In the example below, a buyoff will be triggered when an SFC of Material MZ_BR_F0001 and version ERP001 is completed at Resource BR-INSP002 and Work Center DCBR-I1.
When an SFC that matches a buyoff master data assignment condition is completed at a given Operation, message below will appear in the Production Operator Dashboard (POD) indicating that a buyoff is required:
The SFC will remain in a "Complete Pending" status until the buyoff is handled by a supervisor with the proper authorization assigned for that specific buyoff requirement.
Supervisors with necessary authorizations can then use Log Buyoff plugin to Approve or Reject the buyoff electronically, which will determine whether the SFC can proceed to the next Operation or remain blocked until the buyoff is approved.
This process ensures that all completed manufacturing activities are properly reviewed and approved before the SFC can proceed to the next operation.
Logging a Buyoff
Logging a buyoff simply means approving or rejecting it.
It is a crucial step in approving the completion of a manufacturing Operation on the shop floor. This process involves using the Log Buyoff plugin, which enables Supervisors to Approve or Reject buyoffs electronically.
To use the Log Buyoff plugin, Supervisors must first have permissions assigned to log each specific buyoff, which can be done in the Supervisor section of the Manage Buyoffs app, where Supervisors are assigned to each specific buyoff requirement.
Once Supervisors are authorized, they can use the Log Buyoff plugin to display and handle the buyoffs associated with a particular SFC, as you can see below:
This enables them to efficiently manage the approval process and ensure that manufacturing operations are completed in a timely and compliant manner.
Accepting or Rejecting buyoffs will determine whether the SFC can proceed to the next Operation or remain blocked until the buyoff is approved.
If the buyoff is Accepted, the SFC is moved to the next Operation. The following message is shown:
If the buyoff is Rejected, the SFC is not moved to the next Operation and remains blocked until the buyoff is accepted. The following message is shown:
When logging a buyoff, it is also possible to include Comments. If a buyoff is Rejected, a comment is mandatory, otherwise message below is shown:
If the buyoff is not yet Accepted or Rejected, the SFC remains in the "Complete Pending" status and it is not moved to the next Operation.
Before Supervisors can Log Buyoffs in Production Operator Dashboards (PODs), "Log Buyoff" plugin must be manually added to a custom POD.
To do so, create a brand new POD from scratch or copy an existing one, and add "Log Buyoff" plugin as you can see below:
