How to use the ‘Pegged Supply’ UI in Supply Planning

Dear community members,

in this blog post I would like to provide some insights into how best to use the ‘Pegged Supply’ UI in SAP Business ByDesign, leveraging some recent improvements that have been done in this area.

Imagine you have a production schedule and you want to understand, if there are any issues with late components and what would be a potential impact on the demand situation.

To start with the analysis, you could use the ‘Supply Control’ work center, where we offer two views:

  • Process Production Proposals
  • Monitor Production Requests

In my example, I will use the ‘Process Production Proposals’ view, but a similar approach could also be used starting from the ‘Monitor Production Requests’ view.

First you need to select a list of documents you are interested in:

Next you can open the ‘Pegged Supply’ UI by ‘Navigate to – Pegged Supply:

Since this action is mass enabled, the UI is opened for all selected production proposals:

The upper table shows the selected proposals, and in addition the ‘Component Delay’ column highlights, if there is any supply element delayed to cover the dependent component demand of the production proposal. It shows the maximum delay of the input components.

In the second table ‘Details: Pegged Supply’ all supply elements are listed that are used to cover the any component demand. In my example, a purchase proposal is late by 4 days for component ‘SR_CP2’.

With release 2205 a third table ‘Details’ Top Level Pegged Demand’ was added, which you might already know from the ‘Top Level Pegged Demand UI’. Having the information of the pegged supply and pegged demand available in one UI however should provide you with a much easier way to analyze the situation. In my example, a sales order is also impacted by the late component.

Of course there are now multiple solution strategies to come to a feasible plan, e.g.:

  1. Ask supplier for faster delivery
  2. Check if component SR_CP2 is used by other production proposals that are less important. You can use the ‘Open Product Planning Details’ action to easily access the supply and demand situation for that component.
  3. Reschedule the production proposal to better understand the impact on the sales order.

I will focus on the third strategy. The easiest way is to directly navigate to the material flow UI for the late purchase proposal:

From here I can directly perform the action ‘Reschedule Bottom-Up’ which will push out all not firm proposals that are pegged to the reference document of the material flow, which is the purchase proposal, that is late. The ‘Reschedule Bottom-Up heuristics can only be executed for the reference document of the material flow UI. That is the reason, why the material flow has to be launched from the late purchase proposal, and not from the production proposal.

After execution of the bottom-up heuristics, the planning situation looks like this:

You might wonder why there is an overlap of the purchase proposal and the production proposal of two days. The reason for this is, that the component demand for component SR_CP2 is two days later that the start of the production proposal.

You now have immediate transparency of the impact of the component delay on the sales order with only a few clicks.
