Here’s a question we ask a lot of logistics managers: how do you share shipment details with your carriers?

The answer is often the same. Emails. Phone calls. Some WhatsApp messages. A few Excel files going back and forth. Maybe an old EDI link with one or two big carriers.

It kind of works. Until it doesn’t.

A carrier misses an email and the truck never shows up. Someone types the wrong pickup date. A customer asks where their order is, and your team has to call three people to find out. At month end, freight invoices don’t match what was agreed, and sorting it out takes days.

SAP Business Network for Logistics, or BN4L, is built to fix this. It gives shippers and their logistics partners one shared place to work together. But getting it live and getting carriers to actually use it takes planning. That’s where a good SAP BN4L implementation partner makes a real difference.

Let’s break it all down in simple terms.

SAP Business Network for Logistics is a cloud-based network from SAP. It connects shippers with their carriers, freight forwarders, and logistics service providers on one platform.

You may have heard it called by its older name, SAP Logistics Business Network (LBN). It’s the same idea, now under the SAP Business Network family.

In plain words, BN4L is a shared space where:

  • You send freight orders to carriers
  • Carriers accept or reject them online
  • Carriers send status updates, like pickup and delivery
  • Both sides share documents, like proof of delivery
  • Freight invoices are sent and checked in one place

How Does It Connect to Your Systems?

BN4L works closely with SAP TM in SAP S/4HANA. Your planners create freight orders in SAP TM, and BN4L passes them to the carrier. When the carrier responds, the update comes straight back to SAP TM.

Carriers don’t need SAP themselves. They can join in different ways:

  • Through a simple web portal
  • Through EDI, if they already use it
  • Through APIs, for more tech-savvy partners

This is a big reason BN4L works well. Small and large carriers can all take part, each in a way that suits them.

BN4L has a few key areas. You don’t have to use all of them at once. Most companies start with one and add the others later.

1. Freight Collaboration

This is where most companies begin. It covers the daily back and forth between shipper and carrier.

  • Freight tendering: Send shipment offers to one or more carriers and get quick replies.
  • Order confirmation: Carriers confirm pickup dates, vehicles, and drivers.
  • Dock appointments: Carriers can book loading and unloading slots.
  • Event reporting: Carriers share updates like picked up, delayed, or delivered.
  • Document sharing: Proof of delivery and other papers are uploaded and stored with the shipment.
  • Freight settlement: Carriers send invoices through the network, and they’re checked against agreed costs.

2. Global Track and Trace

This part is all about visibility. It brings tracking events together from carriers, partners, and even devices, so you can see where shipments are and spot delays early.

  • Follow shipments from start to end
  • Get alerts when something goes off plan
  • Share tracking details with your customers

3. Material Traceability

This helps you track materials and batches as they move through your supply chain. It’s useful for industries where you need to prove where a product came from, such as food, pharma, or chemicals.

A good SAP BN4L implementation partner will help you decide which part to start with, based on where your biggest pain points are.

Let’s say you’re a manufacturer shipping goods to a customer in another city. Here’s how one shipment flows through BN4L.

  1. Your planner creates a freight order in SAP TM for the shipment.
  2. The order is sent to carriers through BN4L as a tender. It might go to one carrier or a few at once.
  3. The carrier sees it in their portal (or in their own system through EDI or API) and accepts it.
  4. SAP TM updates on its own. Your planner can see the carrier has confirmed. No phone call needed.
  5. The carrier books a dock slot for pickup at your site.
  6. The truck picks up the goods. The driver or carrier reports the pickup event.
  7. Tracking updates come in as the truck moves. If there’s a delay, you get an alert.
  8. The goods are delivered. The carrier uploads proof of delivery.
  9. The carrier sends the invoice through BN4L. It’s checked against the agreed freight cost in SAP TM.
  10. Any difference is flagged so your team can review it before payment.

From start to finish, everyone sees the same information. No chasing, no guessing, and far fewer mistakes.

It helps to see the difference side by side. Here’s what changes for each group.

For Shippers

Before BN4L:

  • Tenders sent by email, replies come in slowly or not at all
  • No clear view of where shipments are
  • Freight invoices checked by hand, line by line

After BN4L:

  • Tenders go out and come back through one platform
  • Live tracking and alerts for delays
  • Invoices matched against agreed costs, with differences flagged

For Carriers

Before BN4L:

  • Different formats and portals for every customer
  • Lots of calls asking for updates
  • Slow invoice approval and payment

After BN4L:

  • One simple way to receive and confirm orders
  • Updates shared once, seen by everyone
  • Faster, cleaner invoicing

For 3PLs and Freight Forwarders

Before BN4L:

  • Hard to pass orders down to subcontracted carriers
  • Visibility gaps between partners

After BN4L:

  • Orders can be passed along the chain on the same network
  • Everyone works from the same shipment data

In short, BN4L takes a lot of the friction out of working with logistics partners.

A BN4L project is a little different from a normal SAP project. It’s not just about your system. It’s about your partners too. Here’s the approach we follow at SCM Champs.

Step 1: Find the Pain Points

We talk to your transport planners, finance team, and a few of your carriers. We want to know where things break today.

  • Are tenders slow to get answered?
  • Is tracking the biggest headache?
  • Are invoice disputes taking too long?

Why it matters: The answers tell us which part of BN4L to start with.

Step 2: Pick a Starting Scope

We usually suggest starting with a pilot. For example, freight collaboration with five to ten key carriers on your busiest lanes.

Why it matters: A small, focused start shows results quickly and builds trust with carriers.

Step 3: Get Your SAP Side Ready

We check your SAP TM and S/4HANA setup and make the needed changes. Then we set up the connection between your SAP system and BN4L.

Why it matters: If SAP TM isn’t set up right, the network can’t do its job.

Step 4: Set Up BN4L Processes

We configure the network for your business: tender rules, event types, document types, invoicing flow, and user roles.

Step 5: Onboard the Pilot Carriers

We help your carriers join the network, whether through the portal, EDI, or API. We guide them, answer their questions, and make sure they’re comfortable.

Why it matters: A network is only useful if partners actually use it. (More on this in the next section.)

Step 6: Test With Real Carriers

We run full shipments from tender to invoice with your pilot carriers. Any gaps get fixed before go-live.

Step 7: Go Live and Roll Out

Once the pilot runs well, we go live. Then we bring more carriers and lanes on board, wave by wave.

Step 8: Support and Grow

After go-live, our team handles questions, fixes issues, and helps you add new parts like Global Track and Trace when you’re ready.

Here’s the truth. The technical setup of BN4L is usually not the hardest part. Getting carriers to join and use it every day is.

Some carriers are small and not very comfortable with new systems. Others already use many customer portals and don’t want another one. If onboarding is rushed, carriers go back to email, and the network sits there unused.

Tips for Smooth Carrier Onboarding

Here’s what we’ve found works best:

  • Start with your friendliest carriers. Pick partners who are open to change. Their success will convince the others.
  • Explain what’s in it for them. Faster tender replies, fewer calls, and quicker invoice approvals. Carriers care about getting paid on time.
  • Offer the right way to connect. Small carriers can use the web portal. Bigger ones may prefer EDI or API.
  • Keep it simple. Short guides, quick demo calls, and someone they can contact with questions.
  • Go in waves. Don’t try to onboard 200 carriers in one week. Bring them in batches.
  • Follow up after go-live. Check who’s using it and who’s slipping back to email, then help them.

At SCM Champs, carrier onboarding is a core part of our BN4L implementation services, not an afterthought.

You might wonder, “It’s a cloud network. Can’t we just switch it on?” Not quite. A lot sits behind a working BN4L setup:

  • SAP TM settings that must match how the network works
  • A connection between your SAP system and the cloud network
  • Process design for tenders, events, documents, and invoices
  • EDI or API links for larger carriers
  • Carrier training and onboarding support
  • Testing with outside partners, not just your own team

If any one of these is weak, the whole thing struggles. A good SAP Business Network for Logistics implementation partner brings people who have done this before. They know where projects usually get stuck and how to avoid it.

What to Look For in a BN4L Partner

Before you choose, check if the partner:

  • Has hands-on SAP TM experience, since BN4L depends on it
  • Has worked on BN4L or LBN projects before
  • Has a clear plan for carrier onboarding
  • Can handle EDI and API integration
  • Offers support after go-live
  • Speaks in plain language you can follow

SCM Champs is an SAP consulting company that works only on SAP Supply Chain and logistics. SAP Business Network for Logistics is one of our main focus areas, along with SAP TM, SAP EWM, SAP Yard Logistics, and warehouse automation.

Here’s why companies work with us on BN4L:

We know SAP TM inside out. BN4L and SAP TM go hand in hand. Our consultants understand both, so the link between them is set up properly from the start.

We take carrier onboarding seriously. We don’t just build the network and hope carriers show up. We help bring them on board, step by step.

We connect the full logistics flow. Since we also work on SAP EWM and SAP Yard Logistics, we can connect what happens on the network with what happens at your gate and inside your warehouse.

We start small and build up. A focused pilot first, then wider rollouts. This keeps risk low and results visible.

We stay after go-live. Our support team helps with day-to-day issues, new carriers, and adding new BN4L features over time.

We work the way you need. A full project team, a few experienced consultants to join your team, or ongoing support. You choose.

What is SAP Business Network for Logistics used for?

It’s used to connect shippers with carriers, freight forwarders, and logistics providers. Together, they can share freight orders, tenders, tracking updates, documents, and invoices on one platform.

Is BN4L the same as SAP Logistics Business Network?

Yes. SAP Logistics Business Network (LBN) is the older name. It’s now called SAP Business Network for Logistics.

Do carriers need SAP to use BN4L?

No. Carriers can join through a web portal, EDI, or APIs. They don’t need their own SAP system.

Does BN4L work with SAP TM?

Yes. BN4L works closely with SAP TM in SAP S/4HANA. Freight orders and updates move between the two automatically.

How long does a BN4L implementation take?

It depends on your scope and how many carriers you bring on board. A pilot with a small group of carriers can go live much faster than a full rollout to hundreds of partners. A short assessment helps set a realistic plan.

What is the hardest part of a BN4L project?

In most cases, it’s carrier onboarding. The technical setup matters, but getting partners to use the network every day takes planning and follow-up.

Why work with SCM Champs for SAP BN4L implementation services?

Because we focus only on SAP Supply Chain, we know both SAP TM and BN4L well, and we treat carrier onboarding as a key part of the project, not an extra.

Working with carriers shouldn’t feel like a daily fight with emails and phone calls. With SAP Business Network for Logistics, you and your partners share one view of every shipment, from tender to invoice.

But the network only works when it’s set up well and when carriers actually use it. That’s why the right BN4L implementation partner matters so much.

At SCM Champs, we bring SAP TM know-how, real BN4L experience, and a practical approach to carrier onboarding. If you’re planning a BN4L project, already using it but not getting much from it, or trying to get more carriers on your network, we’d love to help.

Get in touch with the SCM Champs team. Tell us how you work with your carriers today, and we’ll help you map out the next step.
