7 steps to a SAP PI to PO migration

Some time ago I created a webinar about SAP PI to PO migrations. I wanted to use the content and share it because it is quite useful for everybody working on a migration. I can see that it is some of the questions that I got on my latest webinar was also about the process. I do hope that this gives a better understanding of what is happening.

As with all things, there are 7 steps to make a good SAP Migration. So if you are in the process this is the steps that I would recommend that you take. It is assumed that you will migrate to a new system because it will make it easier to migrate a single interface at the time. If things does not work you will always have a backup plan.

The 7 steps are the following:

  1. Goals
  2. Current integrations
  3. Pattern mappings
  4. Resource consumption
  5. Migration phases
  6. Development
  7. Testing

The process should be very iterative because you learn a lot in the process that you can use to migrate other interfaces. I the current integration you are going to map out all your existing interfaces together with what types of pattern they are using. This information will then be used in the migration phase and how it is going you may get input on how the next interfaces can be migrated.

You can view this in two different ways. Either you can watch my Screen recording video of it.

Or view the slides here and download them if you want to be using them.

I have also created a longer article about some of the SAPs you need to consider more in details in the blog SAP XI/PI to PO migration.  It is not the same and the two have a lot in common.

Testing async/sync sync/async bridges in SAP PI

I this week we have added a new functionality for testing your SAP PI/PO interfaces.

IRT is a custom build application that works with SAP PI/PO to make sure you can record messages from your production system and run them on your development system. All with a few clicks in the application.

Watch the video to see more about the application

We got a client request to support async-sync bridges without BPM, and then we added support also for sync-async bridges. The system will then figure out what type of pattern that you are using. Based on the pattern modules and recording will then happen with data.

The other feature is to make sure you can limit the number of test cases you have. For instance, you may have different order types on your orders. And they each follow a different rule set and is mapped differently. If you have recorded 100 messages in total but only 5 for one type and 95 for the other type. You may just want to test with five messages for each, so verify that your interface. Then you can use the new trim functionality to delete all the other 90 test cases, so you just have 5 for each type.

SAPPHIRENOW 2017 from an integration perspective

SAPPHIRENOW and the ASUG annual conference is just around the corner. I’m looking forward to packing my bags and get on the way to the event. To see what is going on in the SAP ecosystem.

I normally do a short preview of the session that I’m planning to attend at the conference so you also can follow along in what is happening. So this blog is about that.

As something new I’ll try to create Facebook live videos from the conference if it possible. I guess there is a lot of things that can go wrong like wifi and location. I’ll give it a try so you can follow along.

I recorded a video on the agenda that I have put together and my thought about it. You can view it here on facebook please comment if there is a session that you think I should add to my agenda.

If you want to meet, I’m planning to see the keynotes at the remote theater DS425. I do hope it is a place where they will stream the keynotes otherwise I may go to find a different location

Here is my list of integration topics. If you are looking at IoT/SAP Leonardo and API there is also many sessions on those. I do hope to be able to attend some of them.

SAP Integration Landscape and Emerging Complexity

The field of process integration is changing quickly, setting new challenges for Integration professionals, and I think a good understanding of the available tools is key.

When we talk about paradigms in process integration, there have been 3 major phases:

  • Mainframes: Back in the day, most companies had one mainframe or two. The good thing about the mainframe was that it was fairly simple to integrate what were essentially internal programs – even if you had to work across mainframe platforms.
  • Client-server: With the emergence of client-servers and SAP R/3, the number of application servers was growing quickly. Suddenly, as an Integration Department, you had to figure out how to integrate the applications in your landscape so that you could create a new interface. In SAP terms, it may have been a Business Connector or eXchange Infrastructure (XI). You only had one tool to use.
  • The Cloud: Today, cloud integration is the norm, and the goal is to be able to quickly and easily leverage new cloud capabilities from existing development. A couple of examples of existing cloud capabilities are Hybris Cloud for Customer (e-commerce solutions) and SuccessFactor (human capital management).  There are also a number of non-SAP cloud applications. In fact, you most likely have some of them in your landscape already. As the integration expert, your job requires you to make them all play together seamlessly. Some come with prebuild content others you have to create for yourself.

As I said earlier, it used to be that you had integration consolidation that mostly worked in XI/PI. Now, Integration departments are faced with a very different landscape, driven by the need for new integration capabilities, and need to be looking outside of their space at the tools that are already available in other areas of process development. If we understand what’s out there, we can choose the right tool for the job.

I’m talking about tools like the HANA Cloud Platform – integration services (HCP-IS)/HCI, Process Orchestration (PRO), API Management, and Data Services to do bigger data ETL. We’ve also got the Application Integration Framework Overview (AIF), for when you want to do any integration with backend services. There are also SAP Gateway solutions available for exposing OData. Those are the SAP integration technologies that I can think of off the top of my head, other vendors have similar offerings that may be relevant.

I did this exercise with a customer and we spend 6 hours on the different topics and when it did fit into their architecture.

The big problem for the integration manager/architect is that you need to know the tools, and know when it makes sense to use one and how to select one over another. You also need to be able to train your team to use them. As you learn more, you’ll find a lot of overlap between the capabilities of the various tools, and knowing what each one can do will allow you to streamline your process when you have complex situations.

The challenge with all these tools is that it is both labor-intensive and potentially expensive to try them out. Say you have a situation where you want to expose some data to the user. First, you will have to figure out the logic and the capabilities of the various tools to find the best one to combine the elements so your API management will call  PRO or Gateway — to get or expose some data. Then you’ll need to acquire the tools and start using them, in order to really understand where they fit and what you can do with them. Once you get that down, you will need to work out how to leverage the technology internally. So, a lot of work is involved whenever you introduce new technology like this. You also have to keep in mind that you will be paying for licensing to use the tool, even if you don’t end up implementing it.

So as integration experts and enterprise architects, working in a rapidly changing field, we want to do our homework and really understand any tool and how we can leverage it before we place it in our systems.

What is your strategy for landscape integration? How do you cope with training problems?

How the Seeburger Migration Tool Works

 

I can understand that there is a bit of confusion about how our Seeburger Migration Tool works for converting from Seebuger BIC to the B2B Add-on.

I hope this post will make things clearer.

The big problem is that Seeburger’s XML representation of the EDIFACT/XML formats is different from the ones that form the SAP B2B Add-on. The root node is different, and there is a difference in how Groups and some fields names are made. It is therefore a bit of a challenge to move from one format to the other. Below you can see what the SOT tool does.

I have tried to illustrate the process in the following diagram:
How SOT functions

SOT is a small, self-contained web application that runs locally on your own PC. Once installed, you are able to configure which PI system it should use.

The process is the following:

  1. The user selects a Message Mapping from a drop-down list and which External Definition to use for the mapping.
  2. User Presses Fetch and Update.
    1. This will download the Metadata from the mapping.
    2. Find the Seeburger XSD contained in the mapping.
    3. Compare the existing Seeburger format with the B2B Add-on format. It will then know that it needs to convert from /LIST/S_UNB/S_UNH/G_SSG25/S_LIN/D_1082 to /INVOIC96A/M_INVOIC/G_SG25/S_LIN/D_1082. It is using an algorithm for the comparison, so nothing special is required for the different message types and versions.
    4. Go through the mapping metadata and convert all occurrences of the first Xpath to the second.
    5. Alert if there is a difference in the structure that is not accounted for, or if there are other errors.
  3. The user can then select Update. This will upload the new message data to the server, and the mapping will use the new definition.
  4. You will have to open the mapping and save it to make sure it compiles the mapping files.

You will still be able to use the same original mapping; it will just work on the B2B format.

The functions that you use will still be in the mapping, since we are only changing the use of XSD.

If you want to see more, I suggest that you check out the tool page for SOT.
