As part of your Bluefield S/4HANA migration, you're going to need choose an approach to moving your code from ECC to S/4HANA.
Take a look at these 7 coding considerations for your S/4HANA migration to make sure you're using the best code migration strategy for your organisation.
1. Manual code remediation
Some of your ECC code won’t work with the new S/4HANA database. You’ll have to convert all the offending lines of code to work with S/4HANA. Your SI will probably want you to use their team of developers to do this.
2. Automated code remediation
Alternatively, you can look at tools that automate the process of remediating code to work with HANA. This saves money but crucially saves months of elapsed time.
3. Codebase selection
You’ll have to work out what you’re going to do with your existing custom code. Rather than ‘clean core’ think about which codebase you’ll use for your custom ABAP code (Stick with ABAP, move it to Steampunk, refactor in BTP, look at alternatives).
4. Integration architecture
If your SAP interfaces use PI/PO, you’ll need to look at alternatives. BTP, APIs, Azure Integration, other middleware?
5. GUI vs Fiori
Fiori is the replacement UI for SAP’s aging GUI. However, not every transaction has a Fiori alternative. Knowing which ones are which, and deciding if you want to change your UI for certain business people is an important consideration.
6. Transaction replacement
Some of your existing SAP transactions will be defunct. Do you know what they are and which functionality (transactions or Fiori) you’ll replace them with?
7. Z transaction replacement
You probably built your custom code decades ago. Since then, many layers of new functionality have been added to SAP (ECC and S/4) which you might not be aware of. Which custom “Z Transactions” can you replace with standard functionality you’ve already paid for?
With intelligent automation you can remediate more than 95% of the required fixes for HANA and S/4HANA automatically, and deliver secure, stable and optimized code within a couple of computing hours.
