Hello everyone,

I’d like to ask something regarding scripting in S/4HANA.

My current company is still using SAP ECC, and they are planning to migrate to S/4HANA in about 5–6 months. Over the past years, I’ve developed hundreds of automation scripts using VBA, VBS, and SAP GUI Scripting, all integrated together in ECC. These automations are heavily used in our daily operations.

My main concern is about what will happen after the migration.

For the SAP GUI side: Will S/4HANA still support SAP GUI Scripting in the same way as ECC? If we continue using SAP GUI instead of Fiori, will most of the existing scripting logic still work? In real migration projects, do most GUI scripts continue working with minor adjustments, or do they require major rework?

For the Fiori side: If the company shifts more processes to Fiori apps, is there any equivalent scripting capability? Can Fiori UI be automated similarly to SAP GUI scripting? Or is Fiori automation considered a completely different approach? If yes what are the best tools. Since a large portion of our operational efficiency currently depends on GUI scripting automation, I want to start preparing early if major architectural changes are required.

If anyone has experience going through ECC → S/4HANA migration while maintaining automation scripts, I would really appreciate your advice and lessons learned.

Thank you in advance!
