OVERVIEW

What This Means for You

A system conversion transforms your existing ECC system into S/4HANA. It keeps your configuration, custom code and transactional history, which is attractive for companies whose processes still serve them well.

Conversion is technically demanding. Prerequisites must be met, such as Business Partner conversion through Customer-Vendor Integration and finance data consistency, custom code must be adapted to simplification items, and the conversion itself is run with the Software Update Manager and, where needed, the Database Migration Option.

Webtel prepares and rehearses each step, measures downtime in mock conversions and plans the final cut-over around your business.

Every Webtel engagement has a named lead, a written scope and regular progress reporting. We work alongside your IT and business teams, explain choices in plain language and leave you with documentation and knowledge, not dependence on us.

AT A GLANCE

What Makes SAP S/4HANA Different

SAP S/4HANA is SAP's current-generation ERP for mid-sized and large enterprises. It runs on the SAP HANA in-memory database, with a simplified data model and a modern user experience.

One data model

Finance and logistics share one source of truth, including the Universal Journal.

Real-time

Reports and planning run on live data instead of overnight batches.

SAP Fiori

Role-based apps that work on desktop, tablet and phone.

Embedded analytics

Insight inside the transactions people already use.

FAQS

Common Questions

What is the difference between conversion and a new implementation?+

Conversion keeps your existing system, configuration and history; a new implementation starts fresh and migrates selected data.

Do we need to move to the HANA database first?+

No. SUM with DMO can migrate the database and convert the system in one step.

Can we improve processes during conversion?+

Some improvements can be made, but most companies plan a follow-up phase for larger changes.

Do you work with companies across the Gulf?+

Yes. We work with S/4HANA customers across the region and beyond, combining remote delivery with on-site work where it helps.

Can you work with our existing SAP partner?+

Yes. We can take on part of a programme, provide specialist skills or take over from another partner after a structured handover.

How do you price this service?+

We provide a written proposal after a short assessment, as a fixed price for a defined scope or as time and materials.
