Document management system: Why many companies operate more systems than they actually need

In practice, however, the picture is different: Many companies today operate complex DMS landscapes that were originally developed for requirements that have long since been adopted by other systems — especially from ERP platforms such as SAP. The result is often oversized systems, double data storage and unnecessary complexity.

The real question is therefore no longer: Do companies need a DMS? Instead: What tasks should a DMS even take on today?

Key Takeaways

• A DMS (document management system) is used to manage, store and organize digital documents.
• In many companies, DMS systems have grown historically and today perform tasks that have long been carried out by ERP systems such as SAP.
• This creates redundant systems, additional complexity and high operating costs.
• Modern IT architectures differentiate more between process systems (e.g. SAP) and archiving systems.
• Instead of oversized DMS platforms, many companies are increasingly relying on lean, SAP-integrated archiving solutions.

What a DMS was originally supposed to do

A document management system (DMS) was originally developed to digitize paper-based document processes.

Typical functions of a DMS are:

• Store and manage documents
• Versioning documents
• Access control and permissions
• Search and classification
• Approval or editing workflows

At a time when many specialist applications did not yet have integrated document management, a DMS was often the central platform for documents in companies. However, with increasing digitization, this role has changed.

The reality of many companies: established DMS landscapes

In many organizations, DMS systems have grown over the years. New requirements were added, interfaces were expanded and additional functions were integrated. This often results in an architecture in which the DMS tries to be at the same time:

• document storage
• Process platform
• workflow system
• archiving solution
• integration platform

The problem:

Many of these tasks are already being performed by other systems today. This creates double structures, especially in the SAP environment.

When the ERP system can already do more than the DMS

Modern ERP systems such as SAP S/4HANA today control a large part of a company's business-critical processes. This also includes the documents that are created in the context of these processes:

• invoices
• orders
• Delivery notes
• treaties
• personnel documents

These documents belong professionally to the respective business process — and thus to the system that controls this process.

If an external DMS also manages these documents, problems often arise:

• Documents are saved in duplicate
• Context information is lost
• Integrations are becoming more complex
• Migrations are becoming more complex

The DMS is thus becoming less of a solution — and more of an additional layer in the IT landscape.

Archiving is not the same as document management

One key point is often overlooked: document management and archiving are two different tasks.

A DMS focuses on:

• document editing
• versioning
• cooperation
• active use of information

An archive, on the other hand, has a different goal:

• long-term storage
• Integrity of information
• audit-proof storage
• Verifiability for compliance

Especially in the SAP environment, this separation is crucial. Many documents do not have to be actively processed — above all, they must be archived securely and in compliance with regulations.

A large DMS is often not the most efficient solution for this.

Why oversized DMS systems are becoming a problem

When companies try to cover all requirements with a single system, complex platforms with high operating costs are quickly created.

Typical challenges include:

1. High infrastructure costs: Large DMS systems require extensive server and storage environments.
2. Complex migrations: Especially in SAP transformations or cloud projects, DMS systems often become a brake factor.
3. Redundant data storage: Documents are stored both in the ERP context and in the DMS.
4. Maintenance costs: Interfaces, updates and operation generate permanent costs.

Many companies are therefore starting to reassess their document strategy.

The architectural trend: from a DMS to a specialized archiving solution

Instead of a large, central document system, many companies are increasingly relying on a clearer architecture:

• ERP systems control business processes
• Archives store information in a long-term and audit-proof manner

Especially in the SAP environment, this architecture is supported by standardized interfaces, such as:

• SAP ArchiveLink®
• SAP ILM
• CMIS

These make it possible to archive documents directly from SAP without creating additional system layers.

The advantage:

Documents remain available in the process context, while the archiving solution takes care of long-term storage.

Fewer systems, more clarity

The replacement of oversized DMS landscapes is therefore not a purely technical issue. It is part of a strategic architectural decision.

Companies benefit from:

• reduced system complexity
• clear separation of processes and archiving
• easier migrations
• lower operating costs
• better SAP integration

Especially in times of SAP S/4HANA transformations, this approach is becoming increasingly important.

Conclusion: Not every document needs a DMS

Document management systems have played an important role over many years. But with the development of ERP systems and modern archive architectures, their significance is changing. Many companies today find that they need less document management — and instead need efficient, SAP-integrated archiving. The real challenge is therefore not to introduce a new DMS. It's about questioning the existing architecture and deciding which systems are really necessary — and which complexity can be avoided.
