How Secure Is Your Business Data? Elevating Access Control with SAP Business One
Product costs, selling prices, profit margins, customer data, and financial information are all critical data that affect a business's competitiveness. But when this data is scattered across multiple Excel files, an organization may be exposed to risks it cannot see.
The key question isn't just “is the data correct?” but “who can access the data, who has permission to edit it, and how well can the organization trace changes after the fact?”
Excel remains a useful tool for analysis and reporting. However, when critical data is copied, forwarded by email or chat applications, and edited separately across multiple versions, keeping that data under systematic control can become more difficult.
SAP Business One, an ERP system for growing businesses, helps organizations manage data and assign user permissions through a central system, while supporting approval processes and change tracking, depending on the system's capabilities and appropriate configuration.
Limitations of Managing Data with Excel That Organizations Should Consider
The problem doesn't lie with Excel itself, since Excel and the related file-storage platforms already offer data protection capabilities. But risks may increase when an organization lacks clear guidelines for storing, sharing, and editing data.
Common limitations and risks include:
Critical data is accessible more broadly than necessary: Whoever receives a file may see multiple types of data, including selling prices, costs, and profit margins, even when some of it is unrelated to their role.
Multiple file versions lead to inconsistent data: Each department may use a different set of data, affecting decisions and collaboration.
Changes can't be fully traced: If files are edited separately without an appropriate tracking system, it can be hard to identify who made a change and what exactly was changed.
Access can't be revoked thoroughly: When employees change roles or leave, copies of files that were already forwarded may still exist.
Unclear segregation of duties: If one person can both prepare and approve critical transactions without appropriate controls, the risk of errors and fraud may increase.
As a business grows, managing these risks should therefore evolve from controlling files case by case to systematically defining permissions and work processes.
How Does SAP Business One Help Control Permissions and Critical Data?
SAP Business One offers capabilities for defining user permissions, controlling access to certain types of data, approving documents, and reviewing change history, which help support an organization's internal controls.
1. Assign User Permissions by Responsibility (User Authorizations)
Organizations can define access to menus, functions, and various actions for each user according to their responsibilities — for example, allowing use, allowing edits, or restricting access to functions unrelated to their role.
Appropriate permission settings help reduce unnecessary access to data and unnecessary actions. That said, permissions need to be designed to cover real-world usage, not defined solely by job title.
2. Restrict Document Access by Data Owner (Data Ownership)
SAP Business One supports permission management based on data ownership for certain types of documents and data, depending on the capabilities the system supports and the organization's configuration.
This approach helps restrict data access between users or user groups in finer detail where appropriate — for example, controlling access to documents associated with each responsible person.
However, restricting visibility of every type of data, such as costs or profit margins, may require additional permission settings and consideration of related usage patterns.
3. Control Transaction Approvals (Approval Procedures)
Critical transactions should have approval steps appropriate to their level of risk — for example, setting conditions so that purchase orders meeting certain criteria must be approved before proceeding.
SAP Business One supports Approval Procedures, which help define conditions and approvers according to the process an organization designs. This makes approvals more systematic and reduces reliance on following up through email or chat alone.
That said, approvals are most effective when defined together with user permissions and appropriate segregation of duties.
4. Review Change History (Change Log)
When data or documents change, reviewing the history helps an organization understand the changes the system has recorded — such as details before and after an edit, along with who made the change and when, as far as the system supports.
SAP Business One offers a Change Log function for supported data and documents, helping support retrospective review and internal checks.
Organizations should verify the scope of data that can be recorded and the related settings, so that they align with their review objectives, and should not assume the system automatically records every type of activity.
5. Use Data from a Central System, Reduce File Duplication
SAP Business One helps departments work with business data from the same system database, reducing reliance on multiple versions of Excel files when passing data between departments.
Users can access data and produce reports according to the permissions they've been granted, helping Sales, Purchasing, Accounting, and executives work more consistently with one another.
However, exporting or copying data out of the system may still be possible depending on user permissions, so organizations should also have a policy controlling how data is taken out of the system.
6. Manage Permissions When Personnel Change
When employees change roles or leave, system administrators can adjust or deactivate user accounts and review related permissions from the central system.
Having a clear procedure helps reduce the risk of unnecessarily retaining old permissions, and supports access control that stays aligned with each person's current responsibilities.
Example: Controlling Cost and Selling Price Data
When Excel Is Shared Across Multiple Departments
Sales, Purchasing, and Accounting receive files containing selling prices, costs, and profit margins. When multiple copies of a file are edited, an organization may run into inconsistent data, as well as incomplete tracking of access and changes.
When Using SAP Business One
An organization can design permissions to fit each department's responsibilities, define approval steps for critical transactions, and use data from the central system to produce reports, while considering how to restrict access to each type of data according to supported capabilities and configuration.
The desired outcomes are less data duplication, clearer division of responsibilities, and a more systematic way to review how work is done.
6 Steps to Structure Permissions in SAP Business One
Defining appropriate permissions should start with understanding how the organization actually works, in 6 steps as follows:
Step 1: Survey Users and Their Responsibilities
Identify all users, along with the roles and transactions each person needs to perform according to their actual duties.
Step 2: Classify Data by Importance
Separate data that requires special control — such as costs, profit margins, and personnel data — from general-use data.
Step 3: Prepare a Permissions Table (Role Matrix)
Define the permissions needed for each role, while checking segregation of duties and access to data beyond what's necessary.
Step 4: Define Approval Steps and Review Requirements
Design approval conditions for transactions and determine which data needs to be reviewable after the fact, in line with the organization's risk level.
Step 5: Test with Real Scenarios and Train Users
Test that each role works according to its assigned permissions — neither too much nor too little — and train users before going live (Go-Live).
Step 6: Review Permissions Regularly
Set a review cycle for permissions, and update them when personnel, processes, or organizational structure change.
Data Security Requires Both Systems and Processes
Although SAP Business One helps support permission control and data review, effective security management also requires other measures, including:
Clear data access policies and designated owners
Security of servers, networks, and user accounts
Data backup and restore testing
Guidelines for controlling data exported from the system, such as exports to Excel
Organizations that store personal data should consider the relevant legal requirements, including the Personal Data Protection Act (PDPA), and assess the necessary measures together with the personnel responsible for legal or personal data protection matters.
