14 Types of Charts in Data Visualization and When to Use Them
Every SAP BW system tells a story of growing data, evolving insights, and the constant challenge of keeping performance sharp. As data volumes surge, managing historical information becomes crucial to prevent sluggish systems and rising storage costs. A well-structured archiving strategy isn’t just a technical necessity—it’s the key to sustaining efficiency and reducing overhead.
For organizations implementing SAP BW (Business Warehouse), managing historical data efficiently is essential to keep systems running smoothly and cost-effectively. Without a clear archiving strategy, your BW system can quickly become overloaded, slowing performance and increasing storage costs.
An effective SAP BW archiving strategy helps you manage data growth, improve reporting speed, and ensure compliance with retention policies. The good news is it doesn’t have to be complicated. With the right approach, you can design a practical, easy-to-manage archiving plan that aligns with your business goals. Let’s look at six simple steps to build an SAP BW archiving strategy that works.
Step 1: Assess Your Current Data Landscape
Before you create an archiving plan, you must understand your current data situation. Start by analyzing how much data you have, where it resides, and how often it’s used. Identify which InfoProviders (such as DataStore Objects or InfoCubes) are growing the fastest and which ones are accessed rarely.
Ask questions like:
- How old is the data?
- Which reports depend on older data?
- Are there compliance or legal requirements for data retention?
This assessment will help you determine which data can be safely archived without disrupting day-to-day operations. Many businesses find that 60–70% of their BW data is historical and rarely needed for daily reporting. Recognizing this early helps you plan effectively and avoid archiving data that might still be useful.
Step 2: Define Your Archiving Criteria
Once you’ve analyzed your data, the next step is to define what and when to archive. Archiving criteria depend on business needs, reporting requirements, and data usage frequency.
You can set your criteria based on:
- Archive data older than a specific period (e.g., two or three years).
- Archive completed projects, closed fiscal years, or inactive customers.
- Some industries require you to retain data for a defined period before deletion.
Work closely with business stakeholders to agree on these rules. For instance, finance teams might want to keep five years of transaction data online, while logistics might only need the last two years. The goal is to create a balanced plan that satisfies both operational and compliance needs.
