How to Improve Data Management and Performance with Partitioning in ADSO in SAP BW/4HANA

SAP BW/4HANA is a modern data warehousing solution that enables you to integrate, transform, and analyze data from various sources. One of the key challenges of data warehousing is how to manage the data volume, cost, and performance efficiently. This is where partitioning comes in handy.

Partitioning is a feature that allows you to split the data stored in the Advanced DataStore Object (ADSO) into smaller units based on certain criteria, such as characteristics or time periods. Depending on these criteria, the data is stored in different physical database tables or partitions.

Partitioning can help you to achieve the following benefits:

• Better performance and parallel processing. Partitioning enables the data transfer processes (DTPs) to extract and load data in smaller data packages based on the partition values. This allows for faster data transfer and parallel processing of multiple data packages.
• Better error handling and troubleshooting. Partitioning enables the DTPs to write the error stack based on the partition values. If an error occurs, the DTP writes all records with the same partition value to the error stack, regardless of whether they have errors or not. This ensures that the records do not get out of order when using the error stack. The error stack can be used to correct or delete the incorrect records later.
• Better reporting and analysis. Partitioning enables the queries to access and aggregate data in smaller units based on the partition values. This ensures that the queries are executed faster and more efficiently.

In this blog post, we will explain what partitioning is, how it works, and how to use it in SAP BW/4HANA.

What is Partitioning?

Partitioning is a feature that allows you to split the data stored in the ADSO into smaller units based on certain criteria, such as characteristics or time periods. Depending on these criteria, the data is stored in different physical database tables or partitions.

Partitioning can be applied either on semantic level or on database level. On semantic level, you can create semantic partitions based on characteristics that have a logical or business meaning for grouping the data, such as regions, product categories, or customer segments. Semantic partitions are used to create semantically partitioned data models, such as Semantically Partitioned Objects (SPOs) or Semantic Groups (Semantically Partitioned ADSOs). Semantic partitions are also used for error handling purposes.

On database level, you can create database partitions based on characteristics that have a technical meaning for distributing the data, such as time characteristics (0CALDAY, 0CALMONTH etc), document numbers, transaction codes, or customer IDs. Database partitions are used to optimize the data storage and performance of your ADSO by leveraging the capabilities of SAP HANA database.

How to Use Partitioning in SAP BW/4HANA?

To use partitioning in SAP BW/4HANA, you need to follow these steps:

1. Enable partitioning in the Settings tab of your ADSO. Under Partition Properties, you can choose whether to partition your data by semantic groups or by database partitions.
2. Choose the method by which you want to define the partitions for your ADSO. You can choose either on semantic level or on database level.
3. If you choose on semantic level, go to the Settings tab of your ADSO and create semantic groups based on characteristics by which you want to group your data. For each semantic group, provide a lower limit and upper limit for the characteristic value. Then assign different DTP settings for each semantic group based on your requirements.
4. If you choose on database level, go to the Settings tab of your ADSO and define database partitions based on characteristics by which you want to distribute your data. For each database partition, provide a lower limit and upper limit for the characteristic value.
5. Activate the changes in your ADSO. This will generate the metadata and partitions for partitioning in SAP BW/4HANA.
6. Run the DTPs and monitor the data load in the DTP monitor. If errors occur, you can check the error messages and the error stack in the DTP monitor. You can also use an error DTP to correct or delete the incorrect records in the error stack.
7. Run the queries and monitor the query execution in the query monitor. You can also use query tools such as RSRT or RSRT2 to analyze and optimize your queries.
