How to Load Data from Composite Provider to ADSO in SAP BW/4HANA: Scenarios and Solutions

How to Load Data from Composite Provider to ADSO in SAP BW/4HANA: Scenarios and Solutions

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 features of SAP BW/4HANA is the Composite Provider, which allows you to combine data from different InfoProviders, such as Advanced DataStore Objects (ADSOs), Open ODS Views, or SAP HANA views, into a single logical view.

Composite Providers are useful for creating flexible and complex data models that can leverage the capabilities of SAP HANA database. However, sometimes you may need to load data from a Composite Provider to an ADSO for various reasons, such as:

  • To persist the data from a Composite Provider for reporting or analysis purposes.
  • To apply further transformations or calculations on the data from a Composite Provider.
  • To perform error handling or delta load on the data from a Composite Provider.

In this blog post, we will explain how to load data from a Composite Provider to an ADSO in SAP BW/4HANA, and provide some scenarios and solutions for common challenges.

Loading Data from a Composite Provider to an ADSO

To load data from a Composite Provider to an ADSO in SAP BW/4HANA, you need to follow these steps:

  1. Create an ADSO that matches the structure and semantics of the Composite Provider. You can use the template option in the ADSO editor to copy the structure from the Composite Provider.
  2. Create a Data Transfer Process (DTP) that connects the Composite Provider as the source and the ADSO as the target. You can use the DTP wizard to create the DTP automatically.
  3. Define the DTP settings, such as extraction mode, error handling, filters, transformations, etc., according to your requirements.
  4. Activate the DTP and run it to load data from the Composite Provider to the ADSO.
  5. 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.

Scenarios and Solutions

When loading data from a Composite Provider to an ADSO in SAP BW/4HANA, you may encounter some challenges or limitations, such as:

  • Only full load is possible from a Composite Provider to an ADSO. Delta load is not supported by default.
  • The performance of loading data from a Composite Provider to an ADSO may be affected by factors such as network latency, data volume, complexity of join conditions, etc.
  • The order of records in the ADSO may not match the order of records in the Composite Provider, especially when dealing with time-dependent or sequence-dependent data.

Here are some scenarios and solutions for these challenges:

Scenario 1: How to perform delta load from a Composite Provider to an ADSO?

Solution: You can use SAP HANA capabilities to find and load only the delta records from a Composite Provider to an ADSO. To do this, you need to create a calculation view that joins the Composite Provider (source) and the ADSO (target) based on key fields, and filters out only the new or updated records in the source. Then you can use this calculation view as a source in your DTP instead of the original Composite Provider.

For example, if you have a Composite Provider that combines data from two ADSOs based on customer ID and sales order number, and you want to load only the delta records from this Composite Provider to another ADSO, you can create a calculation view that joins these three objects based on customer ID and sales order number, and filters out only the records that have null values in the target fields (new records) or different values in the measure fields (updated records). Then you can use this calculation view as a source in your DTP.

Scenario 2: How to improve performance of loading data from a Composite Provider to an ADSO?

Solution: You can use partitioning techniques to split and distribute the data from a Composite Provider to an ADSO based on certain criteria, such as characteristics or time periods. Partitioning can help you improve performance by enabling parallel processing of smaller data packages.

For example, if you have a Composite Provider that combines data from different sources based on time characteristics (0CALDAY, 0CALMONTH etc), and you want to load this data to an ADSO, you can create partitions based on time characteristics in both your source and target objects. Then you can assign different DTP settings for each partition based on your requirements.

Scenario 3: How to preserve order of records when loading data from a Composite Provider to an ADSO?

Solution: You can use semantic keys to group and order data records in DTPs based on certain fields that have a logical or business meaning for ordering the data, such as time characteristics, document numbers, transaction codes, or customer IDs. Semantic keys can help you preserve order of records by ensuring that the records are updated in the target in the same order as they are extracted from the source.

For example, if you have a Composite Provider that combines data from different sources based on document number and posting date, and you want to load this data to an ADSO, you can define document number and posting date as semantic keys in both your source and target objects. Then you can enable semantic grouping in your DTP settings.

Conclusion

In this blog post, we have explained how to load data from a Composite Provider to an ADSO in SAP BW/4HANA, and provided some scenarios and solutions for common challenges. We have shown how to use SAP HANA capabilities, partitioning techniques, and semantic keys to perform delta load, improve performance, and preserve order of records when loading data from a Composite Provider to an ADSO.
