How to Convert Timestamps in SAP BW/4HANA Data Loads Using AMDP Code

How to Convert Timestamps in SAP BW/4HANA Data Loads Using AMDP Code

Timestamps are data elements that represent a specific point in time, such as 2021-01-31 23:59:59. Timestamps are often used in SAP BW/4HANA to track the changes and events in business data, such as sales orders, invoices, deliveries, etc. Timestamps can also be used for analytical purposes, such as calculating durations, intervals, aggregations, etc.

However, timestamps can also pose some challenges when loading data into SAP BW/4HANA, especially when the source and target systems have different formats or time zones. For example, if the source system uses UTC (Coordinated Universal Time) and the target system uses CET (Central European Time), you need to convert the timestamps accordingly to avoid inconsistencies or errors.

In this blog post, we will show you how to convert timestamps in SAP BW/4HANA data loads using AMDP code. AMDP stands for ABAP Managed Database Procedures, which are database procedures written in ABAP and executed on the SAP HANA database. AMDP code can help you process and transform data faster and more efficiently than ABAP code.

Why Use AMDP Code for Converting Timestamps?

There are several reasons why you may want to use AMDP code for converting timestamps in SAP BW/4HANA data loads:

  • AMDP code can run directly on the SAP HANA database, which means it can leverage the parallel processing and in-memory capabilities of SAP HANA. This can improve the performance and scalability of your data loads.
  • AMDP code can access and manipulate data from different sources and targets, such as tables, views, InfoObjects, etc. This can give you more flexibility and control over your data transformations.
  • AMDP code can use SQLScript, which is a scripting language for SAP HANA that supports advanced features such as functions, expressions, conversions, etc. This can make your code more readable and maintainable.

How to Use AMDP Code for Converting Timestamps?

To use AMDP code for converting timestamps in SAP BW/4HANA data loads, you need to follow these steps:

  1. Create an AMDP class and method that contains the logic for converting timestamps. You can use the example code below as a reference. The code uses the TO_TIMESTAMP function to convert a string value into a timestamp value with a specified format. It also uses the ADD_SECONDS function to add or subtract a number of seconds from a timestamp value based on the time zone difference. The code also checks if the input value is valid and returns an initial value if not.
  1. Create a transformation that uses the AMDP class and method for converting timestamps. You can use the transformation editor in SAP BW/4HANA to create a transformation between your source and target objects. In the transformation, you need to call the AMDP method for each field that contains a timestamp value. You can use the example code below as a reference. The code passes the field value, the format string, and the time zone difference as parameters to the AMDP method.
  1. Execute the data load and check the results. You can use the InfoPackage or the Data Transfer Process (DTP) to execute the data load from your source object to your target object. You can also monitor the data load status and logs in SAP BW/4HANA. After the data load is completed, you can check the results in your target object and verify that the timestamps are converted correctly.

Conclusion

In this blog post, we have shown you how to convert timestamps in SAP BW/4HANA data loads using AMDP code. AMDP code can help you improve the performance, flexibility, and readability of your data transformations. We hope you find this blog post useful and informative.
