Loading a User-Based Default Variant for SAP Reports
When creating reports in SAP, it’s common for users to have personal preferences regarding the selection screen layout. A feature that loads a predefined user variant upon report initialization can significantly enhance the user experience. This allows the report to automatically load the user-specific variant without requiring manual input. In this blog post, I’ll walk you through how you can easily implement this functionality using a simple ABAP code snippet.
🎯 Objective: Automatically Load User Variant on Report Initialization
The goal of this implementation is to load a default variant (U_<sy-uname>) when a report is initialized, ensuring that users always start with their predefined settings. The variant is linked to the user’s SAP username (sy-uname), making this a dynamic, user-specific feature.
You can achieve this by using the function module RS_SUPPORT_SELECTIONS in the INITIALIZATION block of your ABAP report. This function helps load the selection screen variant based on the user’s SAP system username.
📝 Code Snippet for Loading User Variant
To make this feature reusable across multiple reports, we can encapsulate the logic into an include, which can then be added to any report. Here’s the basic code for loading a user-specific variant:
1. Create an Include: ZCA_DEFAULT_VARIANT
This include will hold the code to load the user variant. Here’s the code for the include:
1
2
3
4
5
6
CALL FUNCTION 'RS_SUPPORT_SELECTIONS'
EXPORTING
report = sy-repid
variant = CONV rsvar-variant( |U_{ sy-uname }| )
EXCEPTIONS
OTHERS = 0. " just to ignore if there is no variant
The code essentially does the following:
- report: Passes the current report ID (
sy-repid). - variant: Constructs the variant name dynamically using the user’s username (
sy-uname), e.g.,U_JOHNDOE. - EXCEPTIONS: Catches any exceptions that may occur if the variant does not exist, allowing the program to proceed without error.
🛠️ Implementing the Include in Your Report
Once you’ve created the ZCA_DEFAULT_VARIANT include, you can easily integrate it into any report that requires this functionality. Here’s how you can add it to your report:

* INITIALIZATION

INCLUDE zca_default_variant.
...
Simply include zca_default_variant in the INITIALIZATION block of your report, and the user-specific variant will be automatically loaded when the report is run. This makes the feature reusable across multiple reports with minimal effort.
🤔 Why Use This Approach?
This approach offers several advantages:
- User Personalization: It helps personalize the report by loading settings specific to each user.
- Improved User Experience: Users don’t need to manually select their preferred variant each time they run the report, leading to a more streamlined experience.
- Reusability: By placing the logic in an include, you can easily reuse it across multiple reports, saving you time on repetitive coding.
🧠 Final Thoughts
Implementing user-specific default variants in SAP reports is a simple yet powerful way to improve the user experience. By using the RS_SUPPORT_SELECTIONS function module, you can easily load a predefined variant for each user, making your reports more efficient and personalized. Whether you’re developing custom reports or enhancing standard ones, this approach will save you and your users valuable time.
Feel free to integrate this approach into your own reports, and don’t hesitate to experiment with different user variant management strategies for even more customization!
Happy coding!
