Understanding the Challenge of Retrieving Values from the /AIF/ERR Variant

In the world of ABAP programming, developers often face challenges while trying to access specific values from complex transaction variants. One common issue arises when trying to retrieve values from the /AIF/ERR transaction variant. Many developers have struggled with capturing elements like the name space, interface, and interface version related to this transaction. In this guide, we will explore the problem and provide detailed steps on how to effectively retrieve the data you need.

The Problem Defined

Your goal is to access specific values tied to the /AIF/ERR variant. While you've made some progress by using function modules like RS_VARIANT_CONTENTS and RS_VARIANT_VALUES_TECH_DATA, you found that crucial information such as the name space, interface, and interface version were still elusive. After researching tables like VARI* and TVARC, you realized they did not have the required data, leading to more confusion.

Key Considerations:

The target values are dynamic and depend on selections made in the Application screen field.

These values aren't stored within the program variant.

They can be handled by a different AIF program.

A Clear Solution

The good news is that there are established methods for obtaining the missing parameters, specifically through the utilization of the /AIF/T_ERR_VARS table and corresponding function modules.

Step 1: Understand the Data Source

The values you're looking for (i.e., name space, interface, interface version) do not reside where traditional data might be found. Instead, they are dynamically retrieved and saved in the table:

Table: /AIF/T_ERR_VARS

Step 2: Utilize the Correct Function Module

To initialize and load the missing parameters, you can utilize the function module:

Function Module: /AIF/ERR_VAR_LOAD

How to Use It

The usage of this function module is often demonstrated in the subroutine GET_VAR within the AIF program, specifically:

Program Name: /AIF/ERROR_HANDLING_TRANS

By referencing this program, you can directly access how parameters are set and how the function module can facilitate the retrieval of the values you seek.

Conclusion

Retrieving values from the /AIF/ERR variant can initially seem overwhelming due to the nature of the dynamic data and its storage. However, by understanding the role of the /AIF/T_ERR_VARS table and utilizing the /AIF/ERR_VAR_LOAD function module, you can effectively access all the necessary parameters.

If you encounter additional questions or need further assistance, feel free to reach out to the ABAP community or explore further documentation related to AIF transactions.

Happy coding!
