Modify Data Structures and Fields

Let’s first create a sample message to showcase the customizing changes.

1. Open the Test Tool for IDoc Processing (transaction code WE19).

2. Send in a new test message with an empty customer name and a wrong customer type (for example, change CUSTTYPE to Q) to force an error.

   

3. In SAP GUI, check the results of your test in the Interface Monitor (transaction code /n/AIF/IFMON).

   When you select the summary line for your interface, you’re forwarded to Monitoring and Error Handling, where you can see your selected test message. Choose the Error icon to display the respective message. The message should be in status Error with the message texts Customer type can be only B or P and No customer name specified.

   The fields and structures that are highlighted in the following screenshot will be impacted by the customizing changes carried out in this tutorial.

   

Since you want to edit fields that contain wrong or even no data to be able to fix the errors caused by the wrong data, you need to define changeable fields.

1. Go to Customizing for SAP Application Interface Framework (transaction code /n/AIF/CUST) and navigate to Error Handling > Define Interface-Specific Features.

2. In the upcoming dialog, enter namespace DEMO_1, interface FCUSTOMER, and version 1, then press Enter.

3. Double-click Define Changeable Fields in the menu on the left. Add a new entry with Index number 10 and Field Path E1SCU_CRE-E1BPSCUNEW-CUSTTYPE.

4. Add a new entry with Index number 20 and Field Path E1SCU_CRE-E1BPSCUNEW-CUSTNAME.

   

5. Save your changes.

As a next step, you want to hide a structure that is empty anyway.

1. Stay in the Define Interface-Specific Features customizing activity and double-click Hide Structures in the menu on the left.

2. Add a new entry with Field Path E1SCU_CRE-E1BPPAREX.

   

3. Save your changes.

Now, you also want to hide a field that contains sensitive data.

1. Stay in the Define Interface-Specific Features customizing activity and double-click Hide Fields of Structure in the menu on the left.

2. Add a new entry with Index number 10 and Field Path E1SCU_CRE-E1BPSCUNEW-EMAIL.

   

3. Save your changes.

You want to rename the labels of the data structures and fields.

1. Stay in the Define Interface-Specific Features customizing activity and double-click Define Structure Labels in the menu on the left.

2. First, let’s rename the structure label.
   Add a new entry. For the Component Name, select the Field Path E1SCU_CRE-E1BPSCUNEW. The Component Name is now ZDEMO_1_00000021. Enter Customer Data as Description, Medium Text, and Long Text, and Data as Short Text.

   

3. Next, let’s rename the label of the customer name.
   Add a new entry. Select the same Component Name ZDEMO_1_00000021 as before and the Component Field CUSTNAME. Enter Customer Name as Description, Medium Text, and Long Text, and Customer as Short Text.

   

4. Finally, let’s rename the label of the form of address.
   Add a new entry. Select the same Component Name ZDEMO_1_00000021 as before and the Component Field FORM. Enter Form of Address as Description, Medium Text, and Long Text, and Form as Short Text.

   

5. Save your changes.

Now, let’s test that the customizing we configured works as planned.

1. Reopen the Monitoring and Error Handling. You should still see the message in status Error.

   If you opened Customizing in a new screen, you might have to restart Monitoring and Error Handling for the changes to be visible.

   You’ll notice that the structure E1BPPAREX is not displayed and that the structure and field labels have been changed accordingly. If you scroll to the right, you’ll notice that the field containing the email address is not displayed either.

   

2. Double-click the Customer Name field, and maintain any customer name, then choose Confirm.

   

3. Maintain a valid value for the field CUSTTYPE (either B or P), then choose Confirm.

   

4. Save the changes and Restart the data message. It should now process without errors.

Congratulations! You’ve successfully customized the data structures and data fields.
