We are all familiar with the "Patterns" button in the ABAP Editor which helps us to generate templates for function modules,classes and standard SAP Objects.In this blog I would like to talk about creating our own dynamic patterns in the ABAP Editor and calling it via the "Pattern" button.In this blog I will explain how to create a dynamic pattern for the "TYPES" statement in ABAP.

3. Test Program calling the pattern
Create a program in SE38.Click on the
Pattern
button and select theOther pattern
radio button.Enter the pattern created by you in the input box and press ENTER.The following popup screen will be displayed.
The following features are possible in this application.
1.You can include another type within your type by inputting the "Include Type" name.
2.Entering the table name and clicking on the "LIST" button will populate the fieldnames of the table along with their data elements.
3.You can edit the fieldnames as per your requirements.Clicking the 'ADD" button below the ALV grid will add the fields to the type.The "UNDO" button will clear the fields added to the type.
4.Clicking the "CONTINUE" arrow will insert the generated type within your program.
5.Clicking the "CANCEL" cross will exit the popup box and clear the selection.
A sample test program is as shown below .
You can transport your created pattern by clicking on the "Transport" option in the pattern editor
