Requirements and Installation

To install and use the ABAP cleaner plug-in for ABAP Development Tools (ADT) on Windows or macOS,

  1. Install ABAP Development Tools as described in the Install ADT Tutorial (Step 1), using an Eclipse installation that is compatible with ADT.

  2. Start ADT, select the menu ‘Help / Install New Software…’, copy the link to the ‘Work with’ field, and follow the installation steps, confirming to install ABAP cleaner. (Known issues)

After restarting ADT, open an ABAP code document in an editor, and use the menu ‘Source Code / Clean Up With Interactive ABAP Cleaner…’ (shortcuts Ctrl + 4 or Ctrl + Shift + 4),

If you select the first option “Clean Up with Automated ABAP Cleaner” it will automatically clean up the code based on the profile we have set up.

If you select the second option “Clean Up with Interactive ABAP Cleaner” here we can select the rules that we want to reflect in our code and here we have many options.

If we already created the profile, we can directly click on the “Save and Applybutton to apply the desired rules to be applied.

If we want to create a profile we need to click the configure button on the right corner.

On the top left in the profiles section we can Create, Copy, Delete, Import, and Export profiles.

On the bottom left in the rules section, we can check the checkbox that should clean up our code.

If the selection of rules is completed then click on the “save profiles and exit” button on the bottom right.

So, now we are set to give it a try.

In summary, the ABAP Cleaner tool is a valuable tool for automating the clean-up of ABAP code, ensuring uniformity, reducing errors, promoting modernization, fostering collective code ownership, and improving maintainability.
