When you Subscribing to Feeds from ABAP Repository, you can define rules to choose the ABAP runtime errors that you want to see.
If you do not define a filter, the feed reports all runtime errors that occur in the ABAP project.
You can quickly and easily define identical feeds for runtime errors in your ABAP Projects. To do so, just set up one feed as you wish to have. Then choose Copy query selection to clipboard at the bottom of your selection specifications.
Now create a new runtime error feed or choose Edit feed... for an existing feed. On the Feed Query Configuration dialog, choose Paste query selection from clipboard. The ABAP Developer Tools take over the configuration that you copied for the new feed.
