I found some minor findings (see my comments). But I think that the AFF structure needs to be changed nearly completely. Maybe we can have a call and talk about it.

Please expect a delay for the review of this pull request. We have to clarify the language dependent fields of this object.

Thank you for submitting your object type to the AFF Repository. After detailed discussion with @wurzka @schneidermic0 please go over my comments above and solve them. Please also solve the abaplint issues.

As we discussed in a previous meeting, please remove the ty_template_content, in order to put the language parts into separate files.

Thanks for updating the AFF. I've added some new comments with some optional suggestions that are up to you to decide.
If you have any questions regarding my comments, feel free to reach out.

Thank you for the feedback. I changed the requested lines and uploaded the updated documents.

Hi, thank you again for adapting our suggestions. One more question from our side:

Edit: Please also sign the Contributor License Agreement as described in #633 (comment) to make all automated checks happy.
