Semantic analysis of ABAP code

Is there anything similar to code2vec or cuBERT for ABAP? I would like to analyse the semantics of ABAP Source code with machine learning techniques and I'm curious if there are any projects in this direction.

Do you have any recommendations where I could find a large amount of well written and commented abap code for the dataset?

Are there any similar projects for extracting labels or keywords from abap source code?
