I'm new to SAP and HCM in particular. I am working on this project where I'm leading a PD module, with the integration with the other modules mentioned.
I was wondering how popular and marketable this modules are, since all I see is mostly about PY, TM, ESS/MSS. I know that at the end, all of them are integrated and should develop knowledge on them, at least for integration purposes.
Is it a good investment to specialize on these, or you guys recommend PY/TM more.
Thanks for your thoughts,
