@asgs overly simplified: locking problems. Or at least the exception that is thrown indicates it.

The "good" side is that nobody really cares since nothing seems to break in production, the code just suicides two or three times a day and no user notices that.
This is why I find it unlikely that I will find out what exactly is going on there anytime soon.

@kamen It would absolutely work just fine. Aside from business interests, I wanted to make private projects where I focus on the backend. If the appgyver solution provides a simple reliable front-end fast, I don't have to care about that for now.

If you are the smartest person in the room, you are in the wrong room.
I would not always advice to change the room right away, but it sure is a nice way of thinking.
Iam also not sure who the quote is from...

@mentalhijack its gonna be "interesting". The best piece of advice I can give you is that you should use the standard SAP/EWM functions whenever you can. They are sometimes impressively stupid but out of experience I can tell you that the Projects that mainly built Z-Solutions are all terrible.
Create new Tables/classes/transactions when there is no other way but dont do it because it seems convenient and easy.

Trust me, If you know SAP really well you are going to feel like a god (sometimes at least), because you are going to be one! (happens rarely and for a short time)

Edit: I red my old post again, much has changed xD

@copycat you clearly never worked with the infamous SAP GUI. You can develop in eclipse, but you will spend a lot of time in that GUI and there is nothing you can do to get a dark theme :D

@kimailis everybody hates it, but you have to do what has to be done...

I did that too, but just because it looked nice on paper.
Writing that you are a professional or intermidiate can also be a lie, so maybe you feel like progressbars are a better way of showing your skillevel.

Plus: whats written on paper does not have to reflect reality.
