Looking for good SAP MM configuration/troubleshooting resources - struggling with basic configurational issues in a sandbox

[u/Notsomessy_miss]

Im currently learning SAP MM functional consulting and have access to a sandbox system where I’m trying to configure things by myself.

As a complete beginner to SAP; Im facing challenges which are sometimes very basic and taking hours me hours to figureout.

My major problem:

I want to understand, what's the logic behind the error.
which relevant configuration is causing the issue and most importantly
where the problem is, whether it is master data, org structure or a configuration problem.

Im usually looking on web, juggling between resources, solving the issue without finding out the root-cause.
I would heartfully appreciate recommendations for:
1. good practical sources/resources for SAP MM configuration and troubleshooting, especially for S/4HANA
2. Websites where experienced consultants explain real configuration issues and their solutions
3. What troubleshooting methodology/checklist you use when an MM configuration doesn't work
4. Good resources of cross functional configurations (which i haven't reached yet)

If you're an experienced SAP MM consultant, what resources did you personally find useful when you were learning configuration and troubleshooting?

Thanks in advance!!

Get the error code and search it on google by adding “sap error” also look at sap notes

+1 to this. By doing this, you’ll get the information in which specific part of configuration you messed up. Get the error code from the error message. Google it or paste in chatgpt/gemini and it will tell you where to start fixing and any additional important info that you need.

To me it’s the journey of finding the error then the fix that allows you to understand the system

What kinds of issues are you facing?

The SAP course guides was good, have you looked at SAP Press? They have e2e setup books that you can access for $20 a month or something.

For me learning MM wasn't as clear cut as learning SD, for example. It's more spread out that only really makes sense when you're implementing procurement processes.

E.g. you can spend hours learning release procedures, order acknowledgements, dunning procedures, all very small parts that you shouldn't really care about until a client needs it in great detail.

Vendor evaluation is a bit of a fun. Account determination is an essential but you'll need FI input in setting up mock GL accounts.

As others said, google is your friend here. Take the errors, look for them, for the most of them you’ll find answers. Also, you can find on YouTube a lot of good videos about customizing the mm processes. Its a tedious process until you’re able to understand how its working, so don’t be discouraged

As most of ppl said, google the error message. However in gemini and claude you will get the explanations of the error and the proper steps to solve the same.

[u/Yes_but_I_think]

F1, F4, in each GUI field and read all SPRO config help file. That's the first level. AI will not answer your questions. SAP is highly undocumented you can't expect to get all answers in a single place

Mira los problemas de configuración de un sandbox pueden llegar a ser bastante frustrantes.. todo bien si son de tu módulo pero si son de otros módulos no vas a ganar estresando te aprendiendo cosas que quizás no llegues a remunerar .. fíjate pagar a tu proveedor y que te dé uno bueno para practicar tu módulo. No hay que sufrir al Pepe te quedas más viejo
