Hi Muhammad
Interest and background and this is from the first post.
Sorry, I managed to mix up some of your question (multitasking failure)
I do know that SAP is a database,
However, SAP is not just a database. It is business application software. That is something that Google can assist you with (as you did mention in your original post "you don't know what's special about it". Also, if you are trying to get personal experience stories there have been quite a few posts in this space trying to get the same guidance.
'' I am interested in sales and would further like to go in that career field. Which SAP module will suit me best according to my future career field?
If you do search in here for SD or Sales and Distribution as well as CRM (Customer Relationship Management) you will find posts and careers advise for sales background. Some of the regular members in this space are from SD background.
The advise Michael gave you is only scratches the surface of what SAP is. That's the hard bit with SAP - it is such a big area and no-one can learn everything about it. One thing, you will always have a new topic and diversity if you are interested.
And how much will it cost? ''
For training costs, I recommend you look at authorized institutes. I'm not sure where you are from but if you do go to training.sap.com (SAP Education Site) for your local country you can get the contact details and for the Training office to discuss course options to suite your goals.
How can i study for SAP..is it must to go to a certified institution or i can buy books for this and study at home?
In relation to Certification you will also find that information on the site, including the prices. Again, depending on your country there may be additional rules to qualify for certification (India does for example). If you choose to go down the Sales pathway (Functional background in SD or CRM), you may also need to get some domain experience. As I am not a functional person, I am not in a position to comment there. It just means you might need to consider tertiary education in business area or work experience.
If price is an issue, you can also look at SAP Learning Hub subscriptions (also at Training) which is an annual subscription and grants you access to all of SAP's courses. You can then look at obtaining access to a system to practise on (search for IDES or SAP Learn Now). The downside of this option is your chance to be in a formal classroom and ask for assistance and connect with others (though SAP Learning Hub does have Learning Rooms to help prepare for certification).
i wanted to know things that werent on google and were experienced first hand by Sap consultants and users. Things that if they knew before doing Sap would have helped them.
My advise to you on this one - be prepared for the competition. You are right that a lot of companies are switching to SAP. However, they have been on their "SAP journey" for years. As a result, there are a lot of skilled workers in SAP competing for limited jobs. You will see such posts and questions on this space. With that, try not to take shortcuts to save money on training at a cost to job opportunities (again, it's a lesson some members have learned the hard way).
My own experience - there is always more to learn and whenever you find yourself in a new situation try to get your trainer to explain why the system works a certain way. You will go further in your career if you learn the fundamentals and not just the steps (too often people ask for step by step instructions without understanding the context)
Again, good luck
Regards
