Hi Hasan,
I am new to Oracle Financials. Luckily I have been able to grasp most of the concepts covered in your video tutorials.
I tried to read through GL module first. But after a while, there are other concepts covered in AP( Say Multi-Org).
How should I toggle between the tutorials here? Please guide me here. I would really appreciate it.

Thanks in Advance,
Mini

As a rule of thumb, if you complete all modules (categories: GL, AP etc) in sequence you will be all set.
That is how the training program is designed.
For example,
Videos in AP assume you have setup your ledgers in GL sessions.
Videos in AR assume you have created your bank account in AP sessions.
There is one minor exception in GL videos. When you will come to mass allocations you will notice that you will get an error because no operating unit is assigned to your GL responsibility. This issue was overlooked by me while designing the sequence and was pointed out by the members.
You have few choices at this point.
1) You can go through first 18 videos in AP at this point, to create an operating unit and assign it to your GL responsibility.
2) Skip the mass allocation exercise for now and come back to it once you have completed 18 videos in AP.
