I need to learn some MM transactions but I could not find any helpful techical document on these trans.
For example how to use MM01, when to provide a number for material or not to provide a matnr.
And step by step procedure to create a material.
Note: I am not asking MM01 transaction, it is just an example,
I need more trans to learn like MM01.
Please pay attention in posting that mostly used transactions be sent.
