EWM standard RF logic transaction code and step introducing

[shuming]

Dear expert,

Is there any SAP official document to descript EWM standard RF logical transaction code and step.

I find it is difficult to understanding each functionality of each logical transaction code and step without document.

there are a lot of standard function which can be used in SAP project implementation. Now I only can discover it by a lot of testing and read coding directly.

Thanks a lot.
