Authorization object for Movement type

Hi Experts,

We there are 5 authorization object for Movement types. These are at below:

Reservations: Movement Type :  M_MRES_BWA

Material Documents: Movement Type : M_MSEG_BMB

Goods Movements: Movement Type :  M_MSEG_BWA

Goods Receipt for Purchase Order: Movement Type : M_MSEG_BWE

Goods Receipt for Production Order: Movement Type :  M_MSEG_BWF

In application transactions like MIGO, MB01 we need to put the movement types. But I need to know which authorization object is using for a particular option? As there are many options in MIGO

If i want to restrict an user for particular option, then which authorization object to be used. How to know it?

Please help me.
