LSMW-material master-convert data step problem

Hello Abapers,

I am trying to upload material master thru direct input method(LSMW).My source structure has the following fields:

MATNR,MBRSH,MTART,MAKTX,MEINS.

<b>1Q</b>.To what all target structures(BGR00,BMM00,BMMH1,BMMH2,...BMMH8) do we assign the source structures??

<b>2Q</b> If i have to select any views...do I need to assign constant value 'X' to the target structure field or I should maintain those values in my legacy data??

<b>3Q</b> What are the different timezones in LSMW???

Thanks,

Anky
