Table VBBE - Inv scheduled for delivery

Hi all,

can anyone tell me what VBBE table is for. I want to pull data in this table to BW for infomation like "Inventory scheduled for delivery". I don't know the meaning of the fields like

material available date (MBDAT), VBELE, POSNE

some quantities like

OMENG, VMENG, UMREF

thanks,

Sabrina.
