Send data from one User Exit to other

Hi,

There are two User Exits in VA01 transaction

1.USEREXIT_MOVE_FIELD_TO_VBEP

2.USEREXIT_SAVE_DOCUMENT

The first Exit will get called for each line item while the second exit will get called at the time of saving.

For ex: According to my requirement I would like to store details of all the items.

Those details will be available only when the control is in EXIT1.And I need to acess all those details in EXIT2.

How we can do this?

Thanks in advance

Swathi
