Pass Selection screen parameters of VL10c to User exit program

Hi Team,

Few selection screen parameters are provided in the VL10c program which runs in background.

IF the VL10c runs in the background, based on few conditions from selection screen and few custom tables...I want to set the Delivery block during Delivery creation...as VL10c does the same.

I want to collect the Selection screen parameters values and validate in user exit of delivery...request to provide me suggestion on the same.

Setting the Delivery block is fine but not able to fetch the Selection screen values in user exit.

Regards,
