Popup Message in SRM 7.0

Hi All,

I am working on SRM 7.0 . I am trying to show a pop up after adding items to the shopping cart after a validation. I made the validation in the badi ZBBP_CATALOG_TRANSFR. I need to pop up a message after that .

I have used he FM BBP_PD_MSG_ADD in the ZBBP_DOC_CHECK badi and I am getting the message but I need a pop up message.

Please suggest on how it could be acheived.

Thanks in advance

Sudha.
