Standard Ship To Address modified

Hi,

We have a requirement as -

While creating a Shopping Cart, the Ship To address (Delivery Point - Partner Fct - 27) is getting picked up from the Standard

Ship to Address maintained against the Purchasing data. Now if a user modifies the Ship To Address while creating the Shopping Cart, we should be able to catch that when we use the standard Function Module BBP_PD_SC_GETDETAIL to retrieve the Shopping Cart data.

My query is - how can I understand whether an user has modified the standard Ship To Address through BBP_PD_SC_GETDETAIL or using transaction BBP_PD?

Thanks in advance.
