Hi All,

I have requirement to check the field data in SRM 7.0, but the data which i need to check is in backend (R/3 system) system.

So is there any PDO classes concept in which i can read that data reated to that shopping cart.

I am not aware of what this PDO classes is, So can some pls let me know how this can be achieved ?

Thanks & Regards,
