SRM 7 Shopping cart change tab/field on condition

Hi Experts,

We have requirement for authorization for change of shipping address on basis of condition . If plant number is XXXX than user can able to edit data in ship to address data ( Delivery address/performance location).

AS SRM 7 is on WebDynpro application the change badi is not getting trigger and also we can no do configuration by POWL as it required on condition basis.

Please reply

Thanks
