Fiori : Sales Order Change App Error

Hi,

We have activated Sales Order change fiori app successfully. 

We have already maintained the config parameters & BADI implementation.

Upon clicking the Sales Order number in SO change app, it was displays the SO details.  When Change address button was clicked, it gives Edit window. When we click Next Button in Edit Sales Order window we are getting error "Partner function WE is not defined in partner procedure T ()".

Please let us know if anyone encountered this error

Thanks!
