FM ISU_S_CONNOBJ_CHANGE is not updating Connnection Object in Background

Hi Experts,

I am trying to update connection object using FM ISU_S_CONNOBJ_CHANGE in background mode. But Its not getting Updated. Before calling this function Module I am calling ISU_S_CONNOBJ_PROVIDE to get Y_OBJ and Y_AUTO, which I am passing to

ISU_S_CONNOBJ_CHANGE.

Regards,

Pradeep
