sold-to-party default partner id map for customer field in SMCR - ChaRM 7.1

Hi Expert,

I am trying to map sold-to-party partner id default in SMCR- CRM screen (when Request for Change screen open) .

In IB52 ->Goto -> Partner , i gave sold-to-party details.

but its not reflecting in Request for Change screen open in CRm_UI.

Rg,

Karthik
