Equipment No ( Serial no ) to Credit or debit memo

Hi ,

In our project we are creating Credit or debit memos in ECC for the Sevice Confirmation in SAP CRM. We are able repliate these well.

we have one issue, we are not able to link thse Credit or debit memow with the Equipment no or Serial no. Which we can see in Extras of the Transaction.

Experts please throw some light on this.

thanks ,
