Credit Memo and Replacement Qty are not appearing in Return to Supplier Business Object

[Former Member]

Hi.
I am working on SAP Business By Design. My client is creating report using Return to Supplier Data Source provided by SAP. In this Data Source, Replacement Qty and Credit Memo Qty are not appearing separately. They are appearing as a Sum for a single line in a single field. My client wants it separately.
I am creating a new Data Source using SAP Cloud Application Studio 1708. I select Purchasing as Namespace and Return To Supplier as Business Object as show in Fig.
When i click next the only Quantity field appears in Return to Supplier Business Object as shown in Fig. I want to select these quantities also. What should i do. Please help. Thanks
