Hi team,

We are creating sales orders using the integration where we are using REST webservice to create sales orders in oracle. For bulk orders import, we might go for FBDI approach.

We are required to store quantity-based attributes in one sales order line which need to be searchable and need to be fetched in Reports also.

Example:- If a sales order is created for 1 line and 5 quantities(UOM=Each), then some of the attributes need to be accommodated for every quantity. Like those attributes should have values for respective quantities.
