Add serial number for the existing Item in Quotation using CRMXIF_ORDER_SAVE

Hello All,

I am using the function module 'CRMXIF_ORDER_SAVE' to update the quotation. I was able to create an item for a quotation. Now I want to add one more serial number to the existing line item.

I tried filling the reference object structure. But this was not creating a record. Instead I am getting a duplicate records short dump on PRODUCT_I table.

Please suggest me how to add one more serial number to the existing line item record using 'CRMXIF_ORDER_SAVE'.

Thanks,

Kishore.
