Net & Gross weight issue

Hi All,

I am facing an issue with the Net weight & gross weight in the Invoice. Kindly see the issue in more detail.

Third party sales order for customer.

1) The Sales order capture the net weight & gross weight  from article master based on the ordered qty.

     Let say for Example: Article "A" , Net weight (2 Kg per PC) & Gross weight (3 Kg per PC) in article master. Ordered Qty 10 PC, Therefore in Sales Order Net weight (20 KG) & Gross weight (30 KG).

2) Based on the third party Sales order, A Purchase order is created and send to Ext. Vendor and followed by Delivery order, Vendor will do pick & Pack& Weightthe actual Order Qty. Let Say (Net weight- 15 KG) & (Gross weight- 18 KG) & deliver it to the  customer.

3) Vendor invoice the us based on the Actual Net & Gross weight of the ordered Qty printed on the Invoice copy but we invoice the external customer based on the invoice created from Sales Order which reflect the wrong Net weight (20 KG) & Gross weight (30 KG). For Custom purpose, It is required to declare the correct Net weight & Gross weight in the Invoice.

Please suggest a suitable solution..

Thanks & Regards
