I modified from the built-in RDLC 1306 sale invoice report layout, use a SUM in expression to calculate the total of the order line discount value. It work fine on the order I created manually. but showed #Error on order sync from Shopify. 
My expression involve 3 value from Dataset. I found for "LineDiscountPercent_Line" the Sum work fine on, but "UnitPrice" & "Quantity_Line" both can not get the Sum work in Shopify order. 
Could any one kindly help me locate the Error, and how to fix it.  
 
This is the expression:
Work fine on normal order:

    Thank you Khushbu Rajvi,
     
    I tried the code, it still only work on normal order I created manually, but showed #Error on Shopify order.
    I wonder are Shopify orders have different dataset structure.

    The #Error in the "Discount Total" field in your RDLC report could be caused by data type mismatches or handling of null values. Ensure that all fields like Unit Price, Quantity, and Line Discount are numeric, not text. To avoid errors, use an IIf condition in the expression to replace null values with 0.
    For example: =SUM(IIf(IsNothing(Fields!UnitPrice.Value) Or IsNothing(Fields!Quantity.Value), 0, Fields!UnitPrice.Value * Fields!Quantity.Value * Fields!LineDiscountPercent.Value)).
    Exporting the dataset can also help confirm the data integrity
