Different price value in CRM and ECC

Hi Experts,

I have a sales order created with third party item in CRM the same is replicated to ECC.

in header for sales order(Order is in complete authorized status)  net value is 184$ but at item level the value of product in 441 which is also same replicated to ECC.

I checked in CRMD_ORDER also I can see 184$ net price is there .

Is there any idea why it is showing different total in header and item level.

Regards
