Invoice Exception: Invoice has reached the soft limit. Billing amount may exceed funding limit.

Hi Experts

I have generated a draft invoice for 60000 containing 2 lines of 25,000 and 35,000 respectively. 

When I interfaced this invoice to AR, the invoice is interfaced and I can see "Accepted in Receivables" status in Invoice review of Projects. But, when I checked the AR invoice, I can see only 25,000 as the invoice amount with the first line of 25,000 and the second line is showing 0.

When I checked in the invoice review window, under the Invoice Exception Tab, it is showing a warning message as "Invoice has reached the soft limit. Billing amount may exceed funding limit." Please help me out in fixing this issue.
