SalesPrice in SalesOrder is falling to Zero before invoicing.

Hello,

I am facing a strange issue with the sales order. I created a sales order and and also Purchase order to it,I invoiced the PO(Purchase Order) of this sales order and when trying to invoice the sales order The sales price on sales order is showing as empty. Can any one of you have ever faced this issue before? If so please help me ,this was happening in our production server.

Thanks In advance!!!

No not seen this before.

Purchase order from the sales order?

Direct Delivery purchase order from the sales order?

Intercompany?

Which Version of AX?

What is the line cost on the purchase order irrelevant of the invoice?
