Receipt Accruals not being imported in costing due to error "CCID for credit is invalid"

Hi Project Experts,

Please help me out in following issues.

I've created couple of Purchase Orders and completed the receiving process. And then ran the PRC: Interface Supplier Costs program and found neither my Purchase orders are picked up nor rejected by the program. I then switched to Costing application and looked into the import transaction screen. To my utmost, I am able to see all my purchase order which I am expecting to be imported into costing application. However they are all rejected due to the error message named "CCID for credit is invalid" You can see the screen shot attached.
