"Calculation failed; party not avaible" error when "Create Internal Settlement"

[S0010309815]

Dear Colleagues,

I´m trying create an internal settlement document for a Freight Order and the following error message appear when I select the option "Create Internal Settlement":

"....Calculation failed; party not available.."

The Freight Order does have the "Purchase Order" as well as the "Sales Order" (the one linked to an own vehicle resource which is being used to execute the Freight Order) .

An "Internal Settlement document type" has been assigned to the corresponding "Freight ORder Type"

Thanks in advance.

The real problem behind this error is the following:

At the time a Freight Order using a own vehicle resource is being used, and the option "Calculate internal charge" is selected, the costs are calculated correctly however, once the Freight Order has been saved, it loose internally (we have been debuging the program and we found the field "PURCH_ORG_ID" is with no value) the Purchasing Organization "Organizational Unit ID" and, due this reason, the error described on the previous blog appear.

Error message "........Calculation failed; party not available.."

Thanks

Gustavo
