Unable to update PO lines having multiple schedule lines

Hi team,

We are trying to update ship to location on PO lines using 'fscmService/PurchaseOrderServiceV2' SOAP service. It is working when we have single schedule line for PO but if we have multiple schedule lines it is giving below below error.

PO:::PO_CO_NO_UPDSCHED_BUYER JBO-PO:::PO_CO_NO_UPDSCHED_BUYER: PO-2055449You can't update the DestinationTypeCode attribute on a purchase order schedule that has a backing requisition line managed by an external application.

Thanks,

Praneeth.
