PO in Follow-on Documents shows as Archived

Hi All

We are using SRM 5.50, Extended PO. We have few POs which in Ordered status in SRM portal however the POs actually not sent over to ECC. I've tried to manually trigger the PO using FM BBP_PD_PO_TRANSFER_EXEC_V2/ BBP_PD_PO_TRANSFER_EXEC but it doesnt get updated in ECC. We keep on recieving pop up message 'Error while reading PO in backend. Inform system administration', BBP_CF010. And I noticed that in SRM portal, in Follow-on Documents in Item Data tab, the PO status shows as Archived instead of Ordered as in portal initial screen and in BBP_PD. And there's no error seen in BBP_PD. I'm suspecting the error message generated due to the Archived status.

Please advice. Thanks
