the error message: SE 337 Please enter a line number.

Dear Experts,

We have a PO that can not be transferred to P1 because of the error message:

SE 337 Please enter a line number.

We tried to checked the transfer of the PO.

The error message came from the Backend Function BBP_PO_INBOUND.

But it is not possible to define the exact cause of the issue (the exact transfer parameter) due to missing RFC authorization.

The following changes were made in the PO (PO already mapped in Backend) after that PO cannot be transferred:

- a deleted item was set back

- WBS Element was changed

Thank you in advance.

Best regards

Evgeny
