Invalid ID for order processing

What causes this issue?

INCLUDE BDEOIO_ID_ERROR OBJECT DOKU ID TX

System Response

It is not possible to process the IDoc.

How to fix this error?

It is possible to change the <ZK>ARCKEY</> field of the control record
to process the IDoc despite errors with the ID:
If the content of the field is deleted, the IDoc is transferred to the
application (no sequential processing).
If a valid ID is entered in the field, the application is called,
depending on the sequence information that is entered.
Note that changing the field content can affect the processing of the
IDoc if sequence dependencies to the current IDoc exist.
