Direct ship lines periodically creating with OD 00000000 when processing from EDI

I'm on JDE 9.0 UPdate 2 with tools release 9.1.3.4.  We have some customers that we process orders for using F47011 and F47012.  Every so often we get a direct ship item as part of the order and it fails to create a purchase order.  The F4211 record shows OD 00000000.  I have some old notes from back when we were on XE and had the same periodic issue.  The notes state that if a bad record (don't know what is meant by bad) remains in F4301Z or F4311Z, any orders processed after the bad record will not get assigned
