Refund not Creating GL Entries

PeopleSoft Financials - AR 9.2.39

Odd occurrence. A user processed a refund, but no GL entries were generated. Here's our situation.

We have turned off the link between AR and AP, so AR does not send refund information to AP. That happens manually.

We have set up the Automatic Entry type to require a reason code for refunds.

But for this particular refund, the reason code is blank. (I queried the ITEM, ITEM_ACTIVITY and ITEM_DST tables) The refund has processed through the system. The item status is closed. The customer account is correct. But in addition to the ENTRY_REASON being blank, the ARRE_STATUS field is also blank. That is what seems to be preventing the journal generator from picking up the entries.
