We just came across a 1099/Copy B that did not issue.  Everything at the Vendor level looked correct as well as at the voucher level, yet when trying to review the payment in Adjust Withholding, it did not exist.  Nor did it exist on the WTHD_TRXN_TBL after all processing was complete.

The voucher did appear in Withholding Invoice Line Update as checked for Current Withhold yet a Copy B never produced.
