Reinstatements not processed in SLA for tax books after partial retirement

Multi-unit asset was retired through sale.  Purchaser decided not to accept the bulk of the units.  The asset was reinstated (returning all units to the active Assets inventory), and then the number of units actually sold was retired, generating a partial retirement.  At month-end close, Create Accounting correctly accounted for and processed both the reinstatement and the partial retirement for the Corporate book.  In our two tax books, Create Accounting processed the partial retirement correctly, but the reinstatement was left in "unprocessed" status.

This is the first time we have had the "reinstate and partially retire" scenario in R12.3.  I'm not sure if this is a tax-book issue, an SLA issue with any (e.g., single-unit) retirement, or an SLA issue with full reinstatement and partiala retirement.
