R12.2.3 Payables: Maximum value size is violated for DFF

The issue described in MOS article "DFF Error - The Maximum Value Size For Segment Is X. Truncating Value To Xxx (R12.2)" from document ID 1960243.1 may be due to a direct upgrade from 11.5.10.2 right to 12.2.3 but I will bet it could also be seen if you upgrade from an earlier version of R12 as well!  Check out the associated bug and patch for all the details and update your testing suites accordingly!
