Weird Target Too Small error

Unusually I can figure out and correct the dreaded target too small error.

But twice in the last two weeks I got this error message in a program that 
has been running just fine for almost a year. My last mod was to put the 
monitor statement in to the code so that in the event the record was 
locked it would drop out of the sr.

The Data12 DS gets its data from a 12 byte data queue. Status field never 
changes. The key is defined as shown below, but the error occurs on the 
SETLL statement. Anyone with any clue as to why a fixed length key, with 
all fields with valid values would generate a target too small error on 
the SETLL statement?
