The Factor 2 entry of an SUBDUR operation is not a valid numeric duration.
30
Cause . . . . . : The SUBDUR operation has two forms:
When a numeric duration is to be subtracted from a Date, Time, or Timestamp field then the Factor 2 entry (positions 36 - 49) must contain two parts separated by a colon. The first part must be a variable, literal, or constant which is numeric with zero (0) decimal positions. The second part must be a duration which is compatible with the data type of the result field (positions 50 - 63). The specification is ignored.
Recovery . . . : Correct the Factor 2 entry. Compile again.
