Specifies prerequisite conditions for rule activation. The rule is activated only if the specified prerequisite conditions exist.
Figure 188 IN Parameter Format
Optional. A prerequisite condition is a descriptive name of from 1 through 20 characters. A date reference is associated with each condition.
Prefixing a prerequisite condition with the NOT symbol (the Ø or ! character) indicates that the activation of the rule is dependent on the inverse of the condition, that is, the nonexistence of the prerequisite condition.
Prefixing prerequisite conditions with the OR symbol ("|") indicates that only one of those "OR" conditions (and all "non-OR" conditions) must exist to trigger the rule.
Note: A condition name should not begin with the "|" character, since this character is used in defining Boolean logic. It should also not begin with the Ø or ! character, since these characters are used in specifying inverse conditions.
The date reference for each IN condition is four characters long and is optional. It can be a specific date, in either mmdd or ddmm format, depending on the site standard, or it can have one of the values shown in Table 151.

Value |
Description |
|---|---|
ODAT |
Original schedule date (the default). |
PREV |
Rule’s previous schedule date (or, for a forced rule, ODAT-1). |
STAT |
Indicates that the condition (for example, IMS_ACTIVE) is not one that is date-dependent. |
Note: Before STAT was introduced, date 0101 was recommended to be used in conditions that were not date-dependent. Unlike 0101, STAT is not a date, and it operates differently. Always use STAT when defining conditions that are not date-dependent. |

**** |
Any schedule date. |
