The crisp argument is used to derive a trueness level from a data link (either simple or calculated) by comparing its expression to the data link's value. It returns true, false, or undetermined.

The crisp argument is composed of any number of operator-operand pairs. The results of each pair are logically “ANDed” together for the final result.

See also the fuzzy argument.


Operands can be either numeric or string (text). NetWeaver makes automatic conversions from one to the other when it is necessary.


The following operators are valid for either numeric or string operands. If the operand and data link value are numeric or convert to valid numeric values then the evaluation is straight forward and proceeds as a numeric comparison. If the operand or data link value do not both convert to valid numeric values then the operation is performed as a string comparison: the comparison is done on their respective alphabetic sort order.

Symbol Description
< less than
<= less than or equals to
= equals
>= greater than or equal to
> greater than
!= not equal to

These operators are valid only for string operands and values. If these operators are used then the operand is first converted to a string.

Symbol Description
is in the operand is a substring of the data link's value
contains the data link's value is a substring of the operand


Operator-operand pair examples where x is the value (either numeric or string) of the data link:

operator operand meaning - “the argument is true if:“
< 3 x is less than 3
< bob x preceeds 'bob' when ordered alphabetically
is in constantinople x is a substring of 'constantinople'
contains ant 'ant' is a substring of x
