Smart Part
Enter a formula that calculates the part number associated with a rule. A smart part formula consists of a literal value (constant) and a segment answer (variable). The literal value must be in single quotes. For example:
The part number consists of the literal 'P'
and the value of segment 4.
If the smart part calculation and the value of Segment 4 is 2000, then the smart part
would be P2000.
To reference segments that have already been entered on a different level, specify the item number of that level with the segment number. For example, the notation for Segment 4 of Piston is:
Derived Calculation S4=Piston=
SUBSTR(S4,2,3)
where 2 is the beginning position and 3 is the length of
the substring.
To combine two fields, use the concatenation function. For example,
CONCAT(S3,S1)
which will combine the values of Segment 3 and 1 into
one field.
