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.
