The document tested is a part, an assembly or a drawing.

Bracket the operation only if two properties exist in the document.

The statute of the value turned over can be selected ''Equal to'' or ''Different from''. The test can be performed on numeric or alphanumeric values.

For numerical values or date we can choose''Superior or equal to'', ''Superior with'', ''Inferior or equal to'' or ''Lower than''.

Example : If, in the document, the property ''Description'' exists and that its value is different from that of the property ''Designation'' then the operation is applied.
