A property does not exist
The document tested is a part, an assembly or a drawing.
Bracket the operation if a property does not exist in the document.

You can use the character ''*'' placed in front of or behind a specific character string, in order to test the absence of a property in the document, comprising the character string.

Pro* if a property starting with Pro do not exist in the document, then the operation is applied.
*000 if a property ending in 000 do not exist in the document, then the operation is applied.
You can also define several properties by separating them by the character '';''.
Example :
Code_Article;Treatment; Supplier
If none the properties Code_Article, Treatment and Supplier do not exist in the document, then the operation is applied.
