Generation of instructions in the VALIDATION section before the STORE or PLACE instructions, for the properties whose associated entity is updated.
Click below for more information on generating management rules in programs (generation paragraph, and the generation point within the paragraph):
Substitution principles
The management rule text variables $$Id are replaced by the screen field of the property to which the management rule is assigned.
The management rule text variables $LogicalProperty are replaced by the screen field (or by the file field if the screen field does not exist) of the property named LogicalProperty, if the latter belongs to the same entity as the property to which the management rule is assigned.
Important note: The replacement of the $$Id and $LogicalProperty variables with a screen field or a file field obeys different rules according to the variable syntax and the program type.

Example
Transforming a screen field before updating the database.
