ModificationRule (Property) In french: RègleModification
The ModificationRule property is used to configure the modification rule (integrity management) to be applied to the data file described in the code. You can: - Find out the modification rule used for a data file defined in the analysis or by programming.
- Define the modification rule used for a data file (when the link is described by programming).
// Define the modification rule used in the OrdLine link
OrdLine.ModificationRule = hIntegrityForbidden
...
// Validate the data file description
HDescribeFile(OrdLine)
Syntax
