Make Child business component read only: Parent Read Only Field.
This property, like BC Read Only Field, places a read-only restriction on an entire business component, rather than a single target field. This restriction occurs when a TRUE or FALSE test field has a TRUE value.However, unlike BC Read Only Field and Field Read Only Field, this user property is used to place a restriction on a child or grandchild (and so on) business component of the business component containing the test field. In the other user properties, the read-only restriction is placed on the business component containing the test field, or on another field in the same business component.
Parent Read Only Field is used primarily to restrict the detail records in a multi-value group. It could also be used to restrict the detail records in a master-detail view, but in that case you need to make sure that the restricted business component is not also used in the context of some other business object than the intended one.
The Name and Value properties in the user property record are specified as follows:
Name. Contains the literal text Parent Read-Only Field.
Value. Contains an expression in the following format:
Example: Name. Parent Read Only Field
Value. Account. Competitor Calc
Competitor Calc:-IIf([Type] = "Competitor", "Y", "N")
NOTE: When using the Parent Read Only Field user property, the test field must have its Link Specification property set to TRUE. Otherwise the dynamic read-only functionality does not work. However, if the child record is displayed in the multi-value field in the parent business component, it is not necessary to have the Link Specification property of the field set to TRUE.
