edmiDeleteProtectedElement

EdmiError edmiDeleteProtectedElement(SdaiAggr aggrId,
                                      SdaiPrimitiveType valueType,
                                      ...);

Deletes all elements with a given value from an aggregate in a protected attribute. Some system models are created and maintained by EDM and therefore the users need no write access to them. However, in these system models, some attributes may still be manipulated by selected users even if the model it self is open for read only. The ordinary operations such as e.g sdaiAdd and sdaiDelete, would return an error code if used on these attributes. To manipulate protected attributes one must use the protected-versions of the operations.

Arguments

Type	Name	Comment
SdaiAggr	aggrId	A numeric aggregateID that uniquely identifies the protected aggregate of interest in the EDMdatabase.
SdaiPrimitiveType	valueType	The primitive type of the data value to be deleted from the protected aggregate.
	value	The value to delete from the protected aggregate.

Return Value

Error rendering macro 'excerpt-include' : User 'null' does not have permission to view the page 'US:_r_EDMInterface'.
