Grants individual access rights to a protected instance to an EDMuser or an EDMgroup in a remote EDMdatabase^.The access rights granted by this function will only be effective in cases where the EDMuser/EDMgroup would otherwise be given public access. I.e, owners and administrators can not have their access rights increased or reduced by having individual access rights set for them. Only owners, administrators and superuser may use this function.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiAppInstance	currInst	A numeric instanceID that uniquely identifies a protected instance in the EDMdatabase for which individual access rights are to be granted to an EDMuser or EDMgroup.
SdaiInstance	userORgroupId	A numeric instanceID that uniquely identifies an EDMuser or EDMgroup instance in the EDMdatabase to be granted individual access rights to the protected instance given by argument <currInst>.
SdaiUnsignedInt	accessRights	A bitwise OR of any combination of the symbols below: DELETE_ACCESS EXECUTE_ACCESS CREATE_ACCESS WRITE_ACCESS READ_ACCESS
SdaiInvocationId	edmiInvocationId	Currently not used.
