EdmiError edmiRemoteDeleteGroupBN(SdaiServerContext serverContextId,
                                    SdaiString        groupName, 
                                    SdaiInvocationId  *edmiInvocationId);

Deletes an EDMgroup identified by its name from a remote EDMdatabase. An EDMgroup may not be deleted as long as an EDMuser is connected to the remote EDMserver with this EDMgroup account. Neither may an EDMgroup be deleted if any data in the database have the actual EDMgroup to be deleted as the owner group. Only the superuser may use this function.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiString	groupName	The name of the EDMgroup to be deleted.
SdaiInvocationId	edmiInvocationId	Currently not used.

Return Value
