Invokes the EDMmodelChecker to validate a data model against a specified global rule in a remote EDMdatabase. The global rule must be defined within the dictionary model of the data model to validate. It may be defined in the data models underlying Express Schema or in any EDMruleSchema that has been compiled to extend the data models dictionary model.
The expressions logging can be used to trace the execution of the global rule in the EDMexpressVM. The EDMsupervisor and the interactive EDMdebugger may be used for testing and debugging global rules as well as for getting detailed information from the validation process.

Arguments:

serverContextId

Context identification, from edmiDefineServerContext

remoteRepositoryName

The name of the repository in the remote _EDMdatabase_ that contains the model to be validated. Repository names are case sensitive.

remoteMmodelName

The name of the remote model to be validated. Model names are case sensitive. The combination of the <remoteRepositoryName> and <remoteModelName> arguments uniquely identifies a model in a remote _EDMdatabase{_}.

remoteGlobalRuleName

The remote global rule to validate. Global rule names are case insensitive.

nFileMappings

Currently not used.

fileMapping

Currently not used.

options

Currently not used.

remoteRuleSchemaName

The name of the Rule Schema in which the global rule is defined. Rule Schema names are case insensitive and unique within the scope of an Express Schema.

logDescription

An SdaiLogDescription structure containing the specifications for the logging of the validation process.

numberOfParameters

The number of parameters in the <parameters> argument.

parameters

Buffer of pointers to locally allocated tSdaiSelect structures. Each tSdaiSelect structure defines the type and value of an input parameter to the validation process.

userReturnedValue

Pointer to a locally allocated tSdaiSelect structure that may be used by the global rule to communicate a user defined status with the calling application.

result

An SdaiLogical variable that will receive the result of the global rule validation. The returned logical values means;
sdaiTRUE: No global rules were violated.
sdaiFALSE: One or more global rules were violated
sdaiUNKNOWN: Undetermined status due to unset values or error in operation.

edmiInvocationId

Currently not used.

Returns:
A completion code of datatype EdmiError is the returned function value. The completion code has the following values:
Completion code = 0 : Operation successfully performed.
Completion code != 0: Error in operation. Completion code is an _EDMinterface_ error code. Use edmiGetErrorText to get the error text corresponding to the error code.
