IRdsCompoundDictionarySource.Mappings

Syntax

Mappings(Attribute: IRdsAttribute): IRdsAttribute;

Parameters

Attribute - custom attribute of a composite dictionary, for which it is necessary to set binding.

Description

The Mappings property determines binding of an attribute of a composite dictionary to an attribute of source dictionary.

Example

Executing the example requires the MDM repository NSI_1. This repository contains two dictionaries: 1) a standard dictionary with the Dict_1 identifier; 2) a composite MDM dictionary with the CompDict_1 identifier. Each dictionary contains an additional attribute with the ATTRIBUTE identifier.

Sub Main;

Var

MB: IMetabase;

MObj: IMetabaseObject;

Dict: IRdsDictionary;

CompDict: IRdsCompoundDictionary;

CompSources: IRdsCompoundDictionarySources;

CompSource: IRdsCompoundDictionarySource;

Begin

MB := MetabaseClass.Active;

MObj := MB.ItemByIdNamespace("CompDict_1", MB.ItemById("NSI_1").Key).Edit;

Dict := MB.ItemByIdNamespace("Dict_1", MB.ItemById("NSI_1").Key).Bind As IRdsDictionary;

CompDict := MObj As IRdsCompoundDictionary;

CompSources := CompDict.Sources;

CompSource := CompSources.Add;

CompSource.Id := "New_Source";

CompSource.Name := New source dictionary;

CompSource.Source := Dict;

CompSource.Mappings(CompDict.Attributes.FindById("ATTRIBUTE")) := Dict.Attributes.FindById("ATTRIBUTE");

MObj.Save;

End Sub Main;

After executing the example a new source is added into a composite dictionary. The MDM dictionary Dict_1 is data source. An additional attribute of a composite dictionary is linked to the similar attribute in the MDM dictionary.
