HasMultipleValues: Boolean;
The HasMultipleValues property determines whether an element may have multiple values by this attribute. True - elements may have multiple values.
The attribute can support multiple values if its type is Link to the Dictionary (see MetaAttributeKind).
Executing the example requires that the repository contains a time series database with the OBJ_FC identifier and an MDM repository with the RDS_REPO identifier. The MDM repository must contain a dictionary with the DICT_COUNTRY identifier.
Sub UserProc;
Var
MB: IMetabase;
Rubr: IRubricator;
Facts: IMetabaseObject;
Att: IMetaAttribute;
CollectionAtt: IMetaAttributes;
Begin
MB := MetabaseClass.Active;
Rubr := MB.ItemById("OBJ_FC").Bind As IRubricator;
Facts := (Rubr.Facts As IMetabaseObject).Edit;
Att := (Facts As IMetaDictionary).Attributes.Add;
Att.DataType := DbDataType.Integer;
Att.Id := "A_M_REF";
Att.Name := New attribute;
Att.Kind := (MetaAttributeKind.Collection) Or (MetaAttributeKind.Dimension);
Att.ValuesObject := MB.ItemByIdNamespace("DICT_COUNTRY", Mb.ItemById("RDS_REPO").Key);
Att.DataType := DbDataType.Integer;
Att.HasMultipleValues := True;
CollectionAtt := Att.CollectionAttributes;
CollectionAtt.BuildCollectionAttributes;
CollectionAtt.CreateTable(True);
Facts.Save;
End Sub UserProc;
After executing the example, the New Attribute attribute is added to the dictionary that contains information about indicators of the time series database with the OBJ_FC identifier. This attribute is a link to the dictionary and supports multiple values. A system table is also created to store multiple values.
