Create Default Dimension using cost centre and it's Derived Dimensions in D365 FSCM X++

 Pass the CostCentre value in the parameter to create the default dimension and fill up other dimension values from cost centre's derived dimensions:

Below is the code, pass the cost Centre value as a parameter.

public static DimensionDefault QTQ_CreateDerivedDimension(String20 _costCentre)

    {

        DimensionAttributeValue dimAttrValue;

        DimensionAttribute      dimAttr;

        str                     dimAttrCCValue;

        DimensionDefault        result;

        boolean                 isDerivedDimension;

                            

        dimAttrCCValue          = _costCentre;

        

        dimAttr                 = DimensionAttribute::findByName("CostCentre");//CustParameters::find().QTQ_DimAttName);

        dimAttrValue            = DimensionAttributeValue::findByDimensionAttributeAndValue(dimAttr, dimAttrCCValue, false, true);

                        

        DimensionAttributeValueDerivedDimensions    derivedDim = DimensionAttributeValueDerivedDimensions::findByDimensionAttributeValue(dimAttrValue.DimensionAttribute, dimAttrValue.RecId);

        DimensionAttributeValueSetStorage           defaultDimStorage = new DimensionAttributeValueSetStorage();

        DimensionHierarchy                          dimHierarchy = DimensionAttributeDerivedDimensions::findDimensionHierarchyForDrivingDimension(DimensionAttribute::find(derivedDim.DimensionAttribute));

        DimensionHierarchyLevel                     dimHierarchyLevel;

        DimensionAttributeDerivedDimensions         derivedDimensions;

        while select RecId, DimensionAttribute from dimHierarchyLevel

                                where dimHierarchyLevel.DimensionHierarchy == dimHierarchy.RecId

                                    join DerivedDimensionFieldNum from derivedDimensions

                                        where derivedDimensions.DimensionHierarchyLevel == dimHierarchyLevel.RecId

        {

            DimensionAttributeValueRecId    davRecId = derivedDim.(derivedDimensions.DerivedDimensionFieldNum);

            DimensionAttributeValue         dav = DimensionAttributeValue::find(davRecId);

            defaultDimStorage.addItemValues(dimHierarchyLevel.DimensionAttribute, dav.RecId, dav.HashKey);

            isDerivedDimension = true;

        }

        // If there is no derived dimension available then at-least create the default dimension with Cost Centre Value only.

        if (!isDerivedDimension)

        {

            defaultDimStorage.addItem(dimAttrValue);

        }

        result = defaultDimStorage.save();

        return result; 

    }
