Update only cost center from given ledger dimension using X++ in D365 F&O

This code snippet allows you to change certain dimension values as needed and provides you with the updated ledger dimension.

MainAccount mainAccount= LedgerDimensionFacade::getMainAccountFromLedgerDimension(_accountingDistribution.LedgerDimension);

                    DimensionDefault defaultDimension = LedgerDimensionFacade::getDefaultDimensionFromLedgerDimension(_accountingDistribution.LedgerDimension);

                    defaultDimension = this.mergeCostCenterWithDefaultDimension(defaultDimension, inventSite.CostCenter);

                    LedgerDimensionAccount ledgerDimensionAccount2 = LedgerDefaultAccountHelper::getDefaultAccountFromMainAccountRecId(mainAccount.RecId);

                    _accountingDistribution.LedgerDimension = LedgerDimensionFacade::ServiceCreateLedgerDimension(ledgerDimensionAccount2, defaultDimension);

public DimensionDefault MergeCostCenterWithDefaultDimension(DimensionDefault _defaultDimension, DimensionValue _costCenter)

    {

        DimensionAttribute                          dimAttribute;

        DimensionAttributeValue                     dimAttributeValue;

        DimensionAttributeValueSetStorage           dimStorage = new DimensionAttributeValueSetStorage();

        const str                                   costCenter = '@JP:Costcenter';

        DimensionDefault                            defaulDimension;

        if (_costCenter)

        {

            dimStorage          = DimensionAttributeValueSetStorage::find(_defaultDimension);

            dimAttribute        = DimensionAttribute::findByName(costCenter);

            dimAttributeValue   = DimensionAttributeValue::findByDimensionAttributeAndValue(dimAttribute, _costCenter, true, true);

            dimStorage.addItem(dimAttributeValue);

            defaulDimension = dimStorage.save();

        }

        return defaulDimension;

    }
