Hi Hari,
The "PurchaseOrderId" cannot be fetched as attribute in CE_COLUMN_TABLE("SAP_HANA_EPM_DEMO"."sap.hana.democontent.epm.data::purchaseOrderItem",
["PurchaseOrderItem", "Currency", "GrossAmount","ProductId","Quantity","QuantityUnit"]);
So ce_join cannot exec base on "PurchaseOrderId" as join condition.
