@Kumar1243  Try using the following spec: [ { "operation": "shift", "spec": { "Product": [ "Product", "to_PlndIndepRqmtItem[0].Product" ], "Plant": [ "Plant", "to_PlndIndepRqmtItem[0].Plant" ], "MRPArea": [ "MRPArea", "to_PlndIndepRqmtItem[0].MRPArea" ], "PlndIndepRqmtType": [ "PlndIndepRqmtType", "to_PlndIndepRqmtItem[0].PlndIndepRqmtType" ], "PlndIndepRqmtVersion": [ "PlndIndepRqmtVersion", "to_PlndIndepRqmtItem[0].PlndIndepRqmtVersion" ], "RequirementPlan": [ "RequirementPlan", "to_PlndIndepRqmtItem[0].RequirementPlan" ], "RequirementSegment": [ "RequirementSegment", "to_PlndIndepRqmtItem[0].RequirementSegment" ], "PlndIndepRqmtPeriod": [ "PlndIndepRqmtPeriod", "to_PlndIndepRqmtItem[0].PlndIndepRqmtPeriod" ], "PlndIndepRqmtIsActive": "PlndIndepRqmtIsActive", "NoWithdrawal": "NoWithdrawal", "DeleteOld": "DeleteOld", "PeriodType": "to_PlndIndepRqmtItem[0].PeriodType", "PlannedQuantity": "to_PlndIndepRqmtItem[0].PlannedQuantity", "UnitOfMeasure": "to_PlndIndepRqmtItem[0].UnitOfMeasure", "ProductionVersion": "to_PlndIndepRqmtItem[0].ProductionVersion" } } ] You can use the JoltTransformRecord  or JoltTransformJson processors.  The JoltTransfromRecord will allow you to define a schema for your multi-record input FlowFiles. The JoltTransformJson processor would require you to split you source FlowFile first so you have one record per FlowFile.  Hope this helps you get closer to success,. Please help our community grow.
