Hi,
    iam using SAP BAPI  to create the MBO in the preview it is working fine if i give date input as a value or null.
But in the workflow if i did nt pass the date it is giving me error as value is null or empty

Answer 1

thanks kaushik it helped me what i did was recently we migrated to 2.0.1 in that they are allowing us to manipulate workflowMessageToSend in this way im passing default value if the input value is null.
function customBeforeSubmit(screenKey, actionName, workflowMessageToSend) {
     if (screenKey == "StockPerMaterial" && (actionName == "NEXT"))
        if(document.getElementById("SPM_GRDate").value === "")
          var myNewGRdate = new MessageValue();
          myNewGRdate.setKey("myKey");
          myNewGRdate.setValue("9999-01-01");
          myNewGRdate.setType("DATETIME");
          var mvc = workflowMessageToSend.getValues();
          if( mvc ) {
               mvc.add( "SPM_GRDate", myNewGRdate );
