title: Optional Input Values in SUP Personalization Parameters(iOS)
body: <p>I am creating an iPhone application with SUP. I am using SAP as my datasource.In my MBO s I created some personalization parameters not any synchronization parameters.Some of them are optional inputs.For eg I have an MBO for approving purchase orders.I can approve them with or without comments.Here comment field personalization parameter is a Nullable (optional)parameter and PO_Num  parameter is not NUllable.My problem is when I approve a purchase order with comment my comment field is not inputted to the server.But approval is doing fine.I have this problem in other MBO s also.I am sure that I am setting the comment personalization parameter from my application.This issue is happening only in iOS.Because my android colleague using same MBO s in android.He had not such issues.I am using SUP 2.1.3.</p>
  
  <p>I am new to SUP
  Any help is appreciable
  Thanks</p>
