[HelpSeeker]

HI Experts,

I do have a Scenario RFC to REST , when data is been pushed from SAP to PO System , i am facing error in PO monitoring 

Error :  Details: com.sap.aii.utilxi.misc.api.BaseRuntimeException; Character reference "&#, BaseRuntimeException: Character reference "&#, BaseRuntimeException: Character reference "&#, org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 201; Character reference "&#

However this the data that sent from SAP for these fields

    "remark": "Tested from Postman",

    "rejectReason": "Not rejected Test Postman"

NOTE : Total we have 8 fields, data is in payload is displaying as expected .Only for the above mentioned fields , payload is showing as

<REJECTREASON>N&#00;o&#00;t&#00; &#00;r&#00;e&#00;j&#00;e&#00;c&#00;t&#00;e&#00;d&#00; &#00;T&#00;e&#00;s&#00;t&#00; &#00;P&#00;o&#00;s&#00;t&#00;m&#00;a&#00;n</REJECTREASON>
