Batch operation in SAP Odata gives a syntax error

HI All,

I'm trying to do a batch operation on an Odata set but it gives me a malformed syntax error when i execute the URI in Gateway client.

Please find attached along the screenshot of the same. At the same time when i use "boundary=batch_005056A5-09B1-1ED1-BF82-409B26A80600"he header it gives me a success message but does not give me an entity value. Attached also the screen shot of the same.

Appreciate your help.

Thanks,

Praveen
