Attachment Viewer in HWC for viewing photo from Archive

Hi,

I'm using attachment viewer to get images from SAP R/3 Archive and show it on the device.

After going through few posts in SCN. I've created an RFC to export base64 xstring type data, MIME type, size, file name and employee number.

Then I created a MBO with object query to have employee number as parameter.

While using this MBO in a HWC attachment viewer I'm getting "Download attachment gets empty response" as alert message.

In the logs it is having NullPointerException. I've attached screen caps of attachment viewer properties.

Please let me know your valuable suggestions.

Thanks in advance,

Vinoth Kumar
