Does SAP PO support time skew?

[ankit_srivastava3]

Hello Experts,

While using AXIS adapter, WS-Security header can be configured for actions UsernameToken and Timestamp.

Timestamp format is like:

<wsu:Timestamp wsu:Id="TS-889">
     <wsu:Created>2014-06-10T05:38:20.179Z</wsu:Created>
     <wsu:Expires>2014-06-10T06:08:20.179Z</wsu:Expires>

</wsu:Timestamp>

1. I have observed that SOAP requests with "Created" in the future timestamp is accepted as valid request. Why so?
2. In case of any difference between the clocks of "Sender" and SAP PO, time skew (if configured) will take care of the variations in the clock. I believe it should be configured at system level and by system admin. Correct?
3. Is there any document relating to how time skew is supported by SAP PO?

Thanks,

Hi Ankit,

I'd guess this is related to this thread right? Please check the docs on security settings for the sender agreement.

Depending on the technology, you are using the process might be different. For PI it should be setting

Check Time Stamp and specify a validity period as shown on the help page.

Kind regards,

Patrick

Hi Ankit,

sorry, I'm not an expert for the Axis Adapter. However did you check the AXIS FAQ? They have some info on how to do WS-Security with AXIS. This also includes how to use WS Security with AXIS.

Hello Patrick,

Yes, I have already checked AXIS FAQ and it does talk about WS-Security but it does not talk about additional options/features like time skew.

Thanks,
