Hello Experts,

I am using Item Publication event to get data in OIC from PDH. We get a zip file with xml file for Item like ITEM_0.xml .

In Item payload, which fields can provide me information whether it is created item or updated item.

Note - In received data, CreationDateTime and LastUpdateDateTime have difference of seconds.

<ns5:CreationDateTime>2018-07-25T12:10:21.44Z</ns5:CreationDateTime>
 <ns5:LastUpdateDateTime>2018-07-25T12:10:26.189Z</ns5:LastUpdateDateTime>

Thanks,

Kunal
