When datetime property value is empty it displays the default date.

Can you create Dynamic System Setting(DSS) with below value and observe the behavior.

Purpose: disableEpochDateTime

Owning ruleset:Pega-IntegrationEngine

Value: true/false

Our environment have this DSS disableEpochDateTime with "true" value . After change value to "false" this problem don't reproduce, but appear other problems. Therefore, the value returned to "true". Is there have any other options to fix this behavior? 

May I know the version of PRPC you are in?

There is existing Hfix for PRPC7.1.7.

Gangababu Gollapalli, Pega 7.1.8

I tried in 7.1.8 local environment, it seems to be working when we set the DSS to true.

< xsi:type="xsd:anyType" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <name></name> <origin></origin> <Joindate></Joindate> <Enddate></Enddate> </>

Without DSS:

< xsi:type="xsd:anyType" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <name></name> <origin></origin> <Joindate>1970-01-01T00:00:00.000Z</Joindate> <Enddate></Enddate> </>

Can you run the XML Stream rule standalone with or without DSS?

Gangababu Gollapalli, yes. Without DSS i get

• <Joindate>1970-01-01T00:00:00.000Z</Joindate>

But if i delete dss (or set false value), then i get other problems. On our environment this DSS have true value knowingly.

Could you please provide the output with DSS set to true? Are you seeing empty date value or any other value?

<Joindate></Joindate>

Look at BirthDate

                    <ns2:ClientInformation>
                        <ns2:ClientJurisdiction>CJ_000001</ns2:ClientJurisdiction>
                        <ns2:ClientStatus>Not found</ns2:ClientStatus>
                        <ns2:ClientName>Иванов_4 Иван Иванович</ns2:ClientName>
                        <ns2:ProductName>Корпоративное кредитование</ns2:ProductName>
                        <ns2:ProductType>4</ns2:ProductType>
                        <ns2:CreditType>1</ns2:CreditType>
                        <ns2:CreditPeriod>12</ns2:CreditPeriod>
                        <ns2:PartyType>6</ns2:PartyType>
                        <ns2:BirthDate/>
                        <ns2:IDlink>0-3FTZ9</ns2:IDlink>
                    </ns2:ClientInformation>

Set DSS Entry - StreamXML/DetectEmptyProperties to true as shown below:
    DSS Entry - StreamXML/DetectEmptyProperties
    Owning Ruleset - Pega-IntegrationEngine
    Value - true
    Re-save all the XML Stram rules used within the flow having the problem.

Please run the scenario with above DSS set.
