DataSource: PageName as well as Parameter name
PRPC automatically creates a page called 'DataSource' for the integration layer in the response data transofrm while configuring REST connector via wizard. The DataSource page is used to reference/fetch the property values from the integration layer to the Update Primary page as 'DataSource.response_GET'
In addition to creating the page called 'DataSource'. PRPC also creates the Parameter with data type page? Is there an explanation what PRPC creates the parameter called 'DataSource' for?
Hi Dyan,
Any Service you configure either (SOAP, REST), by default pega creates the DataSource Parameter which contains Object name like below, based on that object we can get the Response data, At Run time Data Source parameter contains "pyDataSource1480572246296" by using this, we can get the resposne which is there in xmlstring attribute like below,
{pyObjName=pyDataSource1480572246296; Operation=; pyRequestHeaders=; pyLocalFile=; pyPageName=D_GetAddressDetails; OperationName=; pyRequestParams=; pyClassName=Org-Div-Data-Address; pySQLOption=false; pyResDataTransform=getAddressDetailsResponse; CityName=XYZ; pyStatusMsg=; xmlString= " Entire Service Response is Here"}
In Pega we have to configure DataSource as a parameter of type Page so that we can map the response data to your clipboard, If we didnt specify DataSource as a parameter, we cant Access the Response Data.
Thanks & Regards,
Praveen
Hello Praveen,
Thank you for your reply: I tested the REST configuration without the datasource parameter that does not return the response in the clipboard or datapage. I also wanted to leverate the information from your first two paragraphs. I have REST service configured and tried to find the details including "pyDataSource1480572246296" but could not locate.
Page-Remove happens for "pyDataSource1480572246296" when datapage is about to finish execution,you can see this tracer.The last part of "pyDataSource1480572246296" 1408572246296 is current time with milliseconds,so we need to write response before page gets removed or else if it is a List type of datapage if response Datatransform is left blank the values can be see directly on the datapage(This i have observed in version Pega7.1.7 ).
How are you configuring your parameters? Are you providing sample response? If so, attach the xml.
Need more details.
Also, you can control the naming, if you want. The "DataSource" name is just a guess by wizard.
