How to find parameter values in the PDF_REPORT_CREATED event?

Hi All,

I am trying to activate an event action that send the report “Payment Advice” to an email address. But I am having a hard time getting it to work.

All the parameters starting with pdf_ are blank except PDF_PARAMETER_1 and PDF_PARAMETER_2  

I believe PDF_PARAMETER_1 is value in AP Supplier Contact and PDF_PARAMETER_2 is Report ID in Report Definition.

I have been gone through the table in the below link but it doesn’t include how values are fetched for Payment Advice 

https://docs.ifs.com/ifsclouddocs/22r2/default.htm?openpage=https://docs.ifs.com/ifsclouddocs/22r2/Procurement/AboutEmailReports.htm

Can someone help me out find out how the rest of values are fetched? Additionally I have tried to set value for default PDF_PARAMETER_3 using function Pdf_Report_Event_Param_API.New_Parameter after referring ifs community link but still value for PDF_PARAMETER_3 is still empty.
