Payroll Data Migratn: extracting data for T558A-BETPE

Folks,

We have a custom program to read data from the text file and upload to T558A. (the structure of the upload file has all the fields of T558A)

My legacy also uses SAP and hence i am trying  to extract from the standard Wage type reporter (H99CWTR0), but could not retrieve the rate field (BETPE). Is there any standard report that pulls data for T558A / we need to write custom program to download all the fields ?

Thanks!
