XML publisher don't recognize Summary columns and parameters

 hello all ,

i have developed a custom report by report builder which is RDF file  with format XML type

The RDF contains the following :

 a.  Summary columns per group and Summary columns per report 

 b.  parameters passed from the form

 c.  formulas columns inside it SRW. built_in gets the report name

then i designed the RTF after that upload it to the EBS xml publisher 

the issue i have now when i run the report

i have found null values in the mentioned above columns

is there is problem with xml publisher that it does not recognize these summary and formulas
