I am facing an issue with DHIS 2.17, The parameter "reporting_month" is not recognized in DHIS2.17 where as it works well in DHIS2.15

I am facing an issue with DHIS 2.17. Initially I designed several reports under DHIS 2.15, later on for extending the pivot features I migrated it to DHIS 2.17.

Currently the report templates are displaying blank records in DHIS 2.17, when we analyzed the Jasper (.jrxml) template I noticed the following issue.

In DHIS 2.15 we used the following field declaration under the jrxml to fetch the report data dynamically and it works well.

in 2.17 the same declaration along with the same template is generating blank records (or) no value.

However, when we tried the same template with a hard coded value as given below it works fine in DHIS 2.17

From the above , I inferred in DHIS 2.17 the value "reporting_month" is not passed correctly at run time. Please let us know, on how exactly to pass the parameter "reporting_month" in DHIS 2.17.

We have also carried out several data entry and indicator creations in the migrated DHIS 2.17 dump. Currently we are not able to revert back to the older version.

Reverting the changes to older version involves lot of manual effort which is not possible at this point of time.

Please suggest.
