Cannot find parameter field Pm-Command.Name in subreport 12. SAP B1

I created report which has sub report in Crystal Reports 2011 in two different databases, I set Link between main report and its subreport, My report works fine in crystal report design but if I import it in SAP B1 9.2 PL10 I get error message while previewing
Cannot find parameter field Pm-Command.Name in subreport 12.
I tried to do research but there is no answer I got. The parameter which has error is the parameter links subreport and main report.
I tried to change subreport links but error is still same
Below is formula of subreport parameter which causes that error.
{Command.Name} = {?Pm-Command.Name}
Please anyone can help me to solve this issue

Crystal reports Count group by

I am very new to Crystal reports and I am working on fixing an existing report.
I am having an issue with a simple function, I am attempting to count the number of patients for each provider. I am connecting to EPIC Clarity database, if that helps. When I use the following, I am expecting to get a count of the patients (based on the number of PAT_ID, A unique field ) , grouped by the PROV_ID (also a unique field) count({PATIENT.PAT_ID},{CLARITY_SER.PROV_ID})
This results in the error: There must be a group that matches this field.
I am not sure what this error is trying to tell me. I have never used crystal reports before and I am not sure where to begin. any help is appreciated.

Crystal report - Null fields not shown

I have, problem with and empty field as they disappear from reports.
I'm able to see only fields with data in them.
if isnull ({orddet_user.orddetlookup2})
then "No Reason"
else {orddetlookup2.descr}
It returns on report {orddetlookup2.descr} but all blank fields doesn't show up,
Maybe someone has faced this before.
I'm using crystal 2008

Openerp using subreport by Jasper Report

I want to create a sale order report with Jasper Report. So, I took xml of sale_order object by Jasper's data template of openerp and I set depth 3 in that xml file. And then, I created report by using Jasper Report. After that, I added this report by using new Jasper Report of openerp. My report has a dataset in the main report for sale_order_lines. So that, I have an error below:
openerp.netsvc: Report Error Failed to invoke method execute in class com.nantic.jasperreports.JasperServer: Error evaluating expression : Source text : $P{REPORT_DATA_SOURCE}.subDataSource("//sub_report")
How to fix this error? If you don't mind, please explain me step by step.

"The Report is empty" - is bug?

I've created report with 3 parameters in iReport and it's running successfully. The report is execute MS SQL stor proc with 3 parameters:
startdate;
enddate;
dept_nm (department name);
iReport gives good result. As soon as I exported jrxml file to JasperReports Server 4.1 I have message "The report is empty".
In the Repository under JasperReports Server I've created controls for dates parameters and single list values for dept_nm parameter.
Do you know how to debug and trace this message coming from???
Your query is returning no data. The message appears when the report result is null.
The quickest way to debug this in JasperReports Server is to modify the report's behavior when no data is returned. The default behavior is "No Pages". Change it to "All Sections, No Details". That way you'll get at least the report title and summary band.
Display your parameters in the title band to see what their values are. Often they aren't what you expect. For example, your input control is "StartDate", but your parameters is "startdate". So the parameter doesn't get the value you thought it would.
I get this a lot. E.g if you have sub reports only, it thinks the main report is blank. You have to do something silly like insert a dummy SQL into your report such as "select 1" then populate a hidden part of the report with the result. When it works on in report studio, but gives you the report is empty on the server (with a good data source - other reports working) is when you have real trouble. Not solved those yet.
Maybe you did not connect your report to any Data Source.
