Problem with variables in formulas when using CrystalReportViewer

Post Author: Aksu
CA Forum: Formula
Hi! I have a problem with variables in Crystal Reports formulas, when using CrystalDecisions.Windows.Forms.CrystalReportViewer class from VS2005-project. ReportViewer always gives error:*************Crystal Report Windows Forms ViewerThis field name is not known.Details: errorKindError in File C:\{dir]}\{file}.rpt:Error in formula <mCustomerAttributes>.'Dim result As String'This field name is not known.Details: errorKind ************* Report without variables works fine with Viewer and in Crystal Reports Designer report with variables works also fine. I have tried with both "formula-syntaxes" - basic and crystal. But Viewer always gives error when trying to define new variable.I think the problem might be with CR -versions, because VS-project has formerly been designed to VS2003 and CR9 or 10. Now I'm using VS2005 and CR11. Though I have changed all references to new CrystalDecisions-asseblies (Ver.11.0.3300.0), when I debug the project and checkout the Viewers ReportSources FormatEngine Shows version CR9_2.... I have no idea where it gets this version...***************DEBUG-view when Viewer is created *******************CrystalReportViewer |_ ReportSourceClassFactoryName ... , Version=11.0.3300.0 , ... |_ ReportSource |_ FormatEngine {CrystalDecisions.CrystalReports.Engine.FormatEngine} |_ ClientVersionHeader {CrystalDecisions.Shared.ReportServiceVersionHeader} |_ | version = 920 (int) |_ Static members |_ VER_CR9 = 920 (int)**************************************** Could anyone have any answers or tips for this problem? I'd really appreciate it... ---Aksu

Has anyone been able to answer this question?
I am having the same problem:
I am designing a report in Crystal Reports XI Developer that contains parameters, which are passed to a stored procedure and are also used within formulas ( in Crystal Syntax ie. {?FORMAT_ID} ) in the report itself.
I can run the report successfully in CRXI Developer. The formulas use the correct values from the parameters entered during execution and everything looks good.
I then deploy the report to Business Objects Enterprise XI. I do all of the things necessary to manage the report including setting up the proper database connection information and default parameter values.
When I run the report using the Crystal Report Viewer, I get the following error message:
Error in File Forecasting.rpt:
Error in formula <Report Format>.
'if (not isNull({?FORMAT_ID} ) ) then
This field name is not known.
Details: errorKind
This happens when I press the "Preview" button in the Manage Object dialog from Crystal or when I run the report using InfoView.
I have changed the formulas and it doesn't seem to matter what the specific content of the formula is; other than the existence of a parameter reference in the formula. If I comment out the parameter and replace it with a hard-coded value, it gets through the formula fine.
Does Business Objects Enterprise XI support crystal reports with parameter references in the formulas?
Thanks,
Tim H.

Problem with variable

Hi. I'm making a form for work for people to book places on
training courses. Having an annoying problem with variables that
i'm hoping has a simple solution. Any help with this will be much
appreciated.
All the info is held in an external text file which looks
like this (but much longer):
&totalcourses=2&
&course0=Please choose a course&
&course1=my course one&
&totaldates1=3&
&c1date0=Select a date...&
&c1date1=15 September 2006&
&c1time1=Time: 10:00 to 16:00&
&c1date2=23 January 2006&
&c1time2=Time: 11:00 to 16:00&
&c1date3=28 February 2007&
&c1time3=Time: 12:00 to 16:00&
&course2=my course 2&
&totaldates2=3&
&c2date0=Select a date...&
&c2date1=15 September 2006&
&c2time1=Time: 11:00 to 16:00&
&c2date2=08 January 2007&
&c2time2=Time: 9:00 to 16:00 &
&c2date3=15 February 2007
&c2time3=Time: 12:00 to 16:00&
The course titles are loaded into an array and then into a
combobox. When a course is chosen a second combobox loads the
relevant dates array for that course. When a date is chosen the
time is shown in a dynamic text box.
Problem is - if more than one course is on the same date it
will show the time for the latest course with that date. For
example - course 1 is on 15 sept at time 10:00 to 16:00, course 2
is also on 15 sept at time 11:00 to 16:00. When 15 Sept is chosen
for course one it displays the time for course 2 on this date -
presumably because it comes later in the text file.
I've attached the actionscript for this - Can anyone help me
sort this out??

Problem with Variable Client Support

Hello,
I work with Labview 8.5 and Crio 9014.
I have a problem with Variable Client Support. When I try to compile my project I have the following error:
"The Network Variable Engine and Variable Client Support must be installed on the RT target for this application to function properly..."
I have read that we have to install the Variable Client Support in Measurement and Automation by right-clicking on the software and then choosing add/remove software but I can't install the appropriate shared variable components because I can't see neither Network Variable Engine and Variable Client Support. So what can I do?
Can somebody help me?
Thanks

I have exactly the same problem. I wanted go through the "Getting Started with the LabVIEW RT module" and when I use wizard for generating new project I get same notification in my VI...
The Network Variable Engine and Variable Client Support must be installed on the RT target
for this application to function properly. If the Network Variable Engine is not supported on
the target (e.g. FP-2000 with <32MB of RAM), open the project and move the variable library
to My Computer in the project. Doing this will deploy the variables to localhost but
will still require that Variable Client Support be installed on the RT target.
Could someone help please ?

Problem with variable in the woorkbook selection screen.

Hi All,
I have Problem with Variable in the selection screen. I have four variable in the report in this sequence
<b>Plant (optional), calendar month (mandatory), material (optional), Customer (mandatory). </b>
In Development system, I changed the query to fix the problem for a formula. saved and executed the query. In the selection screen appeared four variables and executed. after executing the query and I saved the work book also. I logged out of the Bex Analyzer. In the RSRT I generated the report by clicking the Generated Report push button. and again logged into the Bex analyzer and ran the work book, now in the selection screen, appeared three Variables only, I am missing the variable <b>Customer</b>.
The old report which is already in the Production system is working fine. What could be the mistake I did in the development system.
It is very urgent, I need to deliver this object as soon as possible.
Can I anybody help on the same.
Thanks in advance
Narendra

Yunus,
I did what you said. I removed the variable from characteristic restrictions, saved the query and executed the query, appeared three variables Plant, Calender month and material. executed and saved the work book. disconeted from Bex analyzer, in RSRT Generated Report and logged into Bex analyzer ran the work book for selection Plant, calender month and material and went into change query definition and added the variable for customer which was removed earlier and and ran the query for selections Plant, Calender monmth, Material and customer. saved the work book. disconnected from Bex analyzer and closed all excel sheets and work books. In RSRT Generated Report and again connected to Bex analyzer and ran the work book, now appeared only three variables again missed variable customer.
Yunus does any missed n the procedure what i did.
It is helped what Chris was answered.
Many Many Thaks for your time and replies.

But there is problem with variables in Title. Replacement of variables STOP working :-( At the page is displayed for example: "@{biServer.variables['MaxDate']}". Variable replacemen works fine in narrative views.
Do you have some ideas?
Thanks.

We have the same problem with presentation variables in titles using externalize strings option, they stopped working after tranlation.

Any ideas?

Problem with variable offset for 0CALMONTH

Hello Community,
I have a problem with using variables offset for time characteristic 0CALMONTH
Let's say my current query looks like this:
...................01.2006..........02.2006..........03.2006   (0CALMONTH)
Sales ..............100..................125................200   (Keyfigure)
What I want do now is to add a previous year comparison. So that it should look this way:
...................01.2006..........02.2006..........03.2006   (0CALMONTH)
Sales ..............100..................125................200   (selected months)
LY_Sales...........50..................100................100   (selected months - 12)
(LY_Sales should show figures of 01.2005, 02.2005 and 03.2006 in this example)
I used new selection for LY_Sales with variable offset for 0CALMONTH -12 but that didn't work. Figures in second line are zero. The desired figures would show up (if I expand the selected time intervall wide enough) in 01.2005, 02.2005 and 03.2005 but that's of course not what I want.
Please help if you can!
Regards,
Ulrich

Hi,
We can get an an other way by using CELL editor caoncept.
First create teh query like this:
...................01.2006..........02.2006........12.2006.....01.2005...02.20005...12.2005 Sales ..............100................125..............200.............50...........100.........100
Sales ..............100................125..............200.............50...........100.........100
Then hide the 2005 years' kf:
...................01.2006..........02.2006........12.2006
Sales ..............100................125..............200
Sales ..............100................125..............200
Though the call editor concept overwrite the second rows(selection) content with hidden columns of second row(selection) one by one .i.e first cell of 2nd row will be overwritten by 13 th cell of second column.similarly second cell of 2nd row will be overwritten by 14 th cell of second column........
First row(selection) : Cal year Charactertic with restriction 2006.
second row(selection) : Cal year Charactertic with restriction 2005.

Problem with variable name in ZXRSRTOP include (virtual KF)

Hi all,
I am coding a routine to use a virtual key figure in the BEx.
I have just a little problem with the name of a variable:
as explained in the documentation, I created the variable with the prefix G_POS_, the name of the infocube and the name of the infoobject all together:
DATA: G_POS_BC_ST_003_C_DIV__C_COMPAR type i.
The problem is that this variable name is longer than 30 characters, so the system doesn't accept it.
Is there a workaround, other than changing the name of the infoobject (which is a navigational attribute)?
Any help would be appreciated.
Loï

Hello Marc,
I understand that I have to use a concatenate function and a dynamic call of the variable with (variable) instruction, but i do not understand how to implement it.
the infocube name is BC_ST_003
the characterisdtic name is C_DIV__COMPAR
So, in the include ZXRSRTOP the statement
DATA : G_POS_BC_ST_003_C_DIV__COMPAR
does not work due a length problem (see first post)
But in the same include the statement
+DATA: l_global_name type c.
concatenate 'GPOS' 'BC_ST_003' 'C_DIV__C_COMPAR' into l_global_name separated by '_'.+
drives to the following error : statement is not accessible.
Could u please provide me with an example of the code in the include ZXRSRTOP, and in the include ZXRSRZZZ for the use of this variable.
Thanks in advance.

Problem with Variable Entry Screen

Hello All,
We upgraded our development systems to NW2004s and came across the following issue:
All our Bex queries have restricted time characteristics with variables entries. When we execute a query it should pop-up the variable selection screen for us to enter the restriction values but the query is ignoring Variable restriction screen and taking into consideration everything. The same query works fine in Prod., which is still in 3.1.
Did anyone come across this situation kind of situation? It did not pop-up any type of error and we are in SPS10

Problem with Variable 0I_CUFQU

Hi all,
We are using Fiscal year/ Period with variable SAP Exit 0I_CUFQU in FIGL_V11 reports.
Earlier It was working fine but after Patch Upgrade when I run the same report I am getting the Follwing error.
Variable 0I_CUFQU could not be replaced.
If anyone knows the answer please share the solution for the same.
Regards,
Ali.

Hi Ali,
All these variables use sap exit varaible 0P_FVAEX for thier internal calculation. this is a program error and cen be resolved by SAP note 1322757.
The following SAP exit variables for BW queries may be affected by the error (the technical names for the variables):
0P_PRFP1, 0P_PRFP2, 0I_CUFYE, 0I_PRFYE, 0I_CUFQU, 0I_PRFQU,
0I_PRFY2, 0F_CUFPE, 0F_FPER, 0I_P2FQ0, 0I_P3FQU
This note will correct the program error.
Let me know if this works.
Thanks,
Amit

Problem with variables in dynamic SQL/PLSQL

Hi, I have a problem I am trying to solve using a very short piece of dynamic SQL/PLSQL but I am having problems getting the variable values out of the dynamic block.
I need to increment a counter which could be any one of 16 counters I am using and I want to avoid using nested IF statements.
The variable to be incremented is made up of the 'scheme', the 'contributory category' and the 'employment category' (although not every combination is valid)
The 'scheme' can be either 'no1', 'no2', 'off', 'cg' or 'amc'
The 'contributory category' can be either 'cont' or 'noncont'
The 'employment category' can be either 'ft' or 'pt'
For example the total variable name could be 'v_cg_noncont_ft_count'
I have created a variable by concatenating the various elements called v_incr_count_name which holds the name of the variable I want to increment.
I am running this within an anonymous PLSQL block so I cannot use global variables meaning that my variables are not visible within a dynamic PLSQL block.
As a result I think I will need to use bind variables with a PLSQL block or a SELECT FROM INTO SQL string
I have tried various solutions including the following PLSQL solution:
v_incr_count_name := 'v_'||v_scheme||'_'||v_cont_cat||'_'||v_emp_cat||'_count';
sql_stmt := 'BEGIN :a := :a + 1; END;';
EXECUTE IMMEDIATE sql_stmt USING v_incr_count_name;
Unfortunately I am getting the 'IN bind variable bound to an OUT position' error which I suppose makes sense as I am trying to change the value of a variable in the main PLSQL block from within the dynamic block.
Another (SQL) solution I tried was:
v_incr_count_name := 'v_'||v_scheme||'_'||v_cont_cat||'_'||v_emp_cat||'_count';
sql_stmt := 'SELECT '||v_incr_count_name||' + 1 FROM DUAL';
EXECUTE IMMEDIATE sql_stmt INTO v_return;
While this executes and returns the incremented value into v_return, I am still left unable to copy the returned value into the variable whose name is stored in v_incr_count_name
Any help appreciated
Cheers, Dan

this shows the syntax for the using clause
declare
a number := 1;
b number := null;
v varchar2(10) := 'A';
begin
execute immediate 'begin :v1 := :v1 + 1; end;' using in out a;
dbms_output.put_line(a);
end;
/but what you want cannot be done
SQL> declare
