Shorten LOV list in parameter field

Hi,
I have a quesiton regarding LOV. Say, if I define a parameter Employee_Last_Name as search condition for my report. Then I define list of values for Employee_Last_Name. Is there any way user can enter partial string to shorten LOV?
Thanks,
Amanda

Are we talking on different version of Discoverer? I am referring to Discoverer 4i. In both desktop or viewer version of Discoverer 4i, the LOV always show whole list of values even if you enter partial string and wild card. Please let me know if 9i or 10g correct this issue. Thanks.

Forcing a user to only select from Parameter LOV list

Hi,
I suspect that the answer is no but I'd appreciate clarification on the matter. I am wondering if there is any way to prevent a user entering a value into a parameter field - I want them to only select from the parameter's drop down LOV list. This will apply to Discoverer Viewer but would like to know if it could be done for Plus ( or not ) as well,
Kevin.

Hi Kevin
Try changing the item class property called Require user to always search for values.
According to my notes: This is unchecked by default. If you check this, Discoverer will launch the Search dialog box whenever a user clicks on the list of values. Should you have a large list of values, you may want to consider turning on this optionto making the LOV box pop up automatically.
I am not convinced this will make the pop-up come up but it's worth a try.
I'd be interested in hearing how you get on.
Best wishes

How to edit data using a LOV list AND textfield for one Field

I am trying to edit the templated edit from HTMLDB template when I create a new table. I implemented most of the fields with LOV list like yes/no, joe/bob/john etc. But some fields as many probably have seen have a LOV called "Other" where a person types a different value than the ones available. Can someone tell me how I can accomplish that? Do I need to insert "Other" into LOV and have it be set as the value in the textfield? I am not sure how i can create both LOV list and textfield per category/field i.e. Name.
Thanks

Again, I urge you to use HTML DB nomenclature to describe what you've done. For example: "I ran the Form on a Table wizard to create a form" Rather than using the word "template" for everything you describe. "Template" has a specific meaning in HTML DB and it is not what you are referring to.
You really should invest the time required to accurately phrase your problem. Just like answering questions on this forum requires time, so does formulating your question. It is time well spent and it is effort on your part that the experts on this forum deserve. If you don't put in this effort and instead just post a stream of consciousness, that means the readers of this forum will gloss over your question and ignore it. As a result, you have to ask the question again...and again.
Having said that, if I understand your question correctly, you should use a popup LOV item. This will allow the user to select from a list but will also allow typing of a non existent option into a text field.

How to Hide the Parameter field at run time....

Hi,
I have a parameter field which behaves differently depending on the User logged in.
It has the LOV coming from following SQL.
SELECT customer_name FROM Cust_mast;
If the user = 'INTERNAL' then the Where clause will be
WHERE cust_id in('DELL', 'SBC', 'BANK')
Else there will be no WHERE clause or the parameter field
should be hidden in the parameter form.
So my questions are:
1) How to hide the Parameter field during Run time?
OR OR OR
2) How to change the LOV select statement during Run time?
Thanks.
Ram.

Hi Ram,
Is there any way to play with the sql query SELECT using DECODE ?I'm not sure of this part, maybe someone else can suggest a way.
However, what you want can be done in 2 other ways:
1. Build 2 reports. Both reports will just be duplicates of each other, only difference being that the 'LoV where clause' will be different. Now you can fire the appropriate report in many ways. For example, if the customer is alreay logged inside your custom application, and therefore you already know whether the user is internal of external, you can design your button or link which launches the report to contain logic such that one of the 2 reports is fired depending on who the user is.
1. Use a JSP parameter form, not a paper parameter form In this case, just build an HTML parameter form in the web source of your report. Use Java logic to populate the LoV drop-down list. When you have to launch the final report, just launch the paper-layout of the report. For example (you will have to modify this):
<form action="http://machine:port/reports/rwservlet?report=ParamForm.jsp+..." name="First" method="post">
<select name="selected_customer" onChange="First.submit()" >
<option value="">Choose a Customer Name
<rw:foreach id="G_cust_id" src="G_cust_id">
<rw:getValue id="myCustId" src="CUSTOMER_ID"/>
<rw:getValue id="myCustName" src="CUSTOMER_NAME"/>
<option value="<%=myCustId%>"><%=myCustName%>
</rw:foreach>
</select>
</form>
In the code above, you will have to make sure that your report's data model defines 2 CUSTOMER_ID's (like CUSTOMER_ID_INT and CUSTOMER_ID_EXT). These 2 will be internal and external Cust ID's. Use Java logic to show one of them.

Need help with parameter fields and report selection.

Hi all:
I hope some one can help me with the problem I am having with my parameter field and record selection.
First, can anyone explain to me why my parameter field CustStart, which is dynamic and is based on the field Customer in the table CustMaster. There are over 1800 records in the CustMaster table but the drop down list only shows maybe about half of them and there is no way to scroll down to the last customer record. What am I doing wrong?
Second, is there any way to base a parameter field on a formula field on my report? On my report I have created a field Cust that is the customer name and number joined together in one field. I would very much llike to use this formula in my record selection and in my parameter field. Can it be done?
All help is greatly appreciated
Thanks,

Hi,
You can use the following for changin increasing the LOV.
Crystal Reports XI BusinessObjects Enterprise XI
For performance reasons, in Crystal Reports XI Release 1 and Release 2 the maximum number of values that are returned for a list of values is set to 1000. If you have a cascading List of Values (for example Country > Region > City), the lowest level (in this case City) will only display a maximum of 1000 values. This means that the higher-level prompts may display far fewer values than you expect. The list of values provides the data for the dynamic parameter list.
How can you modify the maximum number of values available in a dynamic parameter list?
Resolution
To increase the maximum number of values available in a dynamic parameter list, you must add a registry key.
CAUTION     The following resolution involves editing the registry. Using the Registry Editor incorrectly can cause serious problems that may require you to reinstall the Microsoft Windows operating system. Use the Registry Editor at your own risk. For information on how to edit the registry key, view the 'Changing Keys and Values' online Help topic in the Registry Editor (Regedit.exe).
It is strongly recommended that you make a backup copy of the registry files (System.dat and User.dat on Win9x computers) before you edit the registry.
Crystal Reports XI Release 1
1.     Create a registry key HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV.
NOTE     Alternatively, you can create the registry key HKEY_CURRENT_USER\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV and that key will override the settings of the HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV key.
2.     Add a string value "MaxRowsetRecords" and set the value to the maximum number of values that you desire for your report. For example, a value of 2000 will return up to 2000 values in the lowest level of a cascading parameter. NOTE: The value 0 (Unlimited) will not work with BusinessObjects Enterprise XI or Crystal Reports Server XI, you must specify another value.
NOTE     The higher the number of values is, the longer it will take the Enter Values dialog box to populate with values.
3.      After making changes to the registry, restart the affected service or application as required.
Crystal Reports XI Release 2
1.     Create a registry key HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV.
NOTE     Alternatively, you can create the registry key HKEY_CURRENT_USER\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV and that key will override the settings of the HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV key.
2.     Add a string value "MaxRowsetRecords" and set the value to the maximum number of values that you desire for your report. For example, a value of 2000 will return up to 2000 values in the lowest level of a cascading parameter.
NOTE     The value 0 (Unlimited) will not work with BusinessObjects Enterprise XI or Crystal Reports Server XI, you must specify another value.
3.     After making changes to the registry, restart the affected service or application as required.
I hope this helps you.

Prashant

Null values not displaying in the LOV on the parameter form.

My report works perfect while in Oracle Reports 10g, however when I move it to our menu (Oracle Forms 10g) it does not display the null in the LOV on the parameter form.
This report allows the the user to select by inspector or district or everyone for certain dates.
Ex: I have 4 parameter fields. The user must enter the start & end dates and either the Inspector or the district or leave the inspector or district null to run for everyone.
The district LOV is :
select dnr_section_code, description from dnr_section_code where dnr_section_code in ('29', '38','52')
UNION
select null, 'All' from dual
order by 2 asc ;
The inspector LOV is:
select null , 'All' from dual
UNION
select person_seq, first_name||' '||last_name inspector from vw_eng_inspectors
order by 2 asc
In my Data Model query I use the :
My select
from tables
where clause
+
----by inspector
and (prod_fac_inspections.person_seq_inspector =
nvl(:inspector,prod_fac_inspections.person_seq_inspector))
---by district
and
(d.dnr_section_code = nvl(:district,d.dnr_section_code)
and d.person_seq = prod_fac_inspections.person_seq_inspector)
Again, it works perfect in Reports! It eliminates having 3 reports on the menu. This one report gives the user the option of selecting dynamic parameters.
Also, I got so frustrated, that I went a different route of using a default where.
I am stuck with the error of ORA:00933 SQL command not ended properly
1=1
I set the initial value to 1=1 and it does not like it.
I am stuck!

Unable to return value from LOV to the text field

I have created the LOV and attached in the database text item. I have done the mapping to the require field in the LOV properties and I was able to show the LOV whenever reach that field by press F9 with all the records in my query. However, when I try to press enter to select one of the data in the LOV screen, the data was not return to the column which I have defined the LOV. What's wrong with this ?

Lim,
Check is there any KEY-LIST-VAL trigger has any code. And Also check by assigning the same value to a dummy item for testing.

Pass the results from a selection formula to the default values for a parameter field

Post Author: kevans
CA Forum: General
Crystal 10 u2013 SQL 2000
I want to create a parameter field that will display all of our IT Departments so the end user can select the one they want to run the report against, such as IT-Security, IT-Network, etc. about 40 in all. BUT I donu2019t want this to be a static list where I type in all 40 depts in the default list, I was hoping I could do something more dynamic such a formula field that says u201C if {group.name startswith u2018ITu2019 then {group.name}u201D and then have the parameter field pull from this source.
Iu2019m sure this has been answered in a previous post but Iu2019m not finding it. I see stuff on creating a record selection formula such as u2018if {?group} like u2018IT-Secur*u2019 thenu2026u201D but this leaves too much room for error if people donu2019t type the name correctly. Maybe Iu2019m not using the record selection formula correctly? Sorry if I offend anyone but I just upgraded from 8 to 10 and thought for sure this option would be in 10, perhaps built right into the parameter default value page where you can place in select criteria but NOTHING has changed.

CA Forum: General
if you are creating the parameters in the rpt file, it will only pull values you enter, or directly from the database
in the record selection you can do something like this, so if they only enter the first 2 characters it should pick up only the IT etc.
(if eft(,2)={?parameter} then true else ={?parameter})

Parameter Field Value returns "no records"

I am using Crystal 11 and am new to Crystal but not to other Reportwriters. I have a Crystal report that has 2 parameter fields, one is "Enter Date" that prompts for the start and end date, the other "Select Items" prompts for the supply Item Numbers to be included in the report. In the "Edit Parameter: Select Items:" edit/create parameter dialog, the Select Item parameter has "Allow Multiple values" and "Allow discrete values" set to true. The report runs fine and returns any items entered in the "Select Items" prompt that has usage during the start & end date. My problem is ... if the entered Item Number for the Select Items parameter returns no records, I cannot report that Item Number as having zero usage. I cannot find a way at the time of report running to identify and report the "not found" items. I would also like to report the Start and End Dates parameters requested, but cannot, the Enter Date parameter returns an empty parameter field across the whole report. I'm sure other users have had this problem of reporting the requested parameter values. Need assistance.

Jeff's answer is one way to do it. There are others:
If you want the items with no data interspersed with the other items (say, in item number order), then you'd change the report to use your item master table and do a left join from that to the usage data. If a field from the usage table is null, then there was no usage, and you can condition a message based on that.
Or, if your parameter selects item numbers without some type of "ALL" option, then you can use arrays to keep track of which if the selected items printed. Then in the report footer, compare the list of items reported to the parameter items, and show which item numbers had no usage. (This might run a tad faster than the separate subreport that Jeff suggested - but maybe not...)

Filtering report data based on user login and Parameter fields

Post Author: mronquillo
CA Forum: General
Hi,I am running a report that filters data based on the user login. To do this, I created a formula called @user that compares the login name (using the CurrentCEUserName field) and returns the user's name. If the user login is not a login specified in the if statements, it returns the parameter field "user_name":For example: if CurrentCEUserName = "loginname1" then "User's Name 1"else if CurrentCEUserName = "loginname2" then "User's Name 2" else if CurrentCEUserName = "loginname3" then "User's Name 3" else if CurrentCEUserName = "loginname4" then "User's Name 4".. .else {?user_name} In select expert, I have a condition which filters data based on the string returned from that formula:{Table.Name} = {@user} This works fine and when the users run the report they only their own data. However, they are still prompted to choose a parameter field regardless if of the value returned by the @user formula. Oddly enough, regardless of what parameter field they choose, they will still only see their own data (i.e. if John chooses "Bob" from the parameter list, he will still only see John's data.)If I remove the "else {?user_name}" line from the @user formula, then the users are not prompted anymore. However, if they are not a "valid" user - that is, if any of the if statements in the formula are not true for their login name - then they will see no data. What I want to do is make the report ONLY prompt the user to choose a parameter field if their login name is not "valid". That is, if the @user formula is able to return a string value for their login name, then they will jump right into the report without being prompted to choose a parameter - otherwise, the user will be prompted to choose a name from the parameter list. I thought my formula would allow this (hence the "else" clause), but it seems that if a parameter field is present in any formula, then the report automatically prompts the user to choose a parameter. Is what I am trying to accomplish possible in CR (I'm using CR v10.0) or is there a better way to do what I am trying to do?Thanks in advance.

How to use a parameter field value as a substring in a "like" statement?

Hi all,
I'm trying to use a parameter field in a Record selection formula where the parameter field value would be a substring of the data stored in the field.
My parameter field (SlctResearcher) is constructed as follows:
Type: string
List of Values: static
Value Field: (Reports) RptAuthors
(in Value Options) Allow custom values?: True
{Reports.PubDate} in DateTime (2009, 04, 01, 00, 00, 00) to DateTime (2010, 03, 31, 23, 59, 59) and
{Reports.RptAuthors} like "*{?SlctResearcher}*"
When I hit F5 to generate the data, I get no results (and the parameter prompt field does not even come up...)
If I modify the formula to put a hard-coded string, like
"*Jones*"
after the 'like', I get results (all the reports where "Jones" is a substring in the RptAuthors string.) If I modify the formula to just use the parameter field without the quotes/stars like:
{Reports.PubDate} in DateTime (2009, 04, 01, 00, 00, 00) to DateTime (2010, 03, 31, 23, 59, 59) and
{Reports.RptAuthors} like {?SlctResearcher}
I do get the parameter prompt field, but still no results even if I put in a valid substring value (since it is not searching for a substring anymore...)
How can I do this?
Thanks,
Will

1st thing... Make a copy of your report before doing anything!!!
To use a SQL Command, you'll want to open the Database Expert and look at the Current Connections. Expand the data source and the 1st option you see is the Add Command option.
To find the SQL That CR is currently using, choose Database from the menu bar and select Show SQL Query...
You can copy this and paste it directly into the command window. (If you you can write your own SQL you don't need copy CR's, it's just an option.)
You'll also want to take not of any parameters that you have, you'll need to add them the the Parameter List of the command as well... be sure to spell them EXACTLY as they are in the design pane.
Anyway, once the SQL statement is in the Command window you'll be able to alter the WHERE clause to use the wild cards.
For future reference... What type of database are you reporting against???

Get the parameter fields defined in crystal report

I am porting my application from crystal 8.5 written in C++ to crystal 2008 in .net.
Here I am not making use of crystal report viewer neither I am creating .rpt in .net code.
I have a set of already created .rpt files.
I have written a function in .net to export the crystal report.
Its a generic function and will be called for multiple crystal reports.
I am passing the parameter values to the report by making use of the following function :
     ReportDocument repDoc;
     repDoc.SetParameterValue(APPTYPE, strNextToken[0]);
     repDoc.SetParameterValue(COMPORROLETYPE, strNextToken[1]);
Similarly I are setting other parameter values.
The problem here is that, all the reports do not have parameter fields defined that I am trying to set.
They may be present for one report and absent for another. In this case , if the report does not have a particular parameter
field, then it gives error on setting parameters and subsequently fails.
Now I want to find out through code what all parameter fields are defined in the report. Then I will only set those
parameter fields?
Please guide how can this be done.
Thanks
Sonam

Not as trivial as you might think. You will have to loop through all the sections of the report looking for the objects you need. I don't have a code specific to parameters, but looping through al the sections would be something like the code below. But... this will only show you parameters in a section. It will not show you parameters used in a formula, record selection formula, group selection formula, text field or a conditional formula. In order to get those parameters, you's have to parse out each of those objects looking for parameters. And this is probably not an exhaustive list of places to look for a parameter in the report. I get a headache just thinking about this...
Dim crSections As Sections
Dim crSection As Section
Dim crSubreportObject As SubreportObject
'set the crSections object to the current report's sections
crSections = crReportDocument.ReportDefinition.Sections
'loop through all the sections to find all the report objects
For Each crSection In crSections
crReportObjects = crSection.ReportObjects
'loop through all the report objects to find all the subreports
For Each crReportObject In crReportObjects
If crReportObject.Kind = ReportObjectKind.SubreportObject Then
'you will need to typecast the reportobject to a subreport
'object once you find it (***you'd go to setting the parameter here - or not...)
crSubreportObject = CType(crReportObject, SubreportObject)
'open the subreport object
crSubreportDocument = crSubreportObject.OpenSubreport(crSubreportObject.SubreportName)
'set the database and tables objects to work with the subreport

Parameter Field Value Elimination Based on Another Parameter

I'd like to make 3 grouping parameters with static values to produce 3 drop downs in the user prompt. The problem is, I'd like for the second drop down to eliminate the choice made from the first drop down and the third drop down to have been eliminated to only one choice. Is there a way to edit the parameter field values from the formula workshop?...Or maybe this would be better handled in the group selection formula area. Any help would be very much appreciated.

Can't be done unless you use one of the 3rd-party Crystal viewers listed at http://kenhamady.com/bookmarks.html
A simpler approach is to have a record selection formula that causes no records to be retrieved if 2 parameters have the same selected value. You can then unsuppress a text object telling the user their parameter selections can't be the same.

Modify default value for static parameter field programmatically

Hi,
I have my Crystal Reports stored in a BO Enterprise system. I have written a java programm that scans the repository, loads the CR reports one by one into a ReportClientDocument, modifies the data source and then stores the updated report back to repository (it overwrites the existing objects).
I was even able to modify the default values for the parameters, which are used for scheduling of each report.
But what I am trying to do know is to overwrite the default value used when invoking the report interactively. This should be the value found under the Default Value field, when the Properties window of the parameter is opened in the CR designer.
This is what I have tried so far:
Option 1: First I tried to set the default values using com.crystaldecisions.sdk.occa.report.application.ReportClientDocument.getDataDefinition().getParameterFieldController().getField(...).getDefaultValues() . The only thing I have managed to do using this approach is to modify the static LOVs that are associated to static parameters. The actual selected value (shown under Default Value in the Properties window for the given parameter field) remained unchanged, when invoking the report in the InfoView or opening it in the CR designer.
Option 2: I have used com.crystaldecisions.sdk.plugin.desktop.report.IReport.getReportParameters().get(ik).getDefaultValues() to change the default values. I was able to see my changes in the BO repository (using a query on CI_INFOOBJECTS), still the changes did not really have an impact to what is displayed as default value when invoking the report in the InfoView.
Any help will be appreciated.
It would be great to know if someone of you has already implemented successfully such a use-case.
Regards,
Stratos

Parameter field usage with an ACT! database

Hello,
I have tried using the parameter field functionality in Crystal Reports 2008 with an ACT! database, but it doesn't work. I have used parameter fields with other databases and did not have this problem, so I don't know why it's not working, unless this functionality is not supported with an ACT! database. Any help would be greatly appreciated.
Thank you.
Edited by: training 2go on Dec 14, 2009 12:57 PM

I ran the report and let it sit for at least 10 minutes, but it did not retrieve any records or produce an error message.
The table has 200 records and should only retrieve 26 records.
I'm not sure that I understand your question about whether or not the record selection is being pushed to the database.
The ACT database is on my laptop and so is Crystal Reports. If you tell me what to check, I will gladly do so.
Is there a list of known issues with Crystal when using an ACT! database? I ask because there is other Crystal functionality that does not work with an ACT! database.
Thank you.
