CR 2008 - Optional parameter prompts

Hi!
I sometimes use Optional parameter prompts in Crystal Reports 2008.
The main reason is to minimise user input in Selection Criteria Screen.
I have many subreports, and not all prompts are needed for all subreports.
If the user leaves the prompt blank, then a formula will set a default value for the user.
I usually put the optional prompt at the top, so that user needs only fill prompts at the bottom.
Here is an example:
I have a parameter field called "PreferredSortOrder"
The Edit screen reads as follows:
Type: String
List of Values: Static
Value:
    Original Order
    Description
Value Options:
Show on (Viewer) Panel           : Read Only
Prompt Text                              : Preferred Sort Order [Optional]
Prompt With Description Only : True
Optional Prompt                        : True
Default Value                             :
Allow custom values                 : False
Allow multiple values                 : False
Allow discrete values                 : True
Allow range values                     : False
Min Length                                  :
Max Length                                  :
Edit Mask                                   :
Show value or Description        : Show Value
My report works perfectly, even if I leave the parameter field blank
I now add another parameter field called "WhichWarehouse"
with exactly the same values as above.
When I run the Crystal Report, I get this message;
Error running Crystal Reports
The report runs only if I type a value in the "WhichWarehouse" prompt
(The "PreferredSortOrder" prompt remains blank)
I did exactly the same as before. Why does the 2nd optional parameter not work like the first?
What has gone wrong?
Thank you
Leon Lai
JUST ADDED
I just noticed that in the Field Explorer,
(a) There is a green TICK near the parameter PreferredSortOrder
(b) But no green Tick neat the parameter "WhichWarehouse"
What does the green tick mean?
Could this be the key to the mystery?

Hi Leon,
No green tick means that the prompt has Not been used in the report.
If the report has Subreports, and if the subreport also has a 'warehouse' prompt then it could be this prompt that is causing the issue. You should link both the warehouse prompts to make sure you're only prompted once.

Missing Parameter Values CR2008 Optional Parameter

Hi,
I am getting "Missing Parameter Values" error
"CrystalDecisions.CrystalReports.Engine.ParameterFieldCurrentValueException: Fehlende Parameterwerte. ---> System.Runtime.InteropServices.COMException (0x8004100E)"
if I try to export a Report with an optional Parameter without setting the parametervalue.
The Report works fine with ReportViewer.
If I uncomment the "Parameterpart" and set a parametervalue it works fine, but it should works without a parametervalue too, its optional.

RecordSelectionFormula in Report:
(not HasValue({?Land}) OR {tab.location_code} = {?Land}) and
{tab.sup} = "XXX" and
{tab.Accounting_Period} = "200801"

You need to be careful when using optional parameters. If you are using the optional parameter in a record selection formula you'll need to check and make sure it has a value before you use it. There is a function call HasValue() that you can use to do this.
If you have an optional parameter in the record selection formula and you don't pass a value you'll need to make sure your selection formula can be completed with out it.
This is an excerpt from our help file.
Crystal Reports supports optional parameters. An optional parameter is a prompted value that does not have to be supplied by the user.
Report designers should provide some guidance to the end user that a parameter is optional by adding this information to the prompt text.
Optional parameters are treated by Crystal Reports as optional anywhere within the report that they are used. You cannot set one instance of the parameter to optional and another to mandatory.
Note: After you set a parameter to optional, if you use the Select Expert, the system will automatically add the selection formula for you using the HasValue() function.
The Formula Workshop Editor does not automatically add the formula. Only the Select Expert automatically adds the formula for you.
If you change the parameter from optional to mandatory, the HasValue() function is not automatically removed from your formula.
Handling a parameter with no value
When the report engine evaluates any formula which references an optional parameter that does not have a value, it generates a runtime error. All formulas that reference an optional parameter should first use the HasValue() function to check if that parameter has a value before evaluating it. This includes record selection formulas and saved data formulas.
Note: The system will not automatically drop a statement from the SQL WHERE clause. It is the report designeru2019s responsibility to decide which statement to leave out based on HasValue() testing.

"when i am passing ... and OptionalInput as null"
What does that mean exactly? From the exception, it looks like you are just leaving the text box blank. For 'null' you have to check the 'null' check-box beside it.

How to set no_value to Optional parameter in XI 3.0 by OpenDoc URL linking

I found in "BusinessObjects XI 3.0 Viewing reports and documents using URLs Howto.doc"
"You can remove an optional parameter from the prompt by setting it to no_value in the OpenDocument query string."
I tested: response.sendRedirect("/OpenDocument/opendoc/openDocument.jsp?sIDType=CUID&iDocID=AaVxpKuKNBxKnHUJCqwuRi0&lsSCountry=""no_value""&token=" + logonToken);
But it will filter no data, because no country call "no_value". I still need to delete the value, and click Apply, to get all data.
I wonder how to achieve optional parameter via opendocument linking, to get a report with "full data set".
Any one can help?
Thanks in advance!
Jennie

Hi Jennie,
I'm wondering if "1203675 - Cannot specify an empty string for an optional string parameter through the refresh prompts page which displays "no value" unlike the parameter panel" is related to this.
Instead of using no value or empty string, how about if you use ALL value for the parameter to bring full data? Check "1218621 - Option "All" in list of values for a dynamic prompt in XI"

Nothing sane about this approach. Especially the decision not to use bind variables and slowing down cursor processing significantly by burning a lot more CPU cycles on hard parsing and fragmenting the SQL Shared Pool in the process.
Why not used MS Access instead? It is far more suited as a mickey mouse database for a goofy application?
Why am I badmouthing your approach to Oracle? Because that is exactly the primary cause, the #1 reason, for poor Oracle performance and run-time problems dealing with Shared Pool fragmentation. It is something that many Oracle experts blog about, talk about, write about. It is addressed in numerous books, Oracle documentation, and even Oracle Support Notes.
And despite the amount of information available on how to get the basics rights in using Oracle... this approach you are pursuing still refuses to die. So it deserves to be beaten with a lead pipe when it rears its ugly head here in this forum..

How to use offset for select-option parameter ?

Hi experts
could anybody please let me know how to use offset for select-option parameter. i can able to use offset for table fields, variabiles and all , but don't know how to use for parameters.
following is my code
SELECT-OPTIONS: s_prctr FOR vbsegs-prctr OBLIGATORY.
here "prctr" length is 10.
i'm using two tables 1. vbsegd-bupla
                                2. vbsegs-prctr
here prctr+6(4) = bupla.
"Bupla" length is 4
SELECT belnr gjahr bukrs bupla sgtxt buzei FROM vbsegd INTO CORRESPONDING FIELDS OF TABLE it_vbsegd FOR ALL ENTRIES IN it_vbkpf
                                                             WHERE belnr = it_vbkpf-belnr
                                                               AND gjahr = it_vbkpf-gjahr
                                                               AND bukrs = it_vbkpf-bukrs
                                                               AND bupla IN s_prctr.
the above statement is not working as prctr and bupla lenths are different. here i want to use offset.
SELECT belnr gjahr bukrs prctr sgtxt buzei FROM vbsegs INTO CORRESPONDING FIELDS OF TABLE it_vbsegs FOR ALL ENTRIES IN it_vbkpf
                                                            WHERE belnr = it_vbkpf-belnr
                                                              AND gjahr = it_vbkpf-gjahr
                                                              AND bukrs = it_vbkpf-bukrs
                                                              AND prctr IN s_prctr.
this is working as prctr and s_prctr lengths are equal.
could anybody please help me out in this.
Thanks in advance.

Below code will work for you.

Passing optional parameter to subreport

Hi,
I am having a CR 2008 report based on BW query. The query has optional parameter (the value can be set to NULL). When I try to use this report as subreport in my main report, I am unable to pass Null(equivalent to set to NULL) to my subreport using subreport link. I tried blank and "" in a formula field and try to link it to the subreport parameter but it doesn't work. Kindly guide me in this regard.
Thanks and Regards,
Subbu S

Hi Subbu,
Try to create a formula and pass the formula value to your sub report parameter and in sub report record selection based on main report formula value try to filter the records.
Ex: Main report create the following formula :
Whileprintingrecords;
Shared Stringvar x;
If not hasvalue({?Optional}) then
x:='No Value'
else
x:={?Optional}
Now link this to your sub report parameter
In sub report record selection
If {?parameter} = 'No Value ' then true else {?Parameter} = FieldValue.
Thanks,

Optional Parameter without a value

Hi, I'm using Discoverer 10g.
Somebody knows what is passed when an optional parameter (a parameter which doesn't require a user to enter a value) is left without a value ?
I didn't understand actually if is passed NULL, 'NULL', '',' '...
I need to know it because I need to wrap this "value" in order to pass it to a function on the DB.
The user have to be the possibility to write something or leave it without a value.
Thanks
Alessandro

Hi,
While running the Discoverer Report, just leave the parameter as blank.
Discoverer passes it as NULL to execute the query.
In the function, where you are passing this parameter, use NVL() to defualt the NULL value. If you want to pass "this value" manually into function, you can still leave it as blank and NVL will take care of it.
Hope this helps!

Optional parameter workaround - dates problem

Hi
I use optional parameter workaround and it's fine.
but how I should use it with dates parameter or numbers ?
SAP note 1500777. This describes a workaround :
((not HasValue({?itemcode@select itemcode from OITM })
or isNULL({?itemcode@select itemcode from OITM })
or {?itemcode@select itemcode from OITM } = '')
OR {OITM.ItemCode} = {?itemcode@select itemcode from OITM })
Regards
Idan

Hi,
Optional parameter is not supported.
What I did was, I have 2 date parameter. pmDateFrom and pmDateTo.
In Crystal report record selection, OINV.DocDate in pmDateFrom to pmDateTo.
When running within SAP B1 8.8, if I want to include every dates, I put in a date in pmDateFrom (eg: 1/1/00) and do not enter anthing for pmDateTo.
That seems to work.

OPTIONAL PARAMETER WITH NO VALUE SELECTED

I have an optional parameter and I want to place the selected value in the Page Header. Since the selected value is a number, I want to give it a name. The problem I am having is when I don't select a value, my naming forumula doesn't work. I tried the HasValue function, but I don't think I'm using it properly.
// This did not work
IF {?SUPPLIER}= 10001 THEN "NESTLE PRODUCTS ONLY" ELSE
IF {?SUPPLIER}= 10005 THEN "UNILEVER PRODUCTS ONLY" ELSE
"ALL PRODUCTS"
// This did not work
If (not hasvalue){?SUPPLIER} then "ALL PRODUCTS" ELSE
IF {?SUPPLIER}= 10001 THEN "NESTLE PRODUCTS ONLY" ELSE
IF {?SUPPLIER}= 10005 THEN "UNILEVER PRODUCTS ONLY" ELSE
"NESTLE AND UNILEVER PRODUCTS ONLY"
Got any suggestions?

Hi,
Well if you select multiple values in a parameter and drag the parameter or the formula containing the parameter, then it would always display the first selected value.
Here's a dirty way:
If NOT(HasValue({?SUPPLIER})) then "ALL PRODUCTS" ELSE IF
ubound({?SUPPLIER}) = 1 then
        IF {?SUPPLIER}= 10001 THEN "NESTLE PRODUCTS ONLY" ELSE
        IF {?SUPPLIER}= 10005 THEN "UNILEVER PRODUCTS ONLY" ELSE
        "NESTLE AND UNILEVER PRODUCTS ONLY"
ELSE IF
ubound({?SUPPLIER}) = 2 then
"NESTLE AND UNILEVER PRODUCTS ONLY"
Let me know how this goes!

Optional parameter, no values

Hi,
I have an optional parameter in CR2008; I would like to print the choosen parameter values into the report header. This works great by using this function:
Join({?MyParameter},", ")
However, when no values were selected I get the error message "Parameter has no value".
So I adapted the function:
if hasvalue({?MyParameter}) then Join({?MyParameter},", ") else "All records"
The function is correct but I still get the error message (error dialog window).
How can I suppress the error message?
Thanks!

Ian,
Tip of the day: You can show the <> signs in the forum by using & lt; and & gt;. Just remove the spaces after the &.
It also works in code blocks...

I want to make DocNum as optional parameter.But since its data type is numeric I can not use
T1.DocNum='%[%1]'
In this case how can I make this numeric field optional.
Note-The square bracket is replaced by underscore in the above query.For eg,
'%[%1]'='% Opening square bracket % 1 Closing square bracket '

Dilip,
Are you saying that the user entering the DocNum is optional and if they leave the field blank they should still get the result. based on the other selection parameters
Since you are using DocNum = it will not be possible to have it optional but if you specify it as a range. example DocNum Between '[%0\]' AND '[%2\]' then we have a chance.
This is what I have for you to try
SELECT T0.FATHER, T0.CODE, T3.DSCRIPTION, T1.CARDCODE, T1.CARDNAME, T1.DOCNUM, T3.DOCENTRY, T1.DOCDUEDATE, T3.DOCDATE,
T0.QUANTITY AS 'BOM QTY',T2.QUANTITY AS 'PO QTY', T3.QUANTITY AS 'RECEIPT QTY', T0.QUANTITY-T3.QUANTITY AS BALANCE
FROM OPOR T1 INNER JOIN POR1 T2 ON T1.DOCENTRY = T2.DOCENTRY INNER JOIN ITT1 T0 ON T0.CODE = T2.ITEMCODE INNER JOIN
PDN1 T3 ON T3.BASEENTRY = T2.DOCENTRY AND T3.BASELINE = T2.LINENUM
WHERE T3.INVNTSTTUS = 'O' AND T0.FATHER LIKE '%[%0\]' AND T1.DOCNUM BETWEEN (CASE WHEN '[%1\]' = '' THEN 0 END) AND (CASE WHEN '[%2\]' = '' THEN 100 END)
AND T1.CARDNAME LIKE '%[%3\]' AND T1.DOCDUEDATE BETWEEN CONVERT(DATETIME,'[%4\]',112) AND CONVERT(DATETIME,'[%5\]',112)
ORDER BY T1.DOCNUM, T3.DOCENTRY
Note: Change the 0 and 100 with the DocNum range of your purchase order documents
 Quick tip to avoid the $ and % and [\] getting changed by the interface is to use a " \ " (Backslash)

Example:
FOR $\[$38.1.0] use $backslash\[$38.1.0]
FOR '[%0\]' use '[%0backslash\]'

Optional Parameter in Java.

Hi all,
I am new to java programming... I just wanted to know if we can have Optional parameter in java?. I searched few threads but not found any good result. Few suggested a overloaded method ,i think if it is not provided then there must be a big reason for that. Please let me know if anybody knows exact reason why it is not provied. I am using ver 1.4
~Amod .

class A{
     String a;
     String b;
     String c;
     public A(String a, String b, String c){
          this.a=a;
          this.b=b;
          this.c=c;
     public A(String a, String b){
          this.a=a;
          this.b=b;
          //String c will get a default value when this constructors get called
     public static void main(String args[]){
          A test = new A("a","b","c");
          System.out.println(test.a);
          System.out.println(test.b);
          System.out.println(test.c);
          System.out.println("-------");
          A test_ = new A("a","b");
          System.out.println(test_.a);
          System.out.println(test_.b);
          System.out.println(test_.c);
}Is that what you want?
