Report - empty value problem (-)

Hey
When I have me report, I have a few fields who are empty but displayed with a '-'.
Is there any way I could remove this?
I'm asking because in the report is a link that passes back 3 values together, if one is empty i have a '-' that is passed back.
Thanks in advance.

You can set the null display value In your report attributes. Look in the "Layout and Pagination" section for "Show Null Values As".

Records with a picklist field with empty values can't be seen from a report

Records with a picklist field with empty values can't be seen from a report. I've created a report that have a picklist as a column. When there is no values the record(s) associated to this picklist don't appear. Do you know what are the common causes for this event?

Hi samrat chakraborty ,
go to SUIM > roles > roles by complexselection criteria>
under the selection according to authorization values give the object's form SU53 screen and press enter it will asks the values for given object pass the values as per the SU53 and execute it will give the list of roles.... capture the roles. The user gets access if you give the any one of the listed roles is assigned, assign the role as per your approval process.

Show rows with empty values

Hello,
We are creating a cross tab report, with products as the columns, and relationship managers with direct and shared revenue displayed across the rows.
For Eg
Relationship Manager    Coverage         Product1   Product2   Product3   Product4
Bob                                Direct                 100,           0,               35,            50
                                      Shared                0,              0,               15,            0
Alex                               Direct                  15,            25,             40,            10
                                      Shared                5,              0,               5,               0
George                          Direct                  0,               0,              0,               30
                                      Shared                0,               0,              0,               5
The problem lies when either one of the products has no values, or one of the relationship managers has no direct or shared revenues. If one of the products has no revenues, it disappears, and also when one of the RMs has no direct or shared revenues, the Direct or Shared row disappears.
I have tried to create a second query just included the Coverage variable, and using this variable in Query 2 with the RM variable from query 1, along with checking the "Show Rows with Empty Measure values", "Show Rows with Empty Dimension Values" and "Show when empty", but it still does not appear to work.
It only shows rows with values in them, and shows the rows with empty values at the end with no RM.
I have not tried to solve for empty columns yet.
Help with this would be much appreciated!!!!!!!!
Thank you

Hi ,
I think you can resolve this issue following ways ,
you need create another query ( Ex :Qauery2 ) add Product object and RM (Direct,shared) object only without conation. So now query2 result wil have all product and RM(Direct,shared).
Merge the Product object and RM between query1 and query2
Now create table using Product and RM from query2 and measure value from query1. Now you will get row even there is no data.
If you want try this sample report using efasion unvierse.
1) Add year ,state and Discount objects and apply condition Year Not in list "2004" and state Not in list "California "
2) run this query and create the cross tab table . Now you will not get 2004 column and California row in table.
3) Create query2 add Year and State only without any condition , run the query. Now query 2 will display all state and year .
4) Merge the column Year and State between query1 and query2
4) Create the cross table ussing Year and state from query2 and Discount from Query1
Now cross table will show 2004 and California ,even there is not in query 1.
I hope this will help you.

Plot empty point in line chart with previous non empty value

Hello,
I have a problem to plot series data in SSRS line chart, with the empty point, I don't want use average and zero provided by the report builder, I want use the last non empty data to fill the empty point, tried to use expression =Previous(Field!Value), no
luck, any one have some good idea?
P.S. do not want to use query to fill the null with previous non null value, just from the performance point view. at last , the chart should have some line as square wave with different height, if I use average for empty point, it shows slop wave line which
is not reflect the real production.
Thanks
Richard

Hi Richard,
In Reporting Services, if the chart type is a linear chart type (bar, column, scatter, line, area, range), null values are shown on the chart as empty spaces or gaps between data points in a series. By default, empty points are calculated by taking the average
of the previous and next data points that are not null.
If we want to use previous value to replace the empty value, please refer to the following steps:
Right-click the field which displayed in Y axis (Height) to open the Series Properties.
In the Value field to modify the expression to look like this:
=iif(isnothing(Sum(Fields!Height.Value)),previous(sum(Fields!Height.Value)),sum(Fields!Height.Value))
The following screenshot is for your reference:
If there are any other questions, please feel free to ask.
Thanks,

Passing null/empty values from a actionscript VO to a Coldfusion ORM object

This is the situation.
If you have an actionscript VO that binds to a Coldfusion ORM object via the RemoteClass metadata and some of the values are not set, null, or empty strings and you pass it from Flex to Coldfusion then the Coldfusion deserialization barfs saying the values are not acceptable date values (for type="date") or valid emails (for validation="email") or other such validations, even if required="false" on the property.
For instance, if you have the following actionscript VO:
package vo
    [RemoteClass(alias="com.companyname.Person")]
    [Bindable]
    public class Person
        public var person_id:Number;
        public var last_name:String;
        public var first_name:String;
        public var email:String;
        public var created_date:date;
     public function Person() {}
And you have the corresponding Coldfusion component:
<cfcomponent displayname="person" output="false"
    alias="com.companyname.Person"
    schema="dbo" persistent="true"
    table="PERSON">
    <cfproperty name="person_id" type="numeric" fieldtype="id" validate="integer" required="true" column="PERSON_ID"/>
    <cfproperty name="last_name" type="string" column="LAST_NAME" required="true"/>
    <cfproperty name="first_name" type="string" required="true" column="FIRST_NAME"/>
    <cfproperty name="email" type="string" validate="email" required="false" column="EMAIL"/>
    <cfproperty name="date_created" type="date" required="false" column="DATE_CREATED"/>
</cfcomponent>
Then if you pass the actionscript VO as is to Coldfusion, the deserialization complains that you do not have a valid email or a valid date for date_created. This is bad, bad, bad. Essentially if you have a validation of certain types (email being one) or a date property, or probably some other cases, then you essentially can not make it not required, it automatically makes it required because the Coldfusion serializer considers null/empty values as invalid dates or emails. But the serializer should not care for values that are not required, there has to be a way to pass null/empty values to these data types, but apparently there's not. If you pass an empty string ("") you still have the same problem. I know Coldfusion does not have null values, but there has to be a way to do this, otherwise it defeats the purpose of having required="false" and some kind of validation on the property.
There seems to be two ways around it. One is to override the implicit setters for the properties on the Coldfusion side and check for 0 length values yourself, then set the property if it is not, or create your own validation routine. I ended up creating my own validation function since I didn't want to have to write a setter function for everyone of these cases and I can pass back user friendly validation messages.
Have other people encountered this problem? How have you gotten around it? Thanks.

I realize that I didn't clarify that I am using ColdFusion
for getting the data. This class was generated by the Create CFC
wizard in Flex Builder.
package com.generated
[Managed]
[RemoteClass(alias="components.generated.clients.Clients")]
public class Clients
public var clientid:Number = 0;
public var clientfirstname:String = "";
public var clientlastname:String = "";
public var clientaddress1:String = "";
public var clientaddress2:String = "";
public var clientcity:String = "";
public var clientstate:String = "";
public var clientzip:String = "";
public var clientphone:String = "";
public var clientemail:String = "";
public function Clients()

Looks like a known workaround to this issue is to wrap the Flex object in an array.
The ColdFusion CFC will accept that as an array, with the first an only element being a struct, which is the object you built in Flex.

Remove null & empty values

I created a report with multiple fields. I would like to create a generic formula in which it evaluates all the values and if it found a null or empty value it will be replaced by a 'N/A'. I was searching in the forums and I found the following formula
if (isnull() or ( ='')) then
"Display the required text"
else
when I tried to use it i had an error that the value must be boolean. Is there is a way where I can change all the fields as string?? and a assign "N/A"
or
how can I assign a "N/A"to a boolean field??
also I have approx. 140 fields to evaluate, does the formula can be generic or I will need to create a formula for each variable??
thanks

Usually when Crystal runs across a field that is NULL, it immediately stops executing the formula, unless the field is enclosed within IsNull(). However, I'm not sure if that is the case for a parameter being passed to a function. So, you may be able to create a function like (Formula Workshop -> Create Custom Functions -> Add; basic syntax):
function DisplayString (inVal as string) as string
if (isnull(inVal) or (inVal ='')) then
DisplayString = "N/A"
else
DisplayString = inVal
end if
If Crystal does stop when passing a NULL value as a parameter, then you could code a similar function (without the isnull()), and check the Convert NULL Database Values to Default option on the File -> Report Options panel.
You would need to create one such function for each data type that you want to show "N/A" for, and for data types other than string, convert the value to a string when it is not null.
These functions could then be used in the Display String formula for the field on the report.
The only other way I can think of achieving this would be to base the report(s) on an SQL Command and convert NULL values to "N/A" there. It might be a bit easier to do in an SQL Command, but probably not a whole bunch.
Or, educate your users that when nothing is printed, it means that it's not applicable!

How to define null or empty value in BAPI function modules?

Hi,
I have problem with BAPI functions, where some parameters are mandatory.
For example: when I try to use HR BAPI's(BAPI_PERSDATA_CHANGE, etc.) I have to insert parameters like SUBTYPE,OBJECTID,LOCKINDICATOR. The PA0002 table that is used from this BAPI doesn't have SUBTYPE, OBJECTID, LOCKINDICATOR, for any of the records that I would like to select.
So what I tried, was to put a ' ', to indicate that is empty. It returned an error message saying "Make an entry in all required fields". Next tried to put in some values for these fields -- and it returned an error message saying "No data selected from 0002 for this period".
I also tried to run BAPI_FAMILY_CHANGE that uses data from table PA0021. Here I found some records with SUBTYPE, OBJECTID fields that were not empty, but LOCKINDICATOR was still missing. So I tried to put LOCINDICATOR value directly in to database (with MS SQL Enterprise Manager). After that I was able to use BAPI_FAMILY_CHANGE.
I think that manually inserting data in database is not normal procedure.
Is there something that I have missed out?
I mean -- how can I get this to work without inserting data directly in database?
How can I define null or empty value in BAPI function modules?
Thank you in advance.
Best regards,
Mihail

Defining an empty value for a parm in a table is easy.
First get the function's definition from the SAP system
Second only populate the fields for which you have a value to set
Third execute the function.
The JCO takes care of the rest.

How to accessing current row report column value in Lov Query?

Hi,
which access methods (eg. bind variables, substitutions, ...) for getting the current row report column value can be used in the "Lov Query" property of a report column?
As what I know of and what I have read on the forum there are no bind variables for the report columns. For the "Link Text" property it seems that the column values exist as substitution strings (#COLUMN_NAME#). But they don't work in the Lov Query. => And would be good because of a hard parse each time the Lov query is executed.
The following post (Re: Simulating a correlated sub query in lov
is showing a solution to use package variables for temporary storage of the referenced value, but the only problem with that solution is that if a new record is added with the "Add rows to tabular form" process the package variable still contains the value from the last queried row! Is there a way (variable, APEX package, ...) to determine if the lov query is executed for a new record so that the package can return null?
I know that I could write the package in a way that the value is immediately cleared when lov_pkg.keyval is called (one time read), but then I would have to create several variables if I'm accessing the value multiple times in the query or in another query => I think an one time read solution would be very obscurely.
Thanks for your help

Hi Patrick,
I agree that it's a waste to continually use Ajax to go back to the server to get the contents of a dynamic select list.
There are no bind variables for any row item - but what you do have, as per my previous post, is the value of the data entered by the user in the first row. You can pass this into your application process (using get.add("VARIABLENAME", value)), which can use it to retrieve the correct LOV in your Ajax code - this will give you a "bind variable" that your process can use.
What you could do, however, is generate hidden select lists on your page - one for each possible LOV list and replace the contents of the new row's select list with the contents of the appropriate hidden select list. This is easy to do with javascript (using innerHTML functions). Obviously, though, the usefulness of this depends on the number and size of the select lists.
Even if you don't generate them to start with, you can keep a copy of any select lists returned by Ajax in the DOM for use on new rows. So, if you have retrieved a select list, you will have a copy of it in DOM which you can then copy into the new row. If you don't have the list in DOM, use Ajax to get it, store a copy of it and copy it into the new row.
Which method you use will depend on the number/size of select lists needed. If they are few in number and/or size, I would suggest generating hidden lists. If they are large, use Ajax to get them once, store them and then retrieve them from the DOM when needed.
There is another thread here where Arie recommends going to the server every time to make sure you get the most up-to-date data for the lists. If you want to follow this advice, for this reason, use get.add("VARIABLENAME", value) to pass the value to your process. If this is not an issue, you can use one of the other methods I outlined above.

Andy

Column link - call java script & assign current report column value to item

Hi,
How to call java script and assing current report column value to item?
I have a button column in the report to 'delete' the selected row.
I want to first show dialog box with message 'Are you sure?'. If yes, process to delete
will be executed, else no action.
In order to fire JS, I used Column Link ->Target=URL.
Problem: The alert is showing but I don't know how to pass selected row's primary
key value to process (to delete selected row).
I have a item which can be used to store selected primary key value but don't know how to assign the value
when button pressed.
Thanks in advance
Dip

Ok. The issue has been resolved by following way.
PAGE PROCESS: delete_request
begin
delete xyz
where id = :P8_id;
commit;
end;BUTTON URL:
javascript: DelRec(null,'CREATE', 'f?p=&APP_ID.:8:&SESSION.:delete_request:NO::P8_id:#id#');Java Script:
<script language="JavaScript1.1" type="text/javascript">
function DelRec(msg, req, url){
var confDel = msg;
if(confDel ==null){
confDel= confirm("Are you sure?");
}else{
confDel= confirm(msg);}
if (confDel== true){
redirect(url); }
</script>

Passing Interactive report item values to flash chart.

Hello,
I am trying to pass an interactive report item value to a 2D column chart type in the chart query as :IR_EMPNO but the item value comes as null and the chart does not show any data. when I am passing this value to another form item and referencing it in the chart query as :P2_EMPNO, it works fine!! have anyone encountered such problem? Please help.
Regards.

Thank you Varad...
Unfortunately, I am still getting no data found. (and there IS data).
a) Do you mean in the link column section of the report attributes? that is done: item 1 name= IR_P2_FID, value = #FID#
b) Do you mean my changing my hidden page item to ir_p2_fid with its source value as #FID# ? also done.
Do I need this hidden item?, and if not how do I refer to link in the where clause of the called page's sql region?
3) Where Fishery_id = :IR_P2_FID
Where Fishery_id = &IR_P2_FID
Thanks again!

Dynamic Heading not translated in report template "Value Attribute Pairs"

Hello,
I created a report in which I use application item names in the column heading of the items.
When I use the report template "Value Attribute Pairs" the heading displays not the contents of the application item names but the exact contents of the headings.
for instance:
application item name "trm_label_1" has the value : "Naam".
I created a report based on the SQL: select x.name from persons x
The heading of column "name" is: "&TRM_LABEL_1.".
The report shows the text "&TRM_LABEL_1." instead of "Naam".
When I change the report template in "Standard" the substitution is done well.
Can anyone explain what (not) happens and how I can fix this problem?
Gr.
Rob

Hi Rob,
You can do this by choosing as Headings Type: PLSQL in the Column Attributes.
You would have something like Deptno:DName:Loc:&APP_ITEM.
Where the first columns are normal text and the last one is an application item.

Dimitri

I would be greatfull for any help

I have managed to solve the problem.
In the end I didn't check if the values were empty, as it worked fine without. However the switch of the price didn't work in combination with the rest of the query.
I've solved the problem as follows:
$varCategory_rsgetsearch2 = "%";
if (isset($_GET['Category'])) {
$varCategory_rsgetsearch2 = $_GET['Category'];
$varMake_rsgetsearch2 = "%";
if (isset($_GET['Manufacturer'])) {
$varMake_rsgetsearch2 = $_GET['Manufacturer'];
$varColor_rsgetsearch2 = "%";
if (isset($_GET['Color'])) {
$varColor_rsgetsearch2 = $_GET['Color'];
$varPrice_rsgetsearch2 = "%";
if (isset($_GET['Keysound_price'])) {
$varPrice_rsgetsearch2 = $_GET['price'];
mysql_select_db($database_dBconn, $dBconn);
$query_rsgetsearch2 = sprintf("SELECT * FROM products WHERE Category LIKE %s AND products.Manufacturer LIKE %s AND products.Color LIKE %s", GetSQLValueString("%" . $varCategory_rsgetsearch2 . "%", "text"),GetSQLValueString("%" . $varMake_rsgetsearch2 . "%", "text"),GetSQLValueString("%" . $varColor_rsgetsearch2 . "%", "text") );
switch( $_GET['price'] ){
        case '0-500':
        $query_rsgetsearch2 .= ' AND price BETWEEN 0 AND 500 ORDER BY price ASC';
        break;
          case '500-1000':
        $query_rsgetsearch2 .= ' AND price BETWEEN 500 AND 1000 ORDER BYprice ASC';
        break;
                    case '1000-2000':
        $query_rsgetsearch2 .= ' AND price BETWEEN 1000 AND 2000 ORDER BY price ASC';
        break;
          case '2000':
        $query_rsgetsearch2 .= ' AND price BETWEEN 2000 AND 10000 ORDER BY price ASC';
        break;
$query_limit_rsgetsearch2 = sprintf("%s LIMIT %d, %d", $query_rsgetsearch2, $startRow_rsgetsearch2, $maxRows_rsgetsearch2);
$rsgetsearch2 = mysql_query($query_limit_rsgetsearch2, $dBconn) or die(mysql_error());
$row_rsgetsearch2 = mysql_fetch_assoc($rsgetsearch2);
I'm sure that you can keep the checking for values in, however for me the was no need for it anymore.
Thanks for all your help
