How to validate the input parameters in Oracle BI Publisher reports

Hi
i am new to Oracle BI Publisher
I am using OBI for generating simple reports.
here i need validation for input parameters (Date Parameter) and also want to disable the Date filed so that user can select through the calendar component.
Here validation in the sense, the system must validate the date and alert the user with an appropriate message
Can anyone please provide me the solution in detail.
Thanks in advance

I have the same task to validate input parameters with Oracle BI Publisher 5.6.3 running under Oracle eBS 10.5.10.2. My validation goes beyond of what I can do during parameter registration. I am using Data Templates.
My first logical place was the before report trigger. So, I built a report trigger which returns 'false' in case the parameters are not proper. Guess what... XMLP just returns a hard-coded message
!!Error : trigger '" + datatrigger.getName() + "' returns status as 'false'
First of all, this is a bad style to hardcode messages visible by the user (especially during French implementation). Second of all, it is not informative at all. It would be nice to change oracle.apps.xdo.dataengine.XMLPGEN.executeTrigger() to read, for example, a message from the message stack when the trigger returns 'false' and let the user read it.
Anyway, what I did was I built a special data group, decalred before any other data group, query like
select my_package.my_validation fro dual
If parameters fail the validation my PL/SQL package throws an application exception with a message. At least, in this case the error message gets available as the description of the concurrent request.
I wish the before report trigger worked!!!

How to keep the input parameters in a query (WAD report)

In some WAD reports, we have to record the report name and the user name (which user use the report) and what the selection criteria the user input. How can we do?
Thank you
Michelle Lee

Hi.
Report name: create user exit variable (lets say Z_QUERY_NAME) with following code at I_STEP=2
WHEN 'Z_QUERY_NAME'.
DATA lv_compid TYPE rszcompid.
CLEAR lv_compid.
IMPORT compid = lv_compid FROM MEMORY ID 'COMPID'.
l_s_range-low = lv_compid .
l_s_range-sign = 'I'.
l_s_range-opt = 'EQ'.
APPEND l_s_range TO e_t_range.
User name: crate user exit variable (lets say Z_USER) with following code at I_STEP=2
WHEN 'Z_USER'.
CLEAR l_s_range.
l_s_range-low = sy-uname.
l_s_range-sign = 'I'.
l_s_range-opt = 'EQ'.
APPEND l_s_range TO e_t_range.
Then in WAD create 2 InfoField webitems. Set dataprovider and select variables for info fields.

How to disabled the input parameter dialog box in crystal reports 9

Post Author: Murtaza
CA Forum: General
Hi friends,I have got stuck with a weird problem. In my
crystal report, I have set up some input parameters. I am setting
values for these parameters somewhere inside code. But I don't
want to show the default input parameter dialog box. Under any case,
user should not see the ugly parameter dialog box that crystal
presents. Please suggest me how I can achieve
this. I cannot do this through code, because our environment does
not allow that. I have to do this in crystal reports viewer and
by setting some property of the crystal report object. But everything
must be done on UI, not through code. So, the solution should not be the following.
// step before step 1
// **** the line needs to refer to the report and be set before setting
ReportSource in the viewer to myReport
myReport.EnableParameterPrompting = False
Any help would be greatly appreciated. Murtaza

Hi Murtaza,
Unfortunately, I am not aware of any method to suppress the prompt for the input parameters, but still use them. It is truly a design-related issue for the report. The reason that the prompt appears is because the parameter it is prompting for is used in the report; in particular either the Group or Record Selection, or referenced in another formula.
The only way I can think of to not show the prompt, is to not use the parameter in the report. You did mention that you are setting the value of the parameter inside of the report -- are you doing this through using a formula? Perhaps you can just remove the parameter and only use the formula that you are setting the default values with.

There are two ways to achieve ur task.
1.By checking for all alphabets.in this u need check all the alphabetic characters one by one.Refer the following
http://www.shiningstar.net/articles/articles/javascript/javascriptvalidations.asp?ID=ROLLA
http://www.shiningstar.net/articles/articles/javascript/checkNumeric.asp?ID=AW
2.By using regular expressions.its very easy and a single line code.here u need to specify single expression for whole alphabets.Refer this
http://aspzone.com/blogs/john/articles/173.aspx
Everything has been given for validating in javascript.i hope u also validating in javascript only.

What are the input parameters for Function Module

Dear Experts,
I want to generate a Sales Tax returns report,those fields are not available in my existing Datasources.
For that i want to write a Generic Datasource with Function Module.
audat
bukrs
vkorg
vtweg
spart
aurat
auart
netwr
mwsbp
kschl zedp(consition type)
kschl zvat(condition type)
ksch zcst(condition type)
matkl material group
Here what are the Input parameters for Function Module.
Thanks in Advance.
Srinivasan.

Srinivasan-
For creating a Generic extractor based on a FM, you first of all need to know what is going to be your structure.. i.e. what all fields you need to pull from what all tables. A functional consultant may help you identify the exact DB tables.
Once you know them, hand over the requirement and the pdf mentioned by Krishna to the ABAP guy, he would be able to take this up further.
Also decide 1st whether you would be using a full load or delta. There is a slight difference in the way they are built.
Let me know how it goes.

How to Validate the Cube in Essbase

Hi All,
in Essbase How to Validate the ASO Cube. How can we validate the data is loaded correctly or not after data loading.
please let me know how to do this job?
Regards

If you load data you can see the data load successful and the no of cells updated in the dialogue box.
If there any records rejected they are thrown into dataload .err file.
If you want to validate the input data you can verify the input records in the excel add-in.
If you want validate the business logic ( ie data at the high level ) you have to write SQL Procedures or Custom programs at the Source layer to calculate the high level data in ESSBASE and compare the results in essbase Roll UP Using Excel add-in.

Please do the needful how to do it.If you want to validate at entry level then use When-Validate-Item trigger and check the input and show message. Like
If :quentity <0 then
message('do not enter negative value');
message('do not enter negative value');
raise form_trigger_failure;
end if;Why u open same thread again ? not closing one.. check this one

The code looks good.
Here is a sample based on your use-case:

          </f:facet>
          <af:inputText label="InputText" id="it1"

How can validate the ASM size and free space correctly?

Dears ,,
I faced problem in ASM size as it appeared in alert file as below
ORA-19504: failed to create file "+DG_DATA"
ORA-17502: ksfdcre:4 Failed to create file +DG_DATA
ORA-15041: diskgroup space exhausted
So we resize ASM space and large it. But we faced the same problem also although there is free space in ASM.
It seems that the shown free space is not real.

I was having this problem. Im my case i couldn add datafiles to a tablespace despite the fact that i was having a lot of space in the asm. Try rebalancing. It might help. In my case rebalancing also didn work because it seems that there need to be a threshold space in all the disks for the rebalancing to happen which was not in my case, so i had to shrink some unused space in the tablespace and then after gaining the required space I rebalanced the disk and then the disks got rebalanced, also i was able to use the free space that was showing .

Validate the input file against a given schema inside an orchestration and producing 2 different files based on the validation result

HI All,
I have a situation.
I need to validate the input file against a given schema inside an orchestration and producing 2 different files based on the validation result.
A predefined success schema in case of validation success and negative schema structure for validation failure.
any advice ?

Hi Rachit,I following the blog
http://dietergobeyn.be/validating-biztalk-messages-orchestration/ and stuck in few things
I created a helper class with the name Validation and following code
[Serializable]
public class Validation
private bool _isValid = true;
public bool Validate(XmlDocument document, Type schema)
XmlSchemaSet set = new XmlSchemaSet();
if (typeof(SchemaBase).IsAssignableFrom(schema) && !schema.IsNested)
set.Add((Activator.CreateInstance(schema) as SchemaBase).Schema);
ValidationEventHandler eventHandler = new ValidationEventHandler(HandleValidationError);
document.Schemas = set;
document.Validate(eventHandler);
return _isValid;
private void HandleValidationError(object sender, ValidationEventArgs ve)
_isValid = false;
public static bool ValidateMessage(XLANGMessage msg)
XmlDocument xDoc = new XmlDocument();
xDoc = (System.Xml.XmlDocument)msg[0].RetrieveAs(xDoc.GetType());
Type t = typeof(Schemas.External.Invoice_v3_1);
Validation validation = new Validation();
return validation.Validate(xDoc, t);
First thing, Do i need to write the ValidateMessage method inside the helper class or not ??
If inside, how to add the reference of schema files in the statement (Type t = typeof(Schemas.External.Invoice_v3_1);)
I tried adding the reference of my schema project but it is showing error.
And what is to be written in the ValidateMessage expression shape in Orchestration ?
Really appreciate your help.

How to use the POST method In Oracle APEX 3.1

Hi,
In APEX if we are submitting the page the parameters( Variables ) will pass through URL.
How to hide the these parameters from URL??
I Hope POST method will solve this problem.
How to use the POST method in APEX???
Help me out to solve this problem.
thanks in advance.
Cheers,
Shan

In APEX if we are submitting the page the parameters( Variables ) will pass through URL.No they won't. Submission POSTs the <tt>wwv_flow</tt> form.
Sometimes a branch may be performed after submission, generating a URL in which parameter values are visible. To avoid this, use the save state before branching option.
Other actions—like using navigation lists, or clicking a link in a report—will perform a GET using parameters in the URL. In these cases using Session State Protection is advised.
