POJO data source refresh

Hi
I am using POJO as the data source and dynamically loading data (datbase controller) from a CSV file to the POJO to report and then exporting the reports to the different formats (pdf, rtf, etc.,) using Java code.
My question is if a report is designed already using a POJO given to me and later the POJO is changed (let us a field name is added or deleted) then how that is going to effect the report. How will we refresh that fields in a report again and add/delete the fields compatible to the updated POJO. When I try to do this, the only way I saw was to add the updated POJO again and remeove the old one. But it actually deletes the entire info of the old POJO. Is there a way that I add updated info with the old data (or info) being there in my report. Not having two POJO on my report. Instead updating the POJO in my report.
Thanks
Lal

Please re-post if this is still an issue to the Java Development - Crystal Reports Forum or purchase a case and have a dedicated support engineer work with you directly

Problem sharing POJO Data Source while exporting

Hi, 
I have an issue that stops me exporting a report to PDF. I have two reports that share a POJO data source. The POJO is stored in the session. The same POJO is being passed to both of the reports. While one of the them exports it perfectly the other one fails when the reports are opened simultaneously. It does not fail if opened alone. Given below is the error. I would like to know if there are any limitation that would stop exporting a report when sharing a data source concurrently.

This is a Plain java object with getters and setters. . Below is the sample
public class Test_POJO {
 private String advantageDis;
 private int vehCount;
 private int driverCount;
 private String agentNumber;
 private String accountInfo;
 private String accountType;
 public String getAccountInfo() {
 return accountInfo;
 public void setAccountInfo(String accountInfo) {
 this.accountInfo = accountInfo;
 public String getAccountType() {
 return accountType;
 public void setAccountType(String accountType) {
 this.accountType = accountType;
 public String getAdvantageDis() {
 return advantageDis;
 public void setAdvantageDis(String advantageDis) {
 this.advantageDis = advantageDis;
 public String getAgentNumber() {
 return agentNumber;
 public void setAgentNumber(String agentNumber) {
 this.agentNumber = agentNumber;
 public int getDriverCount() {
 return driverCount;
 public void setDriverCount(int driverCount) {
 this.driverCount = driverCount;
This object is on the session with values. This POJO is shared by 2 reports. When I run the 2 reports simultaneously. One of them fails. If I try to access one at a time then it works.
thanks,
Ravi

Sharepoint 2013 Excel External Data Source Refresh Issue

I have been facing this issue for quite some time now.. i have created an Excel sheet in Excel-13 and have imported data from an external data source [SQL server 2012].
Everything is working fine, with the excel sheet on the desktop. Data refreshes, every-time i open the excel file and also at regular intervals that i have configured in the data source properties.
The problem begins when i save that excel sheet on my sharepoint server. the issues that i am facing are :
1. Changes made into the original data source, are not reflected immediately inside the excel sheet inside the browser. after 5-10 minutes, it reflects the changes..
2. The data doesn't refreshes automatically. After i update my data inside the sql server table, i have to manually trigger the refresh of the data connection when viewing the excel sheet inside the browser, even though i have marked "Refresh when opening
the file", and refresh every 1 minute inside the excel sheet. Any solutions ??
I have been troubled a lot by this issue, and seek for some quick solution.. Any help here ??

I found the solution finally, my self ..
Issue - 1 : It's going to take atleat 5-minutes to refresh the data connection, that is generally not a big time span.
Issue - 2 :
--> Set Your connection to refresh everytime the file is opened. go to internet explorer -> file -> internet options -> general -> Browsing History -> Settings -> Check for newer versions of stored pages... Check 'Every time I visit the
webpage'.
Now everytime i update your original data source, wait for 5-10 minutes and refresh my web page containing the excel sheet.. The Contents of the excel sheet are updated as desired..

Use of Arrays in POJO Data Source - CR4E

Hi,
I would want to use arrays in POJO's that is used as data source. Given below is an example POJO
public class POJODataSource {
     private String[] vehUsgType;
     private String[] soundRepro1;
     private String[] finRespType ;
     public String[] getFinRespType() {
          return finRespType;
     public void setFinRespType(String[] finRespType) {
          this.finRespType = finRespType;
     public String[] getSoundRepro1() {
          return soundRepro1;
     public void setSoundRepro1(String[] soundRepro1) {
          this.soundRepro1 = soundRepro1;
     public String[] getVehUsgType() {
          return vehUsgType;
     public void setVehUsgType(String[] vehUsgType) {
          this.vehUsgType = vehUsgType;
Does CR4E recognize arrays in POJO's. If so How do we use it in the report. An example of how to use and iterate thry the arrays would be appreciated.
thanks,
Ravi Narala

POJO Factory doesn't support arrays, or hierarchial indexed properties.

POJO Data Source where POJO includes reference to another POJO

All of the samples and webinars I have seen that deal with using a POJO as a data source, use a POJO that includes int, String, or Date fields. Suppose you have an OrderItem class, which contains a product (class Product) and numOrdered (type int). The Product class has a description and so forth. Is it possible to use both POJOs in the report? For example, can you link the two classes together? In the demos I've seen, one POJO is dragged to the report, then a productId is linked to a column in a database table. We want to design reports that are database-independent, so we would like to use POJOs. Also, can you use POJOs in reports outside of Crystal Reports for Eclipse?

Hi,
I am new to Crystal.
I have similar requirements as the original post. POJO in Crystal is useful only when you can transparently deal with your existing POJO model and navigate all the relationships you need for the report. If I have to "flatten" complex object graph of my complex POJO model, then what benefit am I getting here?
We already have mechanism in our webapp to populate our POJOs with data from our Database using JPA/JDO queries. Basically, we dont want to hardcode any SQL or direct knowledge of database.
ReportMill (another report engine) lets you navigate all relationships in your OO model as you would in any Java class. Without such support, for each report, I have to "somehow" flatten complex model into essentially a "Row" object to satisfy Crystal? Is that what I am hearing?
Someone please help with what is possible or what is not.
Thanks

Update Data source - Refreshing to clear cash is greyed out - DPM 2012 R2 UR5

Hey guys,
I have problem with a DPM Server after updating to UR5.
The new button "refresh" within the DPM console replaced the clear button, seems to be blocked.
Or in other words.... the Cache is still active and I can't clear the Cache.
Now I see old machines they don't exist anymore and some new ones won't showing up within the console.
I couldn't find a specific cmdlt or something. Any ideas about that?
oh... btw. there's no "cacheinquiry" reg entry under configuration. Shouldn't be there anymore If I remember. (since R2)

For the Moment the Troubles are gone.
After checking a couple of other DPM 2012 R2 i could see, that the CacheInquiryResuts Key is still there (I thougth there was a change during SP1 to R2 but it turns out I was wrong) and there were heaps of cached machine stored.
What I've done:
I created the key CacheInquiryResuts under HKLM\Software\Microsoft\Microsoft DPM\Configuration
After that I putted a DWORD aka REG_DWORD called InquiryResultsTimeoutInterval into it and changed the value to 1 (hour).
Now I see new fresh machines and the older one with moved storage aren't telling me error Messages about missing paths anymore.
There are 2 screenshots to clarify what I mean.

Crystal Reports Developer Edition XML or Java data source

Is there a way to use XML or custom Java objects (POJO) data source in Crystal Reports Developer Edition ? Currently Crystal Reports is being invoked as API from an existing code. But that code can be modified if need be.

Hello Jayashree,
please see a sample for CR 08 with XML as datasource [here|https://smpdl.sap-ag.de/~sapidp/012002523100006016532008E/XML_datasource.zip].

Refreshing the Data Source View in Analysis Services

I have added columns to the SQL Database table that is used as a dimension in an Analysis Services Cube. The new columns will be used as additional Property Fields for the dimension. When I attempted to refresh the Data Source view so that the additional columns are present, I am given the following error:
System.Data
Property not accessible because 'Parent Columns and Child Columns don't have type-matching columns'
I have done nothing to the columns used for the parent of child and the error message provides nothing to gon on. Does anyone have any ideas on this?
Gary

Olga,
Thanks for your response. I will try and answer your questions
1) I have not tried removing the columns yet. I will try that this afternoon but have limited hope. The two columns I added are simple text columns that will be used as attributes in the dimension. I have made no change to the parent or child columns.
2) The table I modified is the source table for a parent-child dimension.
3) The reference to the "check list" does not take me to any kind of check list.
4) The parent-child dimensions I am trying to modify have been in use for months and the parent and child columns do have the dame data types.
5) I have also check the data types between the dimension table and the fact table. they use the same data types (small int).
6) I have not made a collection for the parent key, it is a single column. The remainder of your last paragraph is not clear to me. Can you give me an example.
I am fairly inexperienced with Analysis Services, please talk slow and use small words :-)
Thanks again for your help!
Gary

Unable to refresh SQL Server data source through Data Management Gateway

I just installed the version 1.1.5226.8 of Data Management Gateway and tried to refresh a simple query on a table connected to SQL Server, with no transformations in Power Query.
This is the error I obtain:
Errors in the high-level relational engine. The following exception occurred while the managed IDataReader interface was being used: transfer service job status is invalid.
I am wondering whether my Power BI is still not updated to handle such a connection type, or there could be something else not working?
I correctly created the data source in admin panel following instructions in Release Notes, and
test Power Query connection is ok.
Marco Russo http://www.sqlbi.com http://www.powerpivotworkshop.com http://sqlblog.com/blogs/marco_russo

I made other tests and I found important information (maybe there is a bug, but read the following).
The functions DateTime.LocalNow and DateTime.FixedLocalNow
work correctly, generating these statements to SQL Server:
    convert(datetime2, '2014-05-03 06:37:52.1135108') as [LocalNow],
    convert(datetime2, '2014-05-03 06:37:52.0525061') as [FixedLocalNow],
The functions DateTimeZone.FixedLocalNow, DateTimeZone.FixedUtcNow,
DateTimeZone.LocalNow, and DateTimeZone.UtcNow
stop the scheduled refresh with the error I mentioned
in my previous messages, generating these statements to SQL Server:
    '2014-05-03 06:37:52.0525061+02:00' as [TZFixedLocalNow],
    '2014-05-03 04:37:52.0525061+00:00' as [TZFixedUtcNow],
    '2014-05-03 06:37:52.1135108+02:00' as [TZLocalNow],
    '2014-05-03 04:37:52.1135108+00:00' as [TZUtcNow]
I solved the issue by placing the DateTimeZone calls after a Table.Buffer call, so query folding does not translate in SQL these functions. However, it seems like something to fix.

to report started a manual refresh it was success, after next schedules it failed.
Error massage:
Errors in the high-level relational engine. The following exception occurred while the managed IDbConnection interface was being used:
The network path was not found. ;The network path was not found. The network path was not found. .
A connection could not be made to the data source with the DataSourceID of '82f49f39-45aa-4d61-a15c-90ebbc5656d',

Thank you very much !

If you are using Claims Auth then this is a known limitation. Auto refresh only works under Classic Auth.
I trust that answers your question...

In the Power BI Admin Centre, the data sources that cannot be setup with Analysis services, and it has the error to schedule the powerpivot or powerview report to have data refresh. The error is "我們無法重新整理此報表中的資料來源種類。" - english, "We
can not rearrange the source of information in this report types ." We would like to know the power bi schedule function can support SQL analysis service or not. Please advise. Thanks.

It is not currently supported. You might be able to create a linked server in SQL to be a proxy for the connection and enable scheduled refresh if you are desperate.

Refresh data source view gets 'column' argument cannot be null

When I try to refresh a data source view in SQL Server 2008 BIDS, I get the error: System.Data 'column' argument cannot be null. Parameter name: column. How to resolve this? The underlying tables have no data yet.

Hi PCSQL66,
The error message should be caused by FOREIGN KEY constraint auto-generated. If you
add a FOREIGN KEY to the generated table, then you will see the error message after clicking refresh button. Please submit this issue to below official link and then post the link back here, I think we need to get confirmation from product group.

SPM: Using "refresh data sources" in Data Source Administrator

Hi All,
When making changes to a query, that I want to be reflected in the flex front end, I carry out the following steps:
1) save the query in query designer
2) load up the SPM user interface, navigate to Administration -> Data Source Administration
3) Click on "Refresh All Data Sources"
4) Wait for the "wait" cursor to finish (only takes a few seconds)
5)log out of the portal
6) clear the browsers cache
7) reload the web page
8) Repeat Steps 2-7 again
9) the query's changes are not reflected in the UI
Does anyone know what I should be doing differently so that the query changes are reflected in the Data Source?
Kind regards,
Neil

Hi Neil,
You are almost right on the steps, just a few changes.
1. Modify your query and save the query changes.
2. Close the query designer so you are not locking the query (optional step, but recommended).
3. Go to transaction RSRT and generate the query (optional step, but recommended).
4. Login to portal and launch SPM user interface, navigate to Administration -> Data Source Administration
5. Click on "Refresh All Data Sources"
6. Check the UI logs (Settings > View logs), to confirm that datasource refresh has finished successfully (your should receive messages saying 'Metadata Loaded'. The cursor will turn into a clock multiple times, this is the UI checking to see if the metadata refresh has finished. You should see the message 'Metadata Loaded' as many times as there are registered BW queries. This could take a few minutes depending on the number of queries registered in SPM UI.
You need not clear your browser cache or logout of the application. At most you may need to relaunch the application.
These steps should be sufficient to reflect any query changes to the SPM UI.

Rohit

Portal language refresh / reload (user data source ABAP stack)

Hello,
I'm on SAP NetWeaver Portal 7.0 with user data source on ABAP stack.
I'm trying to create simple JavaScript links for changing the Portal language.
I was able to change the ABAP stack user's logon language by BAPI call.
But the newly set language shows up only after the user logs out and logs in again.
I know that in the WebDynpro for Java, which implements the UME user interface, there is a functionality, that allows that relogging of the user is not necessary. After setting the language you only refresh the browser page (F5) and the new language shows up.
Does anyone know what function I should call, for the language refresh (could be the same as in UME standard WDJ)?

Hi Andres,
language doesn't change on the Portal. The content remains in the previous language.
I know that the switching of Logon language parameter in the user profile in ABAP stack and logoff and login on the portal leads to change of the language on the Portal. But I don't know, how to do it without the relogging of the user.
I change the Logon language in ABAP by AJAX call of BAPI.
Thank you for any idea.
Jiri
