Programmatically changing data in the JClient

I'd like to be able to change data in a JTextField and have that change reflected in the database.
My JTextField is bound to a ViewObject's attribute using iTextField.setDocument(JUTextFieldBinding.createAttributeBinding(...
Now I can change the attribute directly with:
panelBinding.getApplicationModule().findViewObject("ViewName").getCurrentRow().setAttribute("AttributeName", aValue)
but I want to sub-class JTextField and programatically change it's value (in response to a specific user-gesture)
without being aware of the binding that's in place.
If I use setText() or getDocument.insertString() then the change isn't noticed by the ViewObject.
How can I do this?
Tony.

Thanks for the replies.
I'm really not happy about firing a focusLost() call. I'm not sure how some listeners might react if they haven't previously had a focus gained() and get (several) focusLost()s.
Secondly, we use focusLost to change the apearance of the Component and would now need some way of supressing that action.
As to actionPerformed(null), I can't find any mention in the JavaDocs of this method on a JTextField.
Once again I'm surprised by BC4J's inability to do what must be a fairly common function.
I don't see why the JUTextFieldBinding.createAttributeBinding() method doesn't create a DocumentListener that correctly handles all document changes, instead of listening for focus events on the JTextField.
In fact I don't see why BC4J needs to create/change the Document at all. It seems to me all that's necessary is a binding object that implements DocumentListener and RowSetListener (or maybe RowNavigationListener), adds itself to the relevant Document and RowSet and responds to events as necessary.
Maybe I'm missing something, but surely BC4J should be connected to the "model", not the "view" in this MVC pattern? If it were so connected, I could easily have my own subclass of Document to implement my particu[i]Long postings are being truncated to ~1 kB at this time.

Changing Data in the Cells in webanalysis

Hi
Iam trying to change Data in the cells,in my report for the combination's which i didn't have data it is showing as (-99).
according to my functionality '-99' means 'NO',my USER is asking instead of showing -99 it has to display 'NO'.
I tried to change the display from -99 to 'NO' through "CONDITIONAL FORMATTING" but it was not happening can anybody plz gave me the solution how to change the display.

Hi,
When you execute your report, You press right button in your mouse over the column. Later, you select Analyis Tools->Analysis Tool Manager.
A box appear on your screen and you press double click in the column format (that you need) , another window appears and you press a button called Data Format.
A window appear and yo find the label "Substitution" (Or something like that) and you select Text and put the text that you need.
I don't know if You'll understand... but I can send you the images with steps.
PD: My options are In spanish and maybe the configuration is a little different in English.

Time delay on seeing the changed data onto the webi reports

Hello,
I'm new to BOBJ and was hoping someone can help me with adjusting the time delay the reflects the changed data to the Webi reports.
I have a user that would update a form on our EP. Afterward, she would have to wait a while before she can see the changed data on our Webi reports.
can you please tell me the default time lag and show me where I can change it if required?
thanks.

Thanks for the reply.
Our BO is 3.1 SP4.
We just implemented PBF (Public Budget Formulation) and our forms are running on NWCE server. It's being written to our backend BW 7.01 SP8 server. I was told by our users that after she updates some new information on the form, it takes a while before she can see it on the reports. My understanding was the universe should see the updated data from our BW immediately after they refresh. Just as you both mentioned. But according to the users, its not. there's a time delay.
I'm going to test this myself if there's a delay. In the meantime and suggestion would be helpful.

Sales Order creation/ change date for the items

I have a unique scenario and i need to get a Report for this
A sales order is created for 4 line items.
Out of these , for 2 line items a delivery is created. I need the sales order creation date and time for these 2 items in a custom report
Now the other 2 items go in to some kind of block- Now these are released by going in the sales order VA02 and after releasing the delivery is created. Again for these two items , i need the sales order change date as after a user goes and changes the sales order to remove the block only then delivery is created for these two items
Also another scenario is the 2 line items go for back order and when we get stock at tht time system confirms the stock and then the delivery is created for these. So also for this when this change occured i need to get the date for these 2 line items
Can any one please suggest how to get this data from the scenarios?
I dont want to get the date when the delivery is created as i can get tht from the LIKP table. I need the sales order create and change dates for these.

You may be aware, any changes to a document will be recorded in CDHDR (for header changes) and CDPOS (for item changes). You can explore these two tables.

Can you programmatically change properties of the Detailed Navigation?

Is there an SAP EP6.0 API call to allow one to programmatically change the width of the Detailed Navigation, or programmatically hide or unhide it? I realize that this can be preset, but I am interested in dynamically changing these values.
Thanks,

Hi!
If you look to the sourceCode of your EP (rigthClick->show source) you'll see that some JavaScriptFiles are loaded. One of them is called:
"WAandNavPanel.js"
Inside this file are some nice functions like "collapsePanel()" and so on. I didn't try, but perhaps you can use them or they can show you the right way.

Capturing the changed data in the interactive forms through HTML Viewer

Dear all,
I'm showing the Interactive Adobe form in the HTML Viewer and I want to capture it back after the user enters data in the form and save it to application server.
Can I get some help on this. Please attach supporting documents if any.
Regards
Aravind

sorry i've got no document describing this. under service.sap.com/adobe you'll find a lot of Adobe content.
But basically use the Adobe Designer from program files\adobe\design 7.0\formdesigner.exe
create new form based on the CAF tutorials in the Interactive Forms section, add a new data connection to a wsdl, bind input/output parameters to form fields and get a button executing the wsdl operation.
create your interactive form callable object based on that template, configure the form to start process and as impersonalized form. create the form from the GP administration screen, download it and test it.
...And Good Luck!!!

Tableview getting refreshed when changing data in the rows

Hi Gurus,
Iu2019m doing a BSP with MVC. The requirement is as below.
In the main page there is a button u2018Create Orderu2019, to create a sales order, once I click this button, another screen (pop up) comes up and within that I have a Tableview display with the below fields with the data of 20 records.
Material no
Quantity
Delivery Date
Here user is allowed to choose the quantity and delivery date by selecting each row.(with MULTISELECT option in BSP)
The issue is after I select first row and change the quantity and date, and if I click on second row, the Tableview gets refreshed to enable the second row to be editable and the changes what I did on the first row are also refreshed.
So i want the Tableview not to be refreshed when selecting the multiple rows. So that I can keep the changes I make to the quantity and date fields Can you please suggest any method.
Cheers,
Srini.

Hi Srinivas,
You need to capture the value entered by user in Quantity and date field and update the internal table with these values for the current selected row.
For ex.
The tableView code is like:
                      <htmlb:tableView id                  = "material"
                                 headerText          = "<%= otr(Z_SUS/HEADER_TEXT_MATERIALS) %>"
                                 headerVisible       = "true"
                                 design              = "alternating"
                                 onRowSelection      = "MyEventRowSelection"
                                 selectionMode       = "MULTILINEEDIT"
                                 width               = "880"
                                 filter              = "SERVER"
                                 emptyTableText      = "<%= otr(Z_SUS/EMPTYTABLE_MATERIALS) %>"
                                 iterator            = "<%= iterator %>"
                                 table               = "<%= gt_materials %>" />
In eventhandler OnInputProcessing :
DATA: lt_fields type tihttpnvp ,
           ls_fields like line of lt_fields.
call method request->get_form_fields
            changing
              fields = lt_fields
Now the internal table lt_fields contains all the editable cell values , just update the internal table of your tableview with these values.

Powershell Change date to the first day of last month whenever i run the script.

If I run the script on 2/4/2013 or any other day in February I want the date to be change to 1/1/2013. I am replacing date on line 59 with this value.
Get the content of the CMS Script.
$CMSReport = Get-content C:\reports\CMSReport.acsauto
Go to line 59 and replace the date for Last Month date.
$CMSReport[58] = $CMSReport[58] -replace "([1-9]|0[1-9]|1[012])- /.- /.\d\d", [datetime]::Today.ToShortDateString() $CMSReport | Set-Content C:\reports\testCMS.acsauto
Run the CMS script
Invoke-Expression -command "c:\reports\testCMS.acsauto"

PS C:\> $lastMonth = (get-date).AddMonths(-1)
PS C:\> $firstDayOfLastMonth = get-date -year $lastMonth.Year -month $lastMonth.Month -day 1
PS C:\> "{0:yyyy-MM-dd}" -f $firstDayOfLastMonth

Hello AbqBill,
Thanks for getting me there. I am a lot closer to the final goal. I input what you suggested and I am getting different results as you. here what I did.
$LastMonth = (Get-Date).AddMonths(-1)
$FirstDayofLastMonth = Get-Date -year $LastMonth.year -month $LastMonth.month -day 1
$CMSReport = Get-content C:\reports\CMSReport.acsauto
$CMSReport[58] = $CMSReport[58] -replace "([1-9]|0[1-9]|1[012])[- /.]([1-9]|0[1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d", "{0:dd/MM/yyyy}" -f $FirstofLastMonth
$CMSReport | Set-Content C:\reports\testCMS.acsauto
I get 12/1/2013. Which bring me to 2 questions. How will this solve when it is January and it has to put last month last year? and why is it going back two month instead of 1?

9iAS: Programmatically change data source for Java/J2ee bc4j application

Background: We obtain a copy of our customer's live data daily for support issues. We'd like to be able to keep up to date as possible and get files early in the morning. due to the size of the database, it takes a few hours to download and import into our Oracle database. what I'd like to do is use two different schemas/users for the data, alternating on each day so that the loading of one, does not affect the running of the other. To make this seamless, I'd like to have a script perform the changes after the download and restart the server. The issue is how/where to change the data source so that my application will pick it up each time? I'm using an application specific data source from EM.
Any ideas?
Thanks,
Jeff

Hi Venkat,
Use the appropriate sort key in the GL to fill up the assignment field automatically.
U can create ur new sort key through OB16

Programmatically Change DataBindings.cpx

Hi
I am using JDeveloper 11.1.1.3.
I have been trying to programmatically change data source connections in one of our applications. I first tried doing it in the application module. I could successfully create a new root AM, and query the new database, but was not sure of how I could refresh the VO to show the data from the changed database.
My second attempt was to create 2 separate AM's. I then added the VO to a JSF page and in the bindings created a pageFlow scope parameter, which I programmatically populated from a drop down list. This was successful. However that requires the development team to duplicate the AM's for each database exactly.
So my next attempt would be to have only one AM and try and change the configuration in the DataBindings file. The reason I would like to attempt this, is when I click on a DataControl in the DataControl Usage section of the DataBindings file, I see that in the Property Inspector for the DataControl, there is a Configurations property drop down list that contains all the available configurations for the AM. I would like to know if this can be accessed from code at runtime.
Any advice on how to achieve this or if it is possible would be welcomed.
Regards.
Leon.

how to get changed data?
Edited by: Ki-Joon Seo on Dec 27, 2007 6:04 AM

Hi,
To get only the changed data in the ALV grid of a WD, you need to capture the "ON_DATA_CHECK" of the ALV grid.
To this please do the following in the ALV initialization of the ALV table settings :
    lr_table_settings->set_data_check(
            IF_SALV_WD_C_TABLE_SETTINGS=>DATA_CHECK_ON_CELL_EVENT ).
You may also do this:
    lr_table_settings->set_data_check(            IF_SALV_WD_C_TABLE_SETTINGS=>DATA_CHECK_ON_CHECK_EVENT)
The above two ways would depend on when do you need to check for the changed data. If you want to check the data as soon as it is entered, then use the first method. Else, use the second method.
You need to register an EVENT HANDLER for this event.(You may do this in your VIEW or Component Controller).
In this Event handler, you would find an importing parameter R_PARAM which is a ref type of      IF_SALV_WD_TABLE_DATA_CHECK.
The attribute T_MODIFIED_CELLS of this interface IF_SALV_WD_TABLE_DATA_CHECK will contain the modified cells of the ALV with the old & new values.

Can not change data in Input Ready Query

All,
I have created an input ready query on an aggreagation level which has one transactional cube underlying it however, after run the query I am unable to change data in the cells even though I get a warning message saying query is ready for input
Note:
1. The underlying realtime cube is in "Planning Mode:Loading not allowed" state in rsa1
2. I tried including all characteristics so that the record can be uniquely identified at that aggregation level).
3. I am not using any characteristic restrictions
4. I have not set any data slices
5. I have set the property for Planning "Start query in Change Mode"
6. I have set the 'Key Figure' Planning Properties to "Can be changed Manually or via Planning Functions" for the key figures
7. I do not have currency/unit in row/column.
8. There are any locks occurring
Any pointers welcome.
Thanks,
Milind

Hi Milind,
Was wondering how was your problem solved. I get the same message when I run the query in web from query designer and in bex analyzer the cells are not updated with the changes that I make.
I am hitting my head against the wall to figure what could be the problem as my plan query is simply based on aggregation level created directlty upon the real time info cube.
Have cross checked all the points that you mentioned in this post but I cells do not change.
There should be some way around to solve this problem.
Thanks

Identifying Changed Dates on Documents in SAP B1

Greetingsu2026I have an unusual request that is somewhat long, very serious, and hope folks can help.
A headquarters customer believes a subsidiary company has u2018made upu2019 dates on invoices for previous billings. They describe the date changes as u2018radicalu2019 but I have not personally seen these invoices as of yet and am waiting a FAX. They requested I go into SAP B1 to see if someone has fabricated or made up or changed invoice dates and who it was. They have some specific large-dollar invoices identified to research. The person under suspect (who is no longer there) was considered an expert in SAP B1, so maybe she knew all of the different ways to change dates around. Being an expert means also she might have used some unusual ways to change dates to the ones she wanted.
Here are some of my ideas to discover this situation, but I hope someone can suggest even more steps because I would like to know every way that this situation can be discovered.
1. Open the AR Invoices and use Data > Change Log and concentrate on dates.
2. Run some SQL to validate document dates and system dates. SELECT T0.DocNum, T0.DocDate, T0.CreateDate, T0.TaxDate, T0.UpdateDate FROM OINV T0 WHERE (T0.DocDate does not equal T0.CreateDate OR T0.TaxDate does not equal T0.CreateDate). The results would show invoices that maybe had their dates changed.
3.Run a Document Journal in the Financial Module. Finance > Financial Reports > Accounting > Document Journal with the u2018Expanded Selectionu2019 of AR Invoices and a date range covering the invoices in question. Then see if the Transaction Numbers are out of sequence.
4. Run a Transaction Journal Report Financials > Financial Reports > Accounting > Transaction Journal Report with AR Invoices. Compare this report to Document Journal.
5. Run the Utilities functions of Utilities > Check Document Numbering to see if there any anomalies there in the document numbers.
6. Run the Administration > System Initialization > Document Numbering function to see if a special series has been set up.
7. Check out the AR Invoice numbering order by running another simple SQL covering a range of the invoices in question. SELECT T0.DocNum, T0.TaxDate, T0.CreateDate, T0.UpdateDate FROM OINV T0 WHERE T0.DocNum > 1583 AND T0.DocNum < 3251 ORDER BY T0.CreateDate. Then see if the AR Invoice Numbering Sequence is not consistent.
8. Check out those documents that are connected to each suspect AR Invoice and their associated dates by using the Target and Base Document icons. For example, if a Deliver Document has dates of January 2007 but the AR Invoice date is September 2006, then someone has played around with dates on at least one of the documents.
9. Get copies of the complete company database before the alleged changes were made and a company database as of today and compare the two contents. Only good if the backups are maintained for a long time.
Here come the questions on the ways I BELIEVE dates can be changed but not sure how to find and need to work on them:
QUESTION 1 u2013 If a person DTWs invoices up into SAP B1, how can I tell that DTW was used to change the dates, the date of the DTW run, and the dates that were changed?
QUESTION 2 u2013 If a person uses SQL to update dates on SAP B1, how can I find out that SQL has been used, the date of the SQL run, and the dates that were changed?
QUESTION 3 u2013 If a person goes out and changes the workstation and/or server Date and Timestamp Properties, how can I find that they did that and the date changes? You can do this on your PC by just changing the month, date, and year in Microsoftu2019s Date and Timestamp Properties.
QUESTION 4 u2013 I know SAP has a policy that no SQL can be used to update databases and/or tables and have been told some customers lost support because they did this. What does SAP do to discover this in their lab?
QUESTION 5 u2013 Are there any notes in the portals to help me find changed dates?
QUESTION 6 u2013 Are there any logs SAP B1 produces that can help identify such changes and how do I find and use them?
QUESTION 7 (and this is big) u2013 Are the other ways dates can be changed on AR Invoices and how would I uncover the way it was done and the needed information of Original Date and Changed Date?
Many, many thanks for any help provided since this is a serious situation. If you can make any suggestions it would be greatly appreciatedu2026

Hi Zal
If this person was an "Expert" on SAP Business One then the only way they would have changed dates would probably be directly in SQL itself. The best way to determine this would be to hope that they slipped up somewhere and forgot to change a particular date in let's say one specific table.
For invoices, start with the post date, doc date & create date. Then check each of these to the OJDT/JDT1 tables for any discrepancies. Next check the ADOC/ADO1 table for multiple instances on the invoice. If only 1 instance then check the create date, time & user as well as the aforementioned dates between OINV/INV1 & ADOC/ADO1. If multiple instances, check the dates from 1 instance to the next (This will indicate dates being changed in the system).
Next check the same dates against OINM table. If any of the dates do not tally then the SQL was changed directly.
Hope this helps. Let me know if you need further assistance.
Kind regards
