Can't delete matrix row in UDO form
Hi all,
i have a problem. I've already searched the forum and found a couple of solutions, but they didn't work.
I can't delete a matrix row. I'm on patch level 39, i've read that patches from 32 to 38 gave some problems with matrix row delete.
Any one has notice regarding same problems with patch 39?
I post the code i'm using for the delete.
matrix.FlushToDataSource()
dbDataSource.RemoveRecord(row - 1)
matrix.LoadFromDataSource()
UIForm.Update()
'Removes the change trace row
changeTrace.RemoveAt(row - 1)
UIForm.Mode = BoFormMode.fm_UPDATE_MODE
Thanks in advance
Hi,
I'm using PL39 and I can delete rows in matrix (you are right in previous patch there was an error, and it´s imposible to delete rows). I saw the code you put and I doesn´t undestand what you are trying to do. I explain what I do:
- I enable the menu 1293 to delete row in a matrix, in the menu event i put the following code
Dim oMtx As SAPbouiCOM.Matrix =
oMtx.FlushToDataSource()
This works for me.

Another Delete matrix row thread
I have read some threads with Q&A on the delete matrix row subject but I cant make it work properly. Deleted rows have a tendency to return.
I first tried to make my own:
If pVal.MenuUID = "RmLine" And pVal.BeforeAction = True Then
Set oMatrix = m_oForm.Items("MatrixM").Specific
i = 1
While i <= oMatrix.RowCount
If oMatrix.IsRowSelected(i) Then
If oMatrix.RowCount = 1 Then
oMatrix.AddRow
End If
oMatrix.DeleteRow i
m_oForm.DataSources.DBDataSources("@ITCCR_DM").Clear
oMatrix.LoadFromDataSource
m_oForm.Mode = fm_UPDATE_MODE
End If
i = i + 1
Wend
End If
Problem here is that I cant remove last row without having it return right after.(Thats why I tried the addrow)
Then I tried using SAP's function:
m_oForm.EnableMenu "1293", True
But as soon I hit "Update" the row returns so what do I need to add to the menu event to make it work?I use the two following standard methods for add and delete of rows... so far no problems with them (½ a year)
(Please not that I've have wrapped the entire UI for faster use, so not every method in here are core SDK, but hope you get the idea for the approach)
public int Add(B1ItemEvent pVal,B1DBDatasource Dbds, bool SwitchToUpdateMode, string ColumnToSelect) {
InnerMatrix.FlushToDataSource();
if(Dbds.GetValue_String(0,0)!="" || InnerMatrix.RowCount!=0) {
Dbds.InsertRecord(Dbds.Size);
Dbds.SetValue_String(0,Dbds.Size-1,"");
InnerMatrix.LoadFromDataSource();
InnerMatrix.Update();
if(SwitchToUpdateMode) {
if(pVal.IsFormModeOK) {
InnerForm.SwitchToUpdate();
InnerMatrix.Columns[ColumnToSelect].Focus (InnerMatrix.RowCount);
return Dbds.Size-1;
public bool RemoveSelected(B1ItemEvent pVal, B1DBDatasource Dbds, bool SwitchToUpdateMode, string WarningIfNoRowsSelected) {
InnerMatrix.FlushToDataSource();
int row = InnerMatrix.GetNextSelectedRow(0,BoOrderType.ot_RowOrder);
if(row!=-1) {
InnerForm.Freeze(true);
while(row != -1) {
InnerMatrix.DeleteRow(row);
if(InnerMatrix.RowCount==0) {
Dbds.BlankRecord(0);
row = InnerMatrix.GetNextSelectedRow(0,BoOrderType.ot_RowOrder);
InnerForm.Freeze(false);
InnerMatrix.FlushToDataSource();
InnerMatrix.Update();
if(SwitchToUpdateMode) {
if(pVal.IsFormModeOK) {
InnerForm.SwitchToUpdate();
return true;
else {

nullI opened activity monitor, closed all programs associated with pdf, preview, etc., however that didn't work. A simple restart did the trick. Even though I could see the pdfs on my destop the files were deleted. That explains why I couldn't manipulate the file. Somehow the file got caught in the graphics string.......????

How can I delete a row in access using the database toolkit?
I want to delete just one row of a access table using the database toolkit. Can it be done and if so How?
Take a look at page A-1 of the database connetivity manual. It has information on making a sql query that will delete. You will need to use this command with the dbtools execute query function. Look in the shipping examples for an example with this function.

HT201269 How can I delete all my data from former Iphone 4 for future sale on Ebay?
Hello!
I've just purchased an Iphone 5 from a new carrier. Now I should like to sell my former Iphone 4 but, obviously, removing all my personal data (contacts, photographs, etc.) . How can I transfer the ringtones that I purchased from by Iphone 4?
How can I do it? Thanks in advance.
Regards,
Mariabackup the device and restore it as new.
If you already have or don't need a backup:
Erase your device
Erasing all content and settings will delete all the data from your device, including songs, videos, contacts, photos, calendar information, and any other data. All device settings are restored to their factory condition.
To remove all settings and information from your device, tap Settings > General > Reset > Erase All Content and Settings. For more information about this feature, see iOS: Understanding 'Erase All Content and Settings'.
If you are unable to erase your device, restore the device using iTunes.
See: http://support.apple.com/kb/HT4137 for the exact steps.
Transferring ringtones isn't supported, as far as I know... -
I installed "Front Row" then I tried to erase it. I found everything of it (application, preferences, etc.) and I erased them. Now, after a month, when I start my computer, it appear ("Front Row") and I've to close it pressing "esc" key. It doesn't appear since I switch off my computer then I restart it. Thank you.
You may have to force quit the application running from the Activity Viewer/Monitor in Applications -> Utilities. Make sure it does not reappear. If it doesn't show in that application, go to Applications -> Utilities -> Terminal, widen the window full screen width, and type at the prompt:
ps -ax
There you should find the PID for the Front Row application on the same row as the Front Row application itself.
Once you know that PID number at the prompt type:
kill -15 PID number
If it doesn't let you kill it, try
sudo kill -15 PID number
All commands given in the Terminal should be followed by a Return key pressing. PID number will be one number, and you should use the number itself to substitute for wherever it says PID number in the instructions above.
Once you have verified Front Row is no longer running with
ps -ax
Deleting it should be possible. -
Can i delete redundancy rows in geometry column?
i had more geom data rows in table . it's repeat,repeat and repeat .
but i want keep single row for twinssssssss
the "distinct" and "group by" function can't help me...
please take a idea for me ?Hi,
for that case i would use SDO_AGGR_CENTROID or SDO_AGGR_UNION .
I had a similar problem where i had to determine, if geometries are redundant. I used here SDO_AGGR_UNION and then SDO_AGGR_CENTROID because i was not interested in one single point. Another way could be the use of SDO_WITHIN_DISTANCE or my favourite for searching duplicate geometries:
a selfjoin:
SELECT /*+ ORDERED */
b.<ID>, a.<ID>
FROM table_1 a, table_1 b
WHERE SDO_RELATE (a.<geometry>, b.<geometry>,
'mask=EQUAL querytype=WINDOW') = 'TRUE'
AND a.<ID> != b.<ID>;

How can I delete a row in datatable!
This is my code:
com.sun.jsfcl.data.DataCache.Row row =
dataTable1Model.getDataCache().get(dataTable1.getRowIndex());
row.setDeleted(true);
dataTable1Model.commit();
dataTable1Model.execute();
we use msSQLServer2000.Another way, to do this (here's a snippet from AppModel)
http://developer.sun.com/prodtech/javatools/jscreator/reference/codesamples/sampleapps.html
if your in your DataTable you have a column of
checkboxes. If you click on the checkbox and outside your
datatable, you have a delete button. Note, sel is the id of
the checkbox.
for (int rowIndex = dataTable1.getFirst();
rowIndex < (dataTable1.getFirst() + dataTable1.getRows());
rowIndex++) {
log("OnePage: check row " + rowIndex + " for deletion");
dataTable1.setRowIndex(rowIndex);
if (!dataTable1.isRowAvailable()) {
log("OnePage: no data available for row " + rowIndex);
break;
if (sel.isSelected()) {
log("OnePage: mark row " + rowIndex + " for deletion");
com.sun.jsfcl.data.DataCache.Row row = dataTable1Model.getDataCache().get(rowIndex);
row.setDeleted(true);
count++;
sel.setSelected(false);
// Perform the actual delete transaction and report results
try {
dataTable1Model.commit();
info("Total rows deleted: " + count);
} catch (Exception e) {
log("OnePage: Delete commit exception", e);
error("OnePage: Delete commit exception: " + e);
// Re-execute the query to pick up new results
try {
dataTable1Model.execute();
} catch (SQLException e) {
log("OnePage: Delete reselect exception", e);
error("OnePage: Delete reselect exception: " + e);
Refer to the AppModel for more info

How to add/delete rows on the form without saving data
I am new to apex
I am working on project and need some help on creating a form
my requirment is to save a request that has multiple questions.
i have a request form with multiple regions
On one of the region that takes questions, I want to create a tabular form such that i can add/delete/update row without hitting database and enter multiple questions
each row is one question.
Apex has the default functionality of having a tabular form linked to a table that onload shows the data from that table and also on click of add or delete hits the data base to save the data.
However i want to load a form that does not show any data if its a new request and click of add/delete should not update the databse. It should just add/delete a row on the form
so user logs in and can create a request that has multiple questions
finally want to submit the form and save all the information of the form in multiple tables.
As of now i a m able to have a simple form and a process that save 1 question per request.
How do i achieve this. Please assist.Do that using collections like in this example:
http://apex.oracle.com/pls/otn/f?p=31517:176
Once you are done, you may decide either to save that or to clean it up.

Hi,
I created one UDO form.
in that i am trying to fill the matrix with recordset.
becoz i am selecting the value from combobox and i run the query with this value.
so this resultant record set i want to fill in matrix rows.
oForm = SBO_Application.Forms.Item("JBWISSUES_")
oItem = oForm.Items.Item("mtx_0")
oMatrix = oItem.Specific
oColumns = oMatrix.Columns
'frm = app.Forms.ActiveForm
'oMat = frm.Items.Item("gd_act").Specific
'oMatrix.Clear()
oComboBox = oForm.Items.Item("27").Specific
ds = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
ds.DoQuery("select a.code as Code,b.Itemname as Desc1,a.quantity as Quantity from itt1 a,oitm b where a.code=b.Itemcode and a.code='" & oComboBox.Selected.Value & "'")
ds.MoveFirst()
'oColumn = oColumns.Item("col_0")
For i = 0 To ds.RecordCount - 1
oColumn.ValidValues.Add(ds.Fields.Item("Code").Value, ds.Fields.Item("Desc1").Value)
ds.MoveNext()
Next
oMatrix.AddRow()
here i am getting error like Object reference not set to instance error at oColumn.validvalues....... plz hel p me in that.
Regards,
RaviThat's because you have commented out the line where you set the oColumn object:
'oColumn = oColumns.Item("col_0")

How to delete empty row without validation error in ADF Table(EMP)
Hi Everyone,
I am using EMP Table in ADF jspx page to insert the data into database.when i insert a row into table by createInsert operation,it inserting the row.But I need to delete that row immediately with out entering any value.
But it showing some validation error at empno.Is there any ways to delete the empty row?if not,what are the reasons that we can't delete the row.
could any one tell me the reasons!!
Thanks in advance!!
With Best Regards,

Edited by: 973755 on Dec 11, 2012 6:42 AMAmar,
I am little confused with your logic here.....
but if you are trying to remove the row by clicking Remove button, you can set the immediate property to true and that remove function will run without executing any entity validation.......
