#Error cells

Hello Friends,
I am struggling #error cells in the report.The below expression is returning #error in the report and i dont understand why ?
=Sum(Fields!X.Value * Fields!Y.Value) / Sum(Fields!Y.Value) / 100
X and Y is coming as NULL from Database.In this case it should be nothing according to my understanding.

Hi altuko,
According to your description, you have an expression in a cell and it return #Error when rendering. Right?
Generally, if an expression just return #Error, it means this expression has been processed successfully. The expression is correct on logic. Mostly it has issues on the data which is passed into the expression. In this scenario, it doesn't matter if there's
null value in the data fields. As we tested in local environment, the expression will still return result.
One possibility we guess is, the data type for the two data field is not numeric. If you are running report in BI Development Studio Preview, you will get warning messages registered in the VS Output window that explain the details of why
you get #Error.
If you have any question, please feel free to ask.
Best Regards,
Simon Hou

Function to replace division by zero error cells with blank cells when calculating a numeric average

Hi everyone,
I have a five sheet spreadsheet that uses data from four sheets to calculate numeric averages in the fifth. The problem is that there is not always data in all four sheets which produces a division by zero error in the averages sheet. Is there a function or setting in Numbers 2.3 (not yet ready to upgrade to Numbers 3) that will allow these division by zero cells to be replaced by blank cells.
I have tried using statements of the form =AVERAGE(IFERROR(Sheet 1::Table 1:: B4,""),IFERROR(Sheet 2:: Table 1:: B4,""),Sheet 3:: Table 1:: B4,""), Sheet 4:: Table 1:: B4,"")). however instead of a division by zero error this produces an error telling me "the function AVERAGE expects that a number, date or duration but found "." ". It looks as though I will have to make about 400 changes to my sheet as these errors are in this and approximately 100 other cells!
I am hoping that there is some way if possible of correcting these errors without having to manually edit each cell individually.
Thanks,
Hugh

Hugh,
You may want to consider an intermediate sheet to handle the errors and then pass the result on to the main sheet.
In the following mockup, I've created a small interposing table the consists of a list of sources in column A and the result from each table. In the example, I perform some operation on those intermediate results, to be passed on to the main table. This may not be a good example, and since I don't know the overall goal of your project it's just a surrogate. (In real life we probably wouldn't be interested in finding the average of averages.)
The expression in Summary::B2 is:
=IFERROR(INDIRECT(A&"::B4"), "SourceError")

Hide Error Cell..... please help

I'm working on a spreadsheet where the data will be inputed each week.
the problem is, without the value in the field... i'm getting "Can Not Divided By Zero" error in my other fields. Once I put in a value, everything calculates correctly.
is there a way to hide this error? ignore a field if its empty? It's messing up all my formulas.... please assist

Jeff,
Yes there are ways to hide an error message. One good way is to use the IFERROR function.
For instance, in this case you could write: =IFERROR(A/B, "")
That expression translates to If A/B generates an error, display (nothing), else display A/B.

Random Cell Errors when opening Numbers Document

I recently downloaded the iWork '09 trial to see if I wanted to upgrade. When I bought iWork '08 I altered the Budget template so I could add my transactions and then have a chart which showed how well I met my budget. (Or how badly I went over)
When I opened this in the '09 version of Numbers, loads of my cells had turned into the red triangle error thing. Each one saying there was an error in the previous cell. Once I got to the first of these it just said there was an error in that cell. So I dragged the formula from the working cell above down one cell and suddenly loads of these triangle just disappeared. But at another point the triangles started again.
After ridding myself of these error cells I tried saving the file with a different name as a native '09 file. When I opened it again the error cells were back except they started in different places. After fixing saving and opening I can safely say I have a big problem, each time I reopened the document the error cells started in random places, sometimes in places where they had started previously. I saved it as a Numbers '08 file after fixing it one more time and it opened fine in Numbers '08.
I am so confused at what is going on. Am I missing something?

Have you:
- rebooted your machine?
- tried opening the same file in another user space?
- tried removing the preferences for your user to see if they are corrupt?
To remove preferences:
1) quit Numbers
2) open the folder using the Finder menu item "Go > Go to Folder…", then enter the path "~/Library/Preferences/"
3) move the files:
com.apple.iWork.Numbers.LSSharedFileList.plist
com.apple.iWork.Numbers.plist
4) start Numbers and try to open your file

Displaying Custom Error Message in ALV

Hello Experts,
Usually, when an error occurs in editable ALV, the standard WD ALV functionality marks the particular error cell in red and displays the error message.
I want the same functionality for custom error messages in event ON_DATA_CHECK. I'm able to display the message, but looking for a way to mark cells as well.
Please help....

Hello friend,
I think this link will help you much more clear on the coloring of the ALV concepts.

Error reading Excel file

Hi,

I have no idea what an "error cell" is but it's a simple text column in the spreadsheet.
Any thoughts?
Thanks in advance!
Chris

So I found the culprit.
One of the cells in the sheet had an actual value of #N/A, but not as a result of a formula.
Apparently, the XLSDataReader will interpret this as an error value.
Simply removing the # fixes this and the file is read in without any problems.
Hope this helps out others.

Error when updating xml table

Using IDCS3 I created a master table and exported as xml. Created a working ID file and copied the table over so structure was duplicated with all elements. Deleted some rows I didn't need and made some text changes in the master table.
According to the manual, when merging the tables, the source should ignore elements that are no longer there and update the text in the remaining cells.
Tried to update the xml by updating the link but get an error "Cells too small to split".
I'm new to xml so any advice would be appreciated.
Regards,
Gerry

It appears that ID can't change the cells or rows in a table, although it can change the content. The only solution is to change the table to text and modify the elements that way. The solution removes some flexibility in using tables to manage data.

Error while loading data from FDM (EPM 11.1.1.3)

Hi,
We are loading data into HFM from FDM. While loading data from FDM it is throwing an error which as below.
"Load data started: 5/20/2012 9:30:45 PM
Line 27, Error: Cell for Period Mar is not an input cell.
Actual,2011,Mar,YTD,ENT_JJ,JPY,A23232323,ENT_J76;[None];[None];[None];ICP_Load;3463437"
There were multiples lines which are throwing error.
After doing some checking we found that when we unpost ICP data in HFM we were able to load data from FDM. We have not locked the ICP entities because that will restrcit to load data. But we are not able to understand just unposting the ICP values why we are able to load data from FDM. Also we have not closed the period in HFM.
Kindly suggest, what could be the possible reason.
Thanks
Edited by: user12121146 on May 27, 2012 5:29 AM

one way to figure this out, would be to open a grad at the same POV.
It will rule out a couple things.
If it is locked, you'll visually see that it is locked. (will be grey I believe)
If it is an invalid intersection, you'll see that as well. (will be red)
If you do not have access to the cell, you will see that if you look at cell status, it will say NO ACCESS.
That should help you figure out what is happening, the quick and dirty way.

Return to the cell after data validation in JTable

Hi,
I am implementing an editable JTable. I want the focus or selection return to the current editing cell when the user inputing a wrong format data. I can catch the validation error and pop up a error message to user. But I can not return the focus or selection to the editing cell.
If anyone has already solved this problem, please give me your solution.
Thank you!
I have tried:
1.
In tableChanged(TableModelEvent e) method:
int row = e.getFirstRow();
int column = e.getColumn();
Object data = newJTable.getValueAt(row, column);
if(!validation(data)) // return true if validation OK
editFailed = true;//class variable
previousRow = row;//class variable
previousCol = column;//class variable
Add a focus listener to the table and implement the focus listener's focusLost method with:
if(validationFailed)
table.editCellAt(previousRow, previousCol);
This does move the focus to the editing cells if you want to continue to edit the table.
Problems are
If you move the focus out of the table, the wrong date will be in the table or not edited.
The selection color was shown on the next cell where you pointed your mouse to after you leave the editing cells.
2. I have also tried to use:
in the above focusLost method
table.clearSelection();
table.editCellAt(previousRow, previousCol);
table.setRowSelectionInterval(previousRow, previousRow);
table.setColumnSelectionInterval(previousCol, previousRow);
But it did not change the selection.

This is the fix for the above problem.
Basically we need to handle both mouse/keyboard actions on our own.
This code returns the control to errorCell..
/* TableCellValidator class */
/* The class basically validates the input entry in a cell and */
/* pops up a JOptionPane if its an invalid input */
/* And an OK is clicked on the JOptionPane, the control returns back */
/* to the same cell */
/* Basic Idea: The controls Arrow/Tab/mouse clicks are handled by our */
/* ----------- custom table. Its has been slightly tricky to handle */
/* mouse clicks, since when you click the next cell, the */
/* editingrow/editingcol advances. Hence the */
/* previousrow/previouscol has been captured in the */
/* setValueAt method. */
/* To capture Table/Arrow/Numeric Arrow, The keyStrokes(TAB etc)*/
/* assigned different AbstractionActions to execute like */
/* validateBeforeTabbingToNextCell */

How to load data into read only cells in HFM?

Can any one help me in loading data into Read only cells in HFM?. I am trying to lad data into a read only cell using data load file and i m getting the below error.
NB: I need the "UseLineItem Details" to be enabled.I shud be able to submit the data thoudh the "UseLineItem Details" property of the account member is enabled
Data load File
!Column_Order = Scenario, Year, Period, View, Entity, Value, Account, ICP, Custom1, Custom2, Custom3, Custom4
!DATA
Actual; 2013; January; Periodic; NZ; NZD; 141100; [ICP None]; [None]; [None]; [None]; [None]; 10000
Error Received
Line: 4, Error: Cell for Period January is not an input cell.
Actual; 2013; January; Periodic; NZ; NZD; 141100; [ICP None]; [None]; [None]; [None]; [None]; 10000
>>>>>>
Can any one please help me ....

Hi,
Example: Assume that you have Travel Account#141100
Now you have below information
Travel Expenses $30,000
Food Expenses $50,000
Hotel expenses$20,000
To enter this details normally you will create additional 3 accounts(1.TravelExpenses 2.FoodExpenses 3.HotelExpenses) under Travel Account#141100
Using lineItem Details No need to create additional accounts. you can show the detailed information in a single cell(Single Account).
To do this
1.Create a New datagrid in workspace
2.Right-click and select Cell Line Item Detail on Account#141100 (which is enabled line item details)
3.Click on add button then provide the description and Enter the amount then press enter.
1)Travel Expenses $30,000
2)Food Expenses $50,000
3)Hotel expenses$20,000
4.Total $100,000 will be shown in Account#141100
(If you want to see the detailed information just Right-click and select Cell Line Item Detail on Account#141100)
To get clear understanding please go through the HFM Admin guide.

Sarilla

Programmatically selecting a cell in a two-dimensional JTable

The problem is that when a person edits a cell and the value fails validation, I would like to programmatically select the cell. The validation is done in the setValueAt method of a Class extending the AbstractTableModel. By simply returning out of that method, the cell value is set back to the way it was before the user changed it. In addition, I would like the problem cell to be automatically selected rather than requiring the user to click in it to select it. The first question is 1- Is this possible, and 2- Any clues as to how to select it?
We find for examle in Chapter 6 of the CoreJava 2 Vol II Advanced features statements like this on page 399 of, I think, Edition 4, (can anyone tell what edition it is?) by Cay Horstmann
void setCellSelectionEnabled(boolean b)
If b is true, then individual cells are selected (when the user clicks in the cell?). I have researched this problem for several days and don't have a clue how to automatically select the cell although I know precisely what row and column it is.

This is the code to return the focus to error cell.
/* TableCellValidator class */
/* The class basically validates the input entry in a cell and */
/* pops up a JOptionPane if its an invalid input */
/* And an OK is clicked on the JOptionPane, the control returns back */
/* to the same cell */
/* Basic Idea: The controls Arrow/Tab/mouse clicks are handled by our */
/* ----------- custom table. Its has been slightly tricky to handle */
/* mouse clicks, since when you click the next cell, the */
/* editingrow/editingcol advances. Hence the */
/* previousrow/previouscol has been captured in the */
/* setValueAt method. */
/* To capture Table/Arrow/Numeric Arrow, The keyStrokes(TAB etc)*/
/* assigned different AbstractionActions to execute like */
/* validateBeforeTabbingToNextCell */

Reporting one message-text for several errors

hy,
I have a table binded to context. The table hase several rows and columns. The user can edit the values in table-cells. Now I want to make a plausibility-check for all values in the table. And if there are for example 5 errors I want to mark the error-cells red. Therefore I wrote
msgMgr.reportContextAttributeMessage(
 element,
 attrinfo,
 IMessageZABComp.TEST,
 new Object[] ,
 false
for every error-field. My problem is that there are 5 error-messages shown in the message-area, but I want to show only one error-message "please correct your input !". How can I do this ? How can I put out only one message in the message-area, though there are several errors ?
Florian

hi florian ,
can you elaborate on the situation. if you define any message inside the message pool and display it using
Msgmngr.reportcontextattributeMessage(elemnt,attributeinfo,IMessage<compname>.test,new Object [] ,false) , it'll only display the error message with id 'test' only once. just check if you are writing this code inside a loop.
regards,
rahul.

ALV Grid: Problem with errors

Hi,
Many of you must have definitely experienced this problem.
I have some default rows on ALV screen for user to enter data.
Say field1, field2 are in the fields list. Now if user puts values in field2, I consider that as a change and I validate entire row. Say field1 is mandatory. I show an error on field1 when field2 has been changed by adding protocol entry.
Now if user changes different row and presses enter, mod_cells does not contain entries related to field1 for first row even though protocol contains errors for field1 on first row. Because of this, first row is not getting validated again.
I added adding an entry in mod_cells for field1. It does not seem to work.
Please let me know if you have any solution for this problem.
Thanks.
Srinivas.

Hi Aaron,
set_selected_cells or so is the method. then user is positioned at the error cell.
regards,
Clemens

Your $reqfields array doesn't contain streetaddress. It uses address instead. That's what's causing the problem. You would be able to detect this type of issue yourself if you configured PHP to display notices in addition to other error messages.

Problem while tabbing out of a cell

I have a JTable in which if I enter an invalid data in a particular cell and tab out, after showing the error message the cursor should be brought back to the error cell. I was able to do this with the following code.
isCellEditable(int row, int col){
tblDamageDetials.changeSelection(errorRow,errorCol,false,false);
tblDamageDetials.setEditingColumn(errorCol);
errorRow and errorCol will have the row and col where the invalid data is present.
This will act like a lock and will never let u out of the error cell if u tab again. But I want the error message to appear everytime I tab out of the error cell.
The code to display the error message is invoked from the method setValueAt().
But the problem is when I try to tab out of the cell again, I'll not be getting the error message again.This is because the setValueAt method will be called only if the cursor is on the celleditor. But the above code will not put the cursor on the editor, instead it will be on the renderer only. So while tabbing the setValueAt will not be invoked.
I tried bringing the focus to the editor by using tblDamageDetials.editCellAt(erroRow,errorCol);
Then I am getting StackOverFlow error.
Could somebody please help me out.

Thanks for the help.I tried implementing what u told, but still I'm getting StackOverflow exception.I'm getting the exception at editCellAt() method.
I'll paste my code here.If possible please look into it.
