How to display the last value of a field in a group in the group header

I need to display the last quiz score from a group of quiz scores as part of the header of a group of units (the quiz score values are in the detail record). I can not use the group footer, which would be the natural place to find the last value. It must be in the group header because there will be a subsequent group within the unit group. In other words, the grouping is as follows:
Unit Group Header (Display last quiz score in unit)
SubUnit Group Header (Display other detail summaries)
Detail Record (including quiz score)
SubUnit Group Footer
Unit Group Footer
While there is a minimum/maximum summary function, there is not a first/last function.

Hi Fuskie,
One suggestion to display the last quiz score in the Group Header, other than what had already been suggested, will be to use a linked subreport in the Group Header. It is not an efficient way to display the information, but it could do the trick.
Another suggestion will be to insert a subreport in the report header, then store the last quiz score in an array for each group, then share it with the main report and display the values in the appropriate group. In this way it will only connect twice to the data source, one for the main report and once for the subreport, instead of multiple connection for each group.
Finally, the most efficient way will be to have this value calculated on the database side using a command object or a stored procedure.

Get the Last Value of Status Field from SQL TABLE using SQL 2008

I have a table with Fields such as
UploadstartTime, UploadEndtime, STATUS From TBLA.
The STATUS Field, has values =7 and 11 are failed and 12 is SUCCESS. I cannot do a max, since it will always show 12, I need to get the MAX(UPLOADENDTIME, and get STATUS For that record. How can I do that using 1 SQL Query?
My current code is: The issue is
select
TBLNAME
MaxUploadstarttime
=
max(UploadStartTime),
MaxUploadEndtime
=
max(UpLoadEndTime),
Status=max(status)
from DB.DBO.LOGTABLE

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. You failed! Temporal
data should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> I have a table with Fields such as <<
Fields are not columns! There is no generic status in RDBMS. Putting “tbl-” in a table name is called tibbling and we make fun of people who do it (Google Phil Factor's humor columns. If you were polite is this what you wanted to post?
CREATE TABLE Something_Uploads

PRIMARY KEY (upload_source_name, upload_start_timestamp),
upload_end_timestamp DATETIME2(0),
CHECK(upload_start_timestamp < upload_end_timestamp),
upload_status INTEGER NOT NULL

How can I just display the selected value of a listbox in a report without the reverse display and selection buttons?

I am using a table which contains a text field with a lookup. I want to use the selected value of this field in a form which is acting as a selection form. No editing of the field's value is permitted. How do I just display the value of the field (which
is considered a listbox on the form) without the reverse display and the up and down selection buttons.
I can provide an illustration of the condition I am trying to overcome, but this system doesn't accept it.
Thank you for any suggestions or clarification you can provide.
Marj Weir

Thank you. I'll try that approach.
I found, after much experimentation, on a similar problem involving a multiselect lookup field, that if I make the field invisible, and add a textbox that displays the fieldname plus .column(0), it displays all the selected entries.
E.g.: staff.Column(0)
Staff is the field containing the last names of selected staff members.
staff.Value only shows the first name in the lookup list whether it is checked or not, so this is useless.
staff.column(0), however, (inexplicably) shows all the selected names, e.g. Jones, Smith, Wiggins.

How can I reference the last value in a column?

How can I reference the last value in a column? For example, today I want the value of A1 to appear in another cell. Tomorrow, I will add a row and want to reference A2, next day A3, and so forth.

Now I got it:
=OFFSET(A1,COUNT(A)-1,0)

WAD - display only the last value in the chart

hi...
I designed a chart in WAD wich displayed a range of values in a line. Now im searching for a possibility to display the value for the points in my chart, but not for all values, only for the last value in the line! And every month the line will extended with new value-points, so it is necassary that the function is dynamic, always for the last point in the chart the value should displayed!?
thx for some ideas!
david

hi @ all... once more information:
the chart displayed only one keyfigure of a query. for example it display the revenue per month. in jan. = 10, feb. = 15, mar. = 25, apr. = 13, jun. = 23. these values should be displayed in a line in the chart aaaand additional for the last one in the line the valuecaption direct in the chart (f.e.: jun. = 23). not for all "periods-points"only for the last one.
in jul. = 25 the chart changed and only for july the value-caption should be displayed. Is it possible?

David

How to determine the "Last Value" in exception aggregation

Hi gurus,
I have a KeyFigure with an exception aggregation -Last value- by time.
I report on a multiprovider ("containing" a infocube and a realtime infocube with BPS-InputLayout). I can correct separate Items with this BPS-Layout. So, at the end I have 2 values for one item.
So, by these facts, my report shows the the last value for the specific KeyFigure, but I expected that both values (the value in the infocube and the correction via BPS)are sumed up.
As this is due to the exception aggregation not the case, I could "overwrite" the normal value in the infocube with the BPS.
But SAP determines the normal value in the Infocube as "Last Value", not the one in the correction cube, which is entered via BPS.
How does SAP determine the "last value" as I can´t see any date...
Thanks in advance!

Thank you for your answer...
I got the soltion by myself.
I thought, Last Value means the last Value, depending on the time, but in my opinion the function last value should be called "Greatest Value".
All figures with the same value for the reference characteristc are aggregated anyway.

How to pick up the last value of the input string

Hi there,
I have a requirement in which I have to pick up the last value of the input string.
I don't know the field length, it could be 10 line, it could be 4 line and it could be even 1 line.
Another problem is that the field contains all the alphanumeric values so the sort function is not working.
I believe I need to write a UDF but not sure exact what and how.
Can some body please help me solving this issue.
Input.
1.Abc
2.abc123atxx.com
3.(980)771-2341
4.
5.518VR50V58AD10DSAYBDSAFDSIEGHA:1
In that case I only need to pickup the last value i.e. 518VR50V58AD10DSAYBDSAFDSIEGHA:1
Output
518VR50V58AD10DSAYBDSAFDSIEGHA:1
Note:
1. Length is unknown
2. Alphanumeric data
Thanks,

Hi karthick Lakkar,
Thanks for your quick response but unfortunately I am getting mapping exception.
What I did is create a UDF with 2 input
INPUT
a string
b string
and then this code
int Length=Integer.parseInt(a);
int requiredLength=Integer.parseInt(b);
if(Length<=requiredLength)
return(a);
else
return a.substring((Length-requiredLength),Length);
I am wondering about the input as well.
At present I am doing
KTEXT + KTEXT --- UDF
+ does represent concat, means same input will go to the UDF
This is the error which I am getting
Exception:[java.lang.NumberFormatException: For input string: "Kevin Farrar"] in class com.sap.xi.tf._MM_XXXXXXXXXXXXXX_ method calculate[Kevin Farrar, Kevin Farrar, com.sap.aii.mappingtool.tf7.rt.Context@6dbf19db]

How to get the last value edited by users from JTable?

Hi.
I have a JDialog that includes an editable JTable. This table is used to set up field caption and font for a report program. I found only when cursor is moved to another cell, the value in current cell being edited will be transferred to Table Model. So if the user don�t move cursor to another cell after editing the value of a cell but click OK button directly, Table Model cannot get the last value edited by the user, I wonder if there is a way to fire JTable to transfer the value being edited to Table model.
By the way, I found if the TableCellEditor is using JCheckBox or JComboBox instead of JTextField, there is no this problem.
Thank you for any reply.

I guess you can make use of the following methods on your table model to inform it make it getValueAt bcos table data has changed.
fireTableCellUpdated
Notifies all listeners that the value of the cell at [row, column] has been updated.
fireTableChanged
Forwards the given notification event to all TableModelListeners that registered themselves as listeners for this table model.
fireTableDataChanged
Notifies all listeners that all cell values in the table's rows may have changed. The number of rows may also have changed and the JTable should redraw the table from scratch. The structure of the table (as in the order of the columns) is assumed to be the same.
But when to call these methods??
-- When OK button is pressed, do this as the first thing!!
OR
-- Call this on every key event!!

JTable problem : how to get the last value entered by user + event lost

Hi all,
I have 2 problems with Jtable class.
1 => To get the last value entered by user in a cell,
it seems that we must change the selected cell.
That is to say we can only have the previous cell's value.
Is there a simple way to get the current value of any cell ?
2 => To resolve the problem i store the values of each cell in a vector and i intercept keyboard event (!)
BUT, when i do a double click with the mouse on the Jtable, i loose keyboard events. Then, i can't intercept them.
Is it a bug of swing or am i following a wrong way ?
Thanks by anticipation for your help.

You have to fire the "TableCellUpdatedEvent"
and override the getCellEditorValue in TableCellEditor to return the current value

How to get --Last date of the Last value .

Dear All,
I have a report like
Material Country Current Price
1112----- Singapore -
100
1112----- Japan -
120
1112----- Malesia -
99
Here current price is Last Value of the particular Material on particular Date.
This I can get based on Key figure Aggregation ( Last Value and reference Character 0CALDAY ), It is giving the last Value of the Particular Material.
Now my user wants to see Last date of the value ( Date of the Value )
Example :-
Material Country Date --Current Price
1112----- Singapore -
01/04/2008 -- 100
1112----- Japan -
04/05/2008 -- 120
1112----- Malesia -
05/05/2008 -- 99
If I drill down the date in my report it is showing all dates , my user wants to see only last date .
Hope some one has solved this issue , please help me to solve this issue.
Regards,
SHAIK.

I have created a keyfigure with date as a data type.
In aggregation tab, I selected aggregation Maximum.
Upto DSO, data is Loaded perfect. Ok.
I added the same key figure in cube , When I am trying to Activate the Transformation,
It is giving Error message.
Rule 17 is invalid and is being deleted. The reason for this is that a field or InfoObject that is used in rule 17 has been deleted in the source or target of the transformation ODSO ZPL_DSO1 -> CUBE ZPLATT_C (0GH6MHANQ2J79LXZBLGIJ9ZK9LWHK6RS)
Plz Advice.

How to display first row value returened from a query as checked as default in a report

How to display first row value returned from a query as checked as default in a report
Example
Parameter 1
Paramerter2

Mudassar

Hi Mudassar,
The issue is caused by the order in which the parameters appear in the report data tab can be difference between our report execution and it failing. In other words, “Parameter2” is execution before parameter “A” due to this issue. We can adjust the parameter’s
order to solve the issue.
If “Parameter2” is parameter “A”, we cannot use that expression. Because fields cannot be used in report parameter expression, if we want to display the first value returned from a query as default value, we have to fill the “Specify values” text box with
the specific value in Default Values dialog box.

How to check the whole values of a set of map exist in the vector of map?

Hi Friends!
I have a set of map; map<int, set<int>>myset;
and a vector of map; map<int,vector<int>>myvec;
myset contains;
1=>11 16 30
3=>2 11
6=>2
7=>9 12 16
8=>9 13 16
myvec contains;
1=>11 15 21
2=>16
3=>11 16
4=>2 13
5=>11 16 30
6=>9 5 10
First, the first value of myset(11 16 30) will be checked with all the values of myvec, if the whole value(11 16 30) available at certain value in the myset, then it gives the key of myvec. So, the output for the first value is 5.
Next, if you consider the value (2 11) in the myset, there are no matching values that contains whole 2 11 in the particular value in myvec. Therefore, what we do is, delete the last value of the current set, that is 11, and now consider 2 as
the value and find the matching value from myvec. That is (2 13) and the key is 4.
Like wise when we find the first possible match, then we print the key of myset immediately, there may be some other possible values available in the values of myset.
I have written two functions that check the particular whole values of the myset matched with a particular values in myvec.
bool IsValueInVec(int value, const IntVec& v2)
IntVec::const_iterator itv=find (v2.begin(), v2.end(), value);
if (itv!=v2.end())
return true;
return false;
bool AreAllValuesInVec(const IntSet& s1, const IntVec& v2)
for(set<int>::const_iterator sit=s1.begin();sit!=s1.end();++sit)
if (!IsValueInVec((*sit), v2))
return false;
return true;
Could anyone help me to solve this?

You have neither a set of map nor a vector of map. You have two maps. Each contains keys of type int. The mapped values of one are of type set<int>. The mapped values of the other are of type vector<int>. If
you don't understand the types of the objects you are using, you will never be able to use them properly.
Help you solve what? Do the two functions you wrote perform as desired? If not, provide a complete description of how what they do differs from what you want.
Somewhere in code you have not shown, you need to call AreAllValuesInVec for a particular set and vector. If this function returns false and if the set contains more than one element, you need to delete the last element of the set and try again.
If the set contains only a single element, you need to perform some "failure" processing that you have not described. When the function returns true, you need to print the key of the map element which contains the vector. What are you
having trouble with?

How to Check the total value of a field

Hi,
I want to check the total value of a field (this total is obtain by using property of that field thru personalization).
that means , in a table 3 columns are there (col 1, col2 & col3). I personalized the total property as true for col3.
now i'm getting the total for that field.
I want to check that total whether it crossed 100 or not.
How to do this?
Thanks in advance,
SAN

Hi San,
You can achieve by using OATotalRowBean, search for OATotalRowBean in this forum you should be able to get some sample code.
public class OATotalRowBean
extends TotalRowBean
implements OAWebBean, OAWebBeanConstants
A special row rendered at the bottom of a table which lets users see totals for columns which are designated for summing.
Note The total is calculated and displayed only for visible rows.
When you indicate that you want to total one or more columns, the OA Framework creates an OATotalRowBean and designates it as the columnFooter named child of the OATableBean. If the OATableBean is also configured to insert rows (so it has an "Add Another Row" button), then the total bean becomes an indexed child of the add table row bean (see OAAddTableRowBean), which the OA Framework in turn designates as the table's columnFooter object.
If you need to access the table's column footer object for any reason, call the OATableBean's getColumnFooter() method. If row insertions are enabled, this method returns an OAAddTableRowBean; otherwise it returns an OATableRowBean.
For detailed information about creating and working with tables, see OA Framework Developer Guide: Tables.
With regards,
Kali.

Under Network Preferences, select the WiFi
click on "Advanced..." button
Select the network you want to delete from the list and click on "-"
Click "Ok"
Click "Apply"
Well done ;-)
You may also want to delete the wireless key from Keychain.
