I need to create a report that displays an empty ALV with 4 columns and that is editable (the user can input on the fields of the ALV).
The ALV is going to be used as an input for the user and the data is then going to be read from the ALV.
What would be the best approach for this?
When youre setting the fieldcatalog, you need to declare "editable". For example
wa_fieldcat-fieldname = 'REMARKS'.
wa_fieldcat-scrtext_m = 'Purchase Order'.
wa_fieldcat-col_pos = 1.
wa_fieldcat-outputlen = 10.
wa_fieldcat-editable = 'X'.
wa_fieldcat-key = 'X'.
APPEND wa_fieldcat TO it_fieldcat.
CLEAR wa_fieldcat.
Then you need to declare in your process after input(PAI) the check changed data of the alv.
alv->checked_changed_data

I have just created a window, containing a fill-in field (TestField) and a checkbox (chk_TestField):
DEFINE VARIABLE TestField AS INTEGER VIEW-AS FILL-IN.
DEFINE VARIABLE chk_TestField AS LOGICAL VIEW_AS TOGGLE-BOX.
It is very simple to change the value of the fill-in field, based on the checking of the checkbox, something like:
ON VALUE-CHANGED OF chk_TestField IN FRAME DEFAULT-FRAME
DO:
TestField = 5.
END.
However, I'm interested in changing an attribute of the Fill-in field itself, not the integer it represents (I would like to make the fill-in field read-only), how to I do this?
I've tried:
ON VALUE-CHANGED OF chk_TestField IN FRAME DEFAULT-FRAME
DO:
TestField.Read-Only = NOT(chk_TestField).
END.
This, obviously, does not work.
ASSIGN TestField:READ-ONLY IN FRAME {&FRAME-NAME} = TRUE.
or
ASSIGN Table.TestField:READ-ONLY IN FRAME {&FRAME-NAME} = TRUE.

How Can make this happen:I want that on click of the button to show the table.Please the code to be as simple as possible and as easy to understand as possible.if you can't make it with a button make it with a radiobutton or smth else.
Thanks in advance!
If you want to keep it simple, you can use "sy-ucomm" which stores your last triggered action. With your button, it'd look like this:
AT SELECTION-SCREEN.
CASE sy-ucomm.
WHEN 'PRESS'.
*code for displaying your table via ALV or WRITE goes here*
ENDCASE.
The most common way to display internal tables like this is with an ALV, a simple example of how to build up an ALV can be found here:
https://archive.sap.com/discussions/thread/873601
If you'd like it to do the WRITE: to screen under one circumstance, and display the ALV Grid in another, you should use Select Options and parameters.
Your code needs the addition of EVENTS, please take a look here on what they are and how to use them:

I can successfully retrieve data from my mongoDB instance but need to re-use the objectID for a depending query.
The following code seems to get my entire object but NOT the id. What am I missing?
# Perform a query and retrieve data
mongoOBj <- m$find('{"em": "test#test.com"}')
I realise this is an old question and OP has probably figured it out by now, but I think the answer should be
mongoOBj <- m$find(query = '{"em": "test#test.com"}', field = '{}')
instead of
mongoOBj <- m$find(query = '{"em": "test#test.com"}', field = '{"_id": 1}')
In the second case, the result will be a data frame containing ONLY the IDs. The first line will result in a data frame containing the queried data, including the IDs.
By default, field = '{"_id": 0}', meaning _id is not part of the output.
If you look at the documentation you see that the find method takes a field argument, where you specify the fields you want:
find(query = ’{}’, fields = ’{"_id" : 0}’, sort = ’{}’, skip = 0, limit = 0, handler = NULL, pagesize = NULL)
So in your case it will be something like
mongoOBj <- m$find(query = '{"em": "test#test.com"}', field = '{"_id": 1}')
FYI So the easiest way to get all fields is to do the query with field="{}". That will overwrite the default in the mongolite:: package find() arguments list.
It was driving me nuts for a little while too.
LATEST UPDATE: Issue answered here. Some one else at stackoverflow had a similar issue and it was resolved. Solution provided for convenience. This is the line of code I was missing:
comboHeaderColumn.useLabelFunctionForFilterCompare = true;
that line is followed by these:
comboHeaderColumn.filterComboBoxBuildFromGrid = true;
comboHeaderColumn.labelFunction = formatState;
where formatState is a local method that formats the data for the combobox.
UPDATE: I've now got the combobox's loading with the correct data, but when I select a value nothing happens. The combo boxes load only data that is in the column, and when you select a value in the combobox, it's supposed to filter the rows on that value. It doesn't.
Thanks for looking. I'm having trouble getting multiple filters to work in Flex in Flash Builder 4 using the ExtendedDataGrid and ComboBox's. Here is an image of part of the grid:
The User Name and City filter properly if you type text into the box's above the column header and the Request Date lets you select date ranges if you click on the Custom bar, but the Request Reason and State ComboBoxes do not list anything. I've created them using comboHeaderColumn.filterComboBoxBuildFromGrid = true; but all it does is put "[object Object]" as the only other selection under All.
I've used this article but it will only allow you to use a single filter for the entire grid.
My finished grid will have about 20 columns and from 20,000 to 450,000 rows of data so the filters are really important and I'll need more than one.
The code is very straight forward and loops through all the returned data and if the column is identified as a filter column it does this:
comboHeaderColumn.filterComboBoxDataProvider = codeValuePairs;
comboHeaderColumn.filterComboBoxLabelField = "Value";
comboHeaderColumn.filterControl = "ComboBox";
comboHeaderColumn.filterOperation = FilterExpression.FILTER_OPERATION_TYPE_EQUALS;
comboHeaderColumn.headerText = ac.Header;
comboHeaderColumn.dataField = ac.Name;
if( ac.Header == "State" || ac.Header == "Request Reason" )
{
comboHeaderColumn.filterComboBoxBuildFromGrid = true;
}
ProfileDataColumns.push(comboHeaderColumn);
This creates 2 entries in the combo box: All and [object Object]
What am I missing??? Anyway, after half a day searching I decided to reach out.
Any suggestions or direction to an article would be very much appreciated.
Thanks.
I'm creating a table that displays information from a MySQL database, I'm using foreignkeys all over the place to cross-reference data.
Basically I have a datagrid with a column named 'system.' The system is an int that represents the id of an object in another table. I've used lableFunction to cross-reference the two and rename the column. But now sorting doesn't work, I understand that you have to create a custom sorting function. I have tried cross-referencing the two tables again, but that takes ~30sec to sort 1200 rows. Now I'm just clueless as to what I should try next.
Is there any way to access the columns field label inside the sort function?
public function order(a:Object,b:Object):int
{
var v1:String = a.sys;
var v2:String = b.sys;
if ( v1 < v2 ){
trace(-1);
return -1;
}else if ( v1 > v2 ){
trace(1);
return 1;
}else {
trace(0);
return 0;
}
}
One way to handle this is to go through the objects you received and add the label as a property on each of them based on the cross-referenced id. Then you can specify your label property to display in your data grid column instead of using a label function. That way you would get sorting as you'd expect rather than having to create your own sort function.
The way that DataGrids, and other list based classes work is by using itemRenderers. Renderers are only created for the data that is shown on screen. In most cases there is a lot more data in your dataProvider than what is seen on screen.
Trying to sort your data based on something displayed by the dataGrid will most likely not give you the results you want.
But, there is no reason you can't call the same label function on your data objects in the sortFunction.
One way is to use the itemToLabel function of the dataGrid:
var v1:String = dataGrid.itemToLabel(a);
var v2:String = dataGrid.itemToLabel(b);
A second way is to just call the labelFunction explicitly:
var v1:String = labelFunction(a);
var v2:String = = labelFunction(b);
In my experience I have found sorting to be extremely quick, however you're recordset is slightly larger than what I usually load in memory at a single time.
