Wda date picker issue in alv table

Hi,
When I use a date picker in a alv table in wda I have got the following issue:
Select a date, do not press enter and then press a search help in another field in the table. You can test this in web dynpro 'SALV_WD_DEMO_TABLE_F4'.
When you do this you will see that when pressing a search help like the one of 'currency' the date that you previously selected is gone. Also since on_data_check is not triggered in this scenario I am not sure how to solve this. My guess is that it is a bug. Maybe it can be resolved with an on_click event. That way I can update the date field when a select the currency field (before pressing f4 in the currency field)
Does anybody know if this is the best way to solve this?

Hi Raymond,
What you mentions is Correct and What your are doing is correct. It is bug in WD ALV. It's not checking the value after you given correct value.
Thanks and Regards,

Sorting Issue in ALV table

Hi,
I have included a ALV table in my application. A column in the table is containing a list of amounts. When i am trying to sort it in ascending or descending order, the values are not listed properly. I am using "PAD_AMT7S" as the data type for the attribute which will accept up to 2 decimals. The issue is,
if the column is containing values like
0.00,
8.75,
17.00,
8.50 and
17.50.
if i perform ascending type of sorting the values are re-arranged as,
0.00
17.00
17.50
8.50
8.75
and on descending
8.75
8.50
17.50
17.00
0.00
Which are all incorrect. Please provide me your suggestions..
Thanks,
Mugundhan

Hi,
Are you using the IF_WD_TABLE_METHOD_HNDL for the sort, or you wrote your own code?
IF_WD_TABLE_METHOD_HNDL worked incorrectly for some special fields, in these cases I had to write the sorting code manually.
e.g.
CALL METHOD WDEVENT->GET_STRING
   EXPORTING
     NAME   = 'COL'
   RECEIVING
     VALUE = lv_col_name.
CALL METHOD WDEVENT->GET_STRING
   EXPORTING
     NAME   = 'DIRECTION'
   RECEIVING
     VALUE = lv_direction.
CASE lv_col_name.
    WHEN 'TABLE_FIELD1'.
      IF lv_direction EQ '00'.
        SORT lt_table BY CURR ASCENDING.
        ELSE.
          SORT lt_table BY CURR DESCENDING .
      ENDIF.
Is the table sorted incorrectly here?

Hi Zafar,
You can populate your internal table as per the requirement.
at new order only.
itab-Order = 3000000 .
itab-Order quantity = 100.
append itab
for all materials for that order
itab-MATERIAL       =   610 .
itab-TOTAL QTY = 100 .
itab-SHORTAGE QTY = 5.
append itab.

Regarding custom currency data element issue in custom Table.....

Hello,
I am currently working on creation of a Z custom table in SAP. There is data coming from
mainframe for amount field in the form -9999.9999.
To store data like this I am creating a custom Z data element with Z domain definition as follows:
Data type; Curr
No of characters: 5
Decimal places: 4
Sign box is checked.
Now when I use this Z data elemnt for a firle in custom table, while activating, it asks for table refernce and table field. What do I give it here ?
Please help.
Regards,
Jainam..

Hi Jainam,
very basic ABAP knowledge: A field of type CURR isn used to store a currency amount. Every currency field must be connected to a currency key of type CUKY.
The same concept applies for quantities and units.
You can spare a lot of trouble if you look at standard tables and programs, copy or use data elements and/or structures from standard.
If you want to re-invent the world, you may need more than seven days.

Page title duplicating in the grid ALV table header when run on portal

Hi Experts,
I am facing an issue with the ALV display. My object contains three screens.
The first screen is a selection screen.
The second one is an overview screen which displays the data in a Grid ALV table corresponding to the "supplier id" entered in the first screen.
The grid ALV has a header(contains name,location etc) and a table to display data.
I have created a SAP Transaction iView on the portal for this object.
The issue here is that when I run this in ABAP, everything is fine.
But when I preview it on the portal, the first screen is displayed correctly but in the second screen the title of the page is duplicated in the table header and the header that is supposed to display the name, location etc. is replaced by the duplicated title.
Please suggest an alternative or solution for this.
Thanks and Regards,

How to change font while displaying data through an ALV table in WDA?

Hi all,
I am displaying data through and ALV table. Now I want to change the FONT only for few rows. Is this possible?
If so then do the needful to me..
Thanks & Regards,
Yugesh A.

I believe as you have found 'LVC_FIELDCATALOG_MERGE' would only work with the classic dynpro (SAPGUI based) version of the ALV.
You won't be able to control the font the same way in the WDA version of the ALV. You will need to create a custom cell editor for the column(s) in question. You can then bind context attributes to the properties of the cell editor. You will need extra attributes in your bound context to control these settings on the row level. Also you will be restricted by the changing the DESIGN property. This means only the values allowed for the DESIGN of the particluar UI element. For a TextView that wouldn't be the font directly (the font of course comes from the Theme).
DATA l_salv_wd_table TYPE REF TO iwci_salv_wd_table.
l_salv_wd_table = wd_this->wd_cpifc_alv_adv( ).
DATA l_table TYPE REF TO cl_salv_wd_config_table.
l_table = l_salv_wd_table->get_model( ).
data textview type ref to CL_SALV_WD_UIE_TEXT_VIEW.
l_column = l_table->if_salv_wd_column_settings~get_column( 'ADD_PARTICIPANTS' ).
create object textview.
textview->SET_TEXT_FIELDNAME( 'ADD_PARTICIPANTS' ).
textview->set_design_fieldname( 'ADD_DESIGN' ).

l_column->set_cell_editor( textview ).
DESIGN supports the following options:

This enumeration value is deprecated. Instead, use SectionHeader.

Text is highlighted with font size +5.08 cm relation to the default font size.
header3
Text is highlighted in default size
header4
Text is highlighted in font size -1 (small) in relation to the default font size (like the legend but highlighted)
label
Text is display in the default font type. A space is always inserted after the text.
label_small
Text is displayed in default font type, as with label, onyl that font size is -1 (like the font size for header4).
legend
Text is displayed with default font type in size -1.

Text is in italics and in default font size.
standard
Text is displayed in default font size. No text attributes are defined for this value.

Text is displayed in no-proportional font type. Each letter takes up the same space.

How to display different icon within WDA alv table base on row data ?

Hi,
is that possible to display different icon for every row within ALV table depending on the row data ?
for instance if the status 'S' display ~Icon/SuccessMessage and 'E' display ~Icon/ErrorMessage ?
because base on this code below i only can set 1 icon for the whole row data.
LOOP AT lt_columns ASSIGNING <fs_column>.
    CASE <fs_column>-id.
      WHEN 'ICO'.
        CREATE OBJECT lr_caption.
           lr_caption->set_image_source( value = '~Icon/SuccessMessage').
           <fs_column>-r_column->set_cell_editor( lr_caption ).
    ENDCASE.
ENDLOOP.
Thank you in advance.
Fernand

Hello,
Yes it is possible to display different images based on data.
For that what you can do is create one attribute 'STATUS' of type string in context node which you are mapping to ALV.
And fill that attribute with the path to image based on your requirement like for status 'S' set the attribute to ~Icon/SuccessMessage and if status is 'E', set it to ~Icon/ErrorMessage at runtime.
Now in the settings for ALV use the following code:
* Display icon in column seatsocc
DATA: lr_column TYPE REF TO cl_salv_wd_column,
        lr_image TYPE REF TO cl_salv_wd_uie_image,
        lv_icon TYPE string.
lr_column = lv_model->if_salv_wd_column_settings~get_column( 'SEATSOCC' ).
CREATE OBJECT lr_image.
lr_image->SET_SOURCE_FIELDNAME( 'STATUS' ).
lr_column->set_cell_editor( lr_image ).
in the above code, column 'SEATSOCC' will be displayed as an icon.
Sample code to fill the attribute 'STATUS'
LOOP AT lt_flights INTO ls_flight.
    lv_seatsfree = ls_flight-seatsmax - ls_flight-seatsocc.
    IF lv_seatsfree = 0.
      ls_flight-status = 'ICON_RED_LIGHT'.
    ELSEIF lv_seatsfree <= 50.
      ls_flight-status = 'ICON_YELLOW_LIGHT'.
    ELSE.
      ls_flight-status = 'ICON_GREEN_LIGHT'.
    ENDIF.
    MODIFY lt_flights FROM ls_flight.
ENDLOOP.
Hope this helps!

In webdynpro for ABAP alv table issue

hello gurus,
                  i am new for webdynpro for ABAP.i strucked at one point at designing time.anybody could you suggest me on this.
thanks in advance.
let me explain my scenario first.
in my webdynpro for ABAP developement i have one alv table having ten fields.i am featching the data for eight fields from one Ztabale and updating , for rest of two fields we need to fill after displaying output using the respective F4 help. Right now these two fields are in input editable mode.now i am getting the values successfully from F4 help and at the same time it is allowing MANUAL ENTRIES also but as per my requirement it should not allow any manual entries . for this i have made these two fields are in readonly mode as like as rest of fields to avoid the MANUAL ENTRIES but at this time i didnot get any F4 helpfor those two fields.
so how can i achive my goal in this thing could any one suggest me.
my final conclusion is we need to get only F4 help values into those two fields . it should not allow any manual values at any point of time.

Thanks in advance.
Regards,
Subba Reddy.

Hi,
You can create Button in your ALV table column with below code
DATA lo_button              TYPE REF TO cl_salv_wd_uie_button.
CREATE OBJECT lo_button.
    CALL METHOD lv_value->if_salv_wd_column_settings~get_column
      EXPORTING
        id    = <your column name>
      RECEIVING
        value = lo_system_select_hdr.
    lo_button->set_enabled( value = abap_true ).
   lo_button->set_text( value = 'Avaliable List' ).
    lo_button->set_tooltip( value = 'Avaliable List' ).
    lo_system_select_hdr->set_cell_editor( value = lo_button ).
And for button click action,
Create a method (say SHOW_DATA( ) ) with on_click event handler.And when you click button on your ALV table, SHOW_DATA( ) method will trigger.
Thanks

Apex 3.1 Upgrade Issue - dba_lock and date picker display

A couple of minor issues I've seen with my upgrade from 3.0.1 to 3.1. Just wondered if anyone else has seen them and if anyone has a simple fix for the date picker problem :
1. DBA_LOCK - the upgrade process itself complains about the SYS.DBA_LOCK view not existing - easily remedied by running catblock.sql before you start the upgrade (but not listed as a pre-req)
2. DATE PICKER display - I have a date picker item in a navigation region - before the upgrade the calendar icon happily appeared directly to the right of the date cell, since the upgrade the icon has moved to underneath the cell, messing up the look and feel. (Also the size of the pop up calendar doesn't quite fit its contents now and you have to resize to see the close and ok buttons )
Any confirmation that others can replicate the second issue or a quick fix would be very helpful.
Many thanks,
Rich.

Rich,
>> Unfortunate that something has changed between 3.0 and 3.1 then that will require us to change the formatting. Hopefully not too much work to sort out a form region that looks the same though.
I know the templates were revised for APEX 3.1, but that should not have affected existing applications. So you're saying that application used a Navigation Template before just fine without issues? I'll ask Carl to investigate.
>> The issue of the default size of the pop up window cutting off the buttons at the bottom still remains in your example however. (obviously users can resize it but not ideal)
Well, that really sucks. The worst thing we can do is break the behavior of existing applications, and it appears we've done it here. I filed Bug 6864371 on this issue. We'll get it fixed in the very first patch set for APEX 3.1.

WDABAP - How to read data from filtered ALV table

HI
In Web Dynpro for ABAP.
I have a view with an ALV table on it.
I would like to know how to read the data that's been filtered in the ALV table?
Regards

I've managed to find out that during runtime the following code returns a reference to a class pool:
data: lr_salv_wd_table TYPE REF TO iwci_salv_wd_table.
lr_salv_wd_table = wd_This->wd_cpIfc_ALV_GRAPHICS_DATA( )
Two of the attributes of this class pool are:
<b>IG_COMPONENTCONTROLLER~R_COMPONENT = </b>
<b> IF_COMPONENTCONTROLLER~R_COMPONENT = </b>
The attributes, IG_COMPONENTCONTROLLERR_COMPONENT and IF_COMPONENTCONTROLLERR_COMPONENT references a class CL_SALV_WD_C_TABLE. This class has an attribute R_RESULT_DATA which references a class CL_SALV_WD_RESULT_DATA_TABLE. The attribute T_RESULT_DATA contains the filtered data.
Now I need to find out how I can access these attributes in the view.
Regards

VA01: Align Good issue dates existing on Schedule line table.

Hi Experts,
     I will exemplify my question in order to make easier to understand it. I have a sales order with two lines. Both lines will have different routes determination due to those products have different classification (the first is non-dangerous and second on is dangerous). Dangerous items will have more transit time to get the customer than non-dangerous items. When we have different routes per line items in the sales order, the system will calculate schedule line dates (good issue date, material availability date) differently. However, what the Business wants is to deliver the goods at the same good issue date (VBEP-WADAT). So to get this approach we will have to:
- Check field complete delivery indicator).
- Set the route for non-dangerous good as same as dangerous good.
Both changes described above, it would be performed via USEREXIT. However, my problem is: When the non-dangerous item is the first item of the sales order, the system does not trigger again the calculation of the schedule line dates based on the new route (XVBAP[1]-ROUTE).
I have found out the routine that changes the schedule line dates, but I do not know how to use it. Do you have any other solution?

Hi Marcelo,
You can try with User Exit MV45AFZZ (USEREXIT_SAVE_DOCUMENT_PREPARE).
Try with XVBEP. Loop at this table and copy the WADAT into EDATU.

Date Field Input Box in data table does not provide date picker???

hello everybody,
In my JSF page i have a data table in which i have a input text field of date type. my problem is for the input box date picker is not available. though i can have date picker for a date filed outside the datatable. another problem is for the date filed validation in the browser is not available too. so how can i get the helper calender and browser validation? plz help.

You are absolutely correct Sir.
I am using IBM Websphere for developing JSF and the component is
<h:inputText id="txtBirthDt" size="11">
<f:convertDateTime pattern="dd/MM/yyyy" /><hx:inputHelperDatePicker />
<hx:inputHelperAssist validation="true" errorClass="inputText_Error" errorAction="selected"/>
<hx:validateDateTimeRange maximum="#{now}" /></h:inputText>
Both the helper calender and the validation part for the date field is not working if it is included in data table. Please Help.

Issues while migrating data from a disk based table to a memory optimized table

Hi All,
I have a Disk based table with 400000000 rows in it, We are trying to convert it into a memory optimized table.
We have already created a memory optimized table with similar structure and trying to import data into this mem optimized table using 'insert into' from the disk table.
I am trying to Migrate around 10000000 rows at a time, but I am getting an error 'There is insufficient system memory in resource pool 'default' to run this query.' Altough we have 128 GB RAM on the server and SS is utilizing more than 120 GB RAM.
Altough the query has been cancelled.
Wanted to Know how could we migrate the table with the available RAM or do we have increase our RAM?

Josh,
Microsoft's documentation on this subject isn't at its best right now (I believe there will be incremental improvements for better understanding), but here is what I read so far.
http://msdn.microsoft.com/en-us/library/dn133190.aspx
"A hash index consists of a collection of buckets organized in an array. A hash function maps
index keys to corresponding buckets in the hash index."
Judging by this statement, a hash index is a hash table just like the ones used as work tables for hash operators in queries (hash matching or grouping). Doesn't contain (or include) other columns, i. e. it doesnt store any data.
"Multiple index keys may be mapped to the same hash bucket."
This means there is some kind of mapping, but this is not explained in the article above. However...
http://msdn.microsoft.com/en-us/library/dn282389.aspx
"For each hash index in the table, each row has an 8-byte address pointer to the next row in the index. Since there are 4 indexes, each row will allocate 32 bytes for index pointers (an 8 byte pointer for each index)."
Each row (in the table) has a pointer (for every index, 1:1 ratio) that points to a row (also known as bucket) in the hash index. So that is how the aforementioned mapping works huh!
> What happens if you include a column in two or three different indexes, or is that not allowed?
My conclusion is that the hash indexes works the same way as a hash worktable, with the addition of the column in the base table that is added to store pointers to the hash index.
When you create a new index, even if you use the same column twice, a hash table is created, hash calculations are distinctly made for each key and stored on it, and while this is done, the column that is exclusively used for this new index is populated
with pointers to this index. You can add a given column to the set of keys of different hash indexes as many times as you want. Correct if i'm wrong, I'm also new on this subject :D
