Raju,
Please clarify this.
Do you have a method clear_info_refresh_visible in your component controller. I think not.
I am not able to relate your request and coding.
You can simply clear the internal table like this
clear lt_intern_tab[].
If it is a context node then you can bind a empty table to the node to make it empty.
lo_nd_data->bind_table(
     new_items            =   lt_intern_tab
     set_initial_elements = abap_true ).

How to display the Internal table records in table format?

Hi Gurus,
I want to display my print prg internal table records in d appropriate form in a table format, give some solution
with regards
Thambe

There are lot many options to do that
one way is create template in the maikn window and define the line types according to your data cretae text and put your data in the text and go to output options and give the line type to be used . You can also select details option to have lines in your output.
similarly YOU CAN CREATE TABLE IN THE MAIN WINDOW FOR THIS YOU DONT NEED TO DEFINE THE LINE TYPES .
WHEN YOU ARE IN MAIN WINDOW RIGHT CLICK ON TABLE AND GO TO PATH
CREATE -> TABLE
-> TEMPLATE
REWARD IF USEFUL

Create a Table Dynamically in WEB Dynpro Java with diferent type of column

Hi everyone, I have a question if is possible to create a table dynamically in Web Dynpro Java?, depending of the RFC consults create the rows dynamically, ,this table must have diferent type of columns, for example link column (when the user click this link execute an action and show a adobe interactive form in another view), image column (show an image depending of the information)
Thank you everyone
Atte Israel

Hello,Israel.
Yes , it is possible through dynamic programming in wdModify of the View.
You can do this ,for example, using cell variants.
IWDTable tab = (IWDTable) view.getElement("TABLE_NAME");
IWDTableStandardCell cellV= (IWDTableStandardCell) view.createElement(IWDTableStandardCell.class,"TableStandardCell"+i);
cellV.setVariantKey("NotEditableVariant");
cellV.setCellDesign((WDTableCellDesign)wdContext.nodeTableDaysTitle().currentTableDaysTitleElement().getAttributeValue("CellDesign"+i));
IWDTextView textViewi= (IWDTextView) view.createElement(IWDTextView.class,"TextView"+i); // -- here you control the type of the object that is displayed in the cell
textViewi.bindText(dayAttrib);
cellV.setEditor(textViewi);
tabColumn.addCellVariant(cellV);
tab.addGroupedColumn(tabColumn,tab.numberOfGroupedColumns());
Using this code you can control even specific cells in the table and not only columns.
Hope this helps you,

SRM 7.0 find transparent table name from Web dynpro Component

Hi ,
I am trying to find the transparent table name from Web dynpro component dictionary structure. I am working in SRM 7.0. Please let me know how to find the transpartent table for a field.
Thanks,
Monica

hi,
your question is very unclear and does not relate to performance.
SRM uses webdynpro ABAP so the recommendation will not help.
Do you need a technical UI element?
Or the application table where the business data of an UI is stored???
If it is the later, then you can use the SQL trace, change to element you are interested in, and trace it. The table should appear in the trace in connection which an UPDATE command. Still a bit cimbersome.

Help on Delete Internal table records

Hi,
I have a internal table with some records in it.
I need to delete the contents of this based on the condition as below.
if product_search-Resp_product_company is not initial.
SORT i_equi BY zzrefeng.
DELETE i_equi WHERE zzrefeng <> product_search-Resp_product_company.
endif.
when i execute this all the records are getting deleted irrespective of the condition mentioned.
Can anyone help me on this.

Hi,
Need to delete the records if <b>ZZREFENG</b> does not have the value of <b>product_search-Resp_product_company</b> .
Here I have product_search-Resp_product_company value as FI14. And also the internal table contains some records with ZZREFENG = FI14.
I need to delete the internal table records if ZZREFENG <> FI14. But when i execute the statement it is deletng all the records even ZZREFENG = FI14 records also.

How to set first_visible_row for a table on a web dynpro

How can I set the attribute first_visible_row in a table which I placed on a Web Dynpro?
I need the table to scroll automatically to a specific row depending on a date. So I'm calling a method using this date, but how can I change the attribute of the table?
Thank you!

Follow these steps,
1- Create an attribute with char1 in the view context e.g first_vis_row
2- go to the table properties in view and bind the property first_visible_row to this attribute.
3- NOw go to the wddoinit method of the view...
4- read the internal table and find out the index of the row which you want to set as first row. As in ur case you want a specific date in first row. So read the internal table and findout the index.
5- now write this code, say your attribute name is first row inside node flag1...(you can change it for yoru requirement)
DATA lo_nd_flag1 TYPE REF TO if_wd_context_node.
DATA lo_el_flag1 TYPE REF TO if_wd_context_element.
DATA ls_flag1 TYPE wd_this->element_flag1.
DATA lv_first_row LIKE ls_flag1-first_row.
* navigate from <CONTEXT> to <FLAG1> via lead selection
lo_nd_flag1 = wd_context->get_child_node( name = wd_this->wdctx_flag1 ).
* get element via lead selection
lo_el_flag1 = lo_nd_flag1->get_element( ).
* get single attribute
lo_el_flag1->get_attribute(
    EXPORTING
      name = `FIRST_ROW`
    IMPORTING
      value = lv_first_row ).
here change the lv_first_row to the index which you got after raeading the internal table.
suppose it's
lv_first_row = 4.
lo_el_flag1->set_attribute(
    EXPORTING
      name = `FIRST_ROW`
      value = lv_first_row ).
Hope it works.

Dynamic table columns in web dynpro abap

Hi,
In my current project I have got a requirement whose solution I am not able to figure out.
My requirement is this:
I will have a table containig budget owners name(since its compensation management in HR).There will be a table popin inside this table on the click of the personal number of the budget owner. Now the table popin will have another table with all employees name under that particular budget owner.
The problem is that the table inside the popin will not be having fixed columns.Actually the columns will be coming from a standard java web dynpro application (say in the form of an internal table).
My requirement is this how can this be handled?Can we include all the possible columns in the node(which i bind to the child table) and make them visible/invisible during runtime? or create a dynamic node and assign it to the table(but in this case a node needs to be bound to the table during design time,what to bind?) ?
Can u please help along with code snippets.
Thanks and Regards,
Saikat.

Thnx for the input.
I am abke to make the table columns inside the popin visible/invisible.
I have a tabstrip.Indise one of the tabs is my main table and inside one of the columns is the popin.Inside that a transparent container and finally the table inside that.
This is the code that worked for me.
METHOD wddomodifyview .
DATA lr_root_container TYPE REF TO cl_wd_uielement_container.
DATA lr_table_popin TYPE REF TO cl_wd_table_popin.
DATA lr_transparent_container TYPE REF TO cl_wd_transparent_container.

IF first_time = abap_false.
    lr_root_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
    lr_tabstrip ?= lr_root_container->get_child( id = 'TABSTRIP1' ).        "GETTING THE TABSTRIP
    lr_tab      ?= lr_tabstrip->get_tab( id = 'TAB1' ).        "GETTING THE TAB INSIDE TABSTRIP
    lr_table    ?= lr_tab->GET_CONTENT( ).      "GETTING THE CONTENT(TABLE IN THIS CASE) INSIDE TABSTRIP
    lr_table_column ?= lr_table->get_grouped_column( id = 'TABLE_MAIN_PERNR' ).   "GETTING THE COLUMN INSIDE THE TABLE
    "Table popin
    lr_table_popin ?= lr_table_column->GET_POPIN( ).   "GETTING THE POPIN INSIDE THE TABLE
    lr_tc ?= lr_table_popin->GET_CONTENT( ).   "GETTING THE CONTENT(TRANSPARENT CONTAINER IN THIS CASE)INSIDE THE TABLE
    lr_table2 ?= lr_tc->get_child( id = 'TABLE_EMPLOYEE' ).        "GETTING THE EMPLOYEE TABLE INSIDE THE TRANSPARENT CONTAINER
    lr_table2_column ?= lr_table2->get_grouped_column( id = 'TABLE_EMPLOYEE_PERNR' ).   "GETTING THE COLUMN INSIDE THE TABLE
    lr_table2_column->SET_VISIBLE( '02' ). "SETTING VISIBILITY FOR THE COLUMN
ENDIF.
ENDMETHOD.
But I'm still considering the dynamic node concept.Lets see if this works out or not.If not then I'll have to go for the dynamic node thing.

Reg : Joining the all internal table records into a single internal table

Hi all
I am having 5 internal tables and i want to put all these entries in a single intrnal table and my requirement is for each and every record it has to go through all the internal tables and if an entry is missing meand.it has to go through the other internal tables and for missing entries i should leave it as blank and rest of the contents i have to display can any please gimme some logic how to do this??
Thanks in advance

Don't have time or will to deliver turnkey solutions, but here is a frame:
LOOP AT itab1...
READ TABLE itab2 WITH TABLE KEY... (fields linking itab1 and itab2)
READ TABLE itab3 WITH TABLE KEY... (fields linking itab1 and itab3)
LOOP AT itab4 WHERE... (fields linking itab1 and itab4)
    READ TABLE itab5 WITH TABLE KEY... (fields linking itab4 and itab5)
    MOVE-CORRESPONDING... (all five work areas to target work area)
    APPEND itabtarget...
ENDLOOP.
ENDLOOP.
so use READ when there is a 1:1 relationship (e.g. check table entry), and LOOP when there is a 1:N relationship (e.g. items for a header)

How to send Internal table records to Idoc Inbound posting FM to create Ido

Hello Experts,
I have all the data necessary to create shipments in one internal table inside my ABAP program.
I can use BAPI_SHIPMENT_CREATE to create shipments. But associated with this BAPi there is one ALE message type SHIPMENT_CREATEFROMDATA. Now my requirement is to use this message type to cretae my shipments via idocs for one scenario for some of the records in the internal table.
For this message type, I got the inbound function module IDOC_INPUT_SHIPMENT_CREATEFROM from TBDBE table.
Can anybody please let me know how to send the data from the internal table to this inbound function module?
Becasue it has mandatory parameters INPUT_METHOD, MASS_PROCESSING. What values should be passed to these parameters if the data has to be sent to this function module?
Regards.

Hi Ravikanth,
Thankyou very much for your quick reply.
So If I split my internal table data and populate IDOC_DATA and IDOC_CONTROL and pass to the inbound function module directly in my ABAP program, will that be going to create idocs and post shipments?
I mean is it enough to call the Inbound posting function module directly in my ABAP program or any other FMs to be called to take care of ALE settings and shipment creation?
Please confirm.

How to Refresh "Internal table values" in User EXIT.

Dear All,
My requirement is to place some checks in exit ZXQQMU20 in different tabs from the TCODE IW21 . IW22 etc.
Now after placeing the checks towards the different tabs while doing "NOCO" from IW21 the conditions are fullfilled but
when i go ahead to modify the created "NOCO " from the TCODE IW22 by deleting the created values and saving in IW22 , the conditions written in the exit are still satisfied eventhough i have deleted the values in IW22.
The reason for this is that the tables which are there in the exit ZXQQMU20 T_VIQMFE , T_VIQMUR , T_VIQMMA
still contains the old values which were there at the time of creation of "NOCO" in IW21 .

Hi, I was thinking just like XVBAP and YVBAP values in the USEREXIT_SAVE_DOCUMENT.
Plz check u have x /y versions or tables like _old/ _new suffixes and then move the value accordingly.
otherwise there may be inconsistency.

What is the right way to display a table in Java web dynpro using a node.

Hi experts,
I am trying to show a node of cardinality 0...n as a table in an adobe form in Java web dynpro. But its not showing it properly. Can anybody please tell me what is the right way to display a table on adobe form using a node of cardinality 0...n or 1...n in Java Webdynpro. In ABAP webdynpro, we can drag and drop a node of cardianlity 0...n or 1...n to show as a table and it works fine. Is the same possible in Java webdynpro also. Please help.
Thanks and Regards.

Please refer to my post.. you will get the answer
Dynamic Table - same data repeating in all rows
Special care should be taken in designing the context for table attribute.
The attribute type singletone also plays a important role. I have this doubt from the beginning when you have reported this problem for the first time but finally you marked it as solved so i thought there might be some other issues but again when you reported that again i did some analysis.
Now coming to final solution :
For designing a table in adobe interactive form you have consider following
You have to design the view context upto three level, I am explaining you the properties
PDFDataSource (Parent Level1) - Cardinality 1:1 - Signetone -True - This is assigned to datasource
TableList (Parent Level2) - Cardinality (1:1) - Signetone -True
TableWrapper(Parent Level3) - Cardinality (0:n) - Signetone -True
TableData (Parent Level4) - Cardinality (0:1) - Signetone - false (This is the main point)
Then under TableData value node, you have to put all your table attributes.
This Value Node name can be anything but hierarchy should be same as I have mentioned above.
Please try out these steps and get back to me if you have any doubt.

Doubt in internal table record count

Hi,
i have an internal table with 5 fields. Last field is flag. In my internal table lot many records are there. i want to count only the records with flag 'E'. How to count the total records with 'E'.
Mohana

Try like this,
Data: c type i.
Loop at itab into wa.
if wa-flag = 'E'.
c = c + 1.
endif.
Endloop.
Write:/ 'Total records', c.
OR
LOOP AT itab WHERE flag = 'E'.
c = c + 1.

Points will be rewarded.
Thanks,
Suresh.U

you could:
sort T_PA2002 by pernr.
sort T_PA9003HRABS by pernr.
loop at T_PA2002
read table T_PA9003HRABS with key
pernr = T_PA2002-pernr
begda = T_PA2002-begda
binary search.
***here you can specify how you calculate
***your absences and apply them to your
***final internal table.
endloop.
hope this helps.
