How to fill listbox for some lines in a table control

I have a table control associated to a database table. I would like to enable several lines in the table control for the user to input data. I have a field defined as a listbox with key. In PBO -> I fill the listbox based on the value of field u201CAu201D. I execute a select using value of field u201CAu201D.
If I maintain module tc_zmovi_wm_change_tc_attr OUTPUT as the wizard created it:
MODULE tc_zmovi_wm_change_tc_attr OUTPUT.
    DESCRIBE TABLE i_zmov_wm LINES tc_zmovi_wm-lines.
ENDMODULE.
I have no problem with the listbox ( it is filled normaly) but user has a unique line enabled in the table control to input data.
If I change the module in this way:
MODULE tc_zmovi_wm_change_tc_attr OUTPUT.
DATA: v_lineas type i.
tc_zmovi_wm-lines = v_lineas + 10.
ENDMODULE.
There are 10 lines enabled to input data for the user but the list is not filled whenever user filles field u201CAu201D.
How could I solve this problem?
Thanks.

How to get the Number of lines displayed in table control in bdc

Hi,
when we write a bdc for a standard transaction, if we encounter a table control, we fill the values for each record like field(01), and the second record field(02) .......and so on..
if only 3 records are displayed in the screen and if we have 5 records to be filled in the table control, how to write the logic for that?
how to track of how many lines are getting displayed in the table control .. again it depends on the screen resolution i think..
useful answers will be rewarded
shekhar

Hi,
Here is the solution code for this :-
data for controlling paging on screen 0102
DATA: W_MAXLINES(2) TYPE N,
W_NEXT_LINE(3) TYPE N,
W_PAGE(1), "y = page forward, n otherwise
W_SCRLEN(2) TYPE I,
W_SCRLINE(2) TYPE I.
DATA: BEGIN OF W_HDR.
INCLUDE STRUCTURE D020S.
DATA: END OF W_HDR.
DATA: BEGIN OF W_FLD OCCURS 100.
INCLUDE STRUCTURE D021S.
DATA: END OF W_FLD.
DATA: BEGIN OF W_LOG OCCURS 20.
INCLUDE STRUCTURE D022S.
DATA: END OF W_LOG.
DATA: BEGIN OF W_MC OCCURS 20.
INCLUDE STRUCTURE D023S.
DATA: END OF W_MC.
DATA: BEGIN OF W_DYNPRONAME,
PROGRAM(8) VALUE 'SAPMM60X',
DYNPRO(4) VALUE '0102',
END OF W_DYNPRONAME.
FORM GET_MAX_LINES.
set w_maxlines to the number of var-loop occurrences on the screen so
that we know when to page forward on screen 0102
also initialise w_next_line to zero for GET_NEXT_LINE
this subroutine caters for all cases - including screens without loops
CLEAR: W_MAXLINES,
W_NEXT_LINE.
IMPORT DYNPRO W_HDR
W_FLD
W_LOG
W_MC
ID W_DYNPRONAME.
LOOP AT W_FLD WHERE LTYP EQ 'L'.
MOVE W_FLD-LINE TO W_SCRLINE. "first var-loop line
MOVE W_FLD-LBLK TO W_SCRLEN. "depth of loop block
EXIT.
ENDLOOP.
IF SY-SUBRC EQ 0
AND W_SCRLEN NE 0.
sy-srows = total no of lines on screen
w_scrline = actual first line of loop so that
w_scrline - 1 = number of heading lines (before loop)
4 = no of lines at top of screen - command line, pushbuttons, 2 ulines
3 = no of lines after loop - uline & Page count
w_scrlen = no of lines in loop block
w_maxlines = sy-srows - ( wscrline - 1 ) - 4 - 3
and then 1 less but not sure why!
W_MAXLINES = SY-SROWS - W_SCRLINE - 1 - 4 - 3.
W_MAXLINES = W_MAXLINES - 1.
W_MAXLINES = W_MAXLINES DIV W_SCRLEN.
ELSE.
MOVE 99 TO W_MAXLINES. "this required if no screen loop
ENDIF.
ENDFORM.
FORM GET_NEXT_LINE.
set w_page if page forward is required
W_NEXT_LINE = W_NEXT_LINE + 1.
IF W_NEXT_LINE GT W_MAXLINES.
W_NEXT_LINE = 1.
W_PAGE = 'Y'.
ELSE.
W_PAGE = 'N'.
ENDIF.
ENDFORM.
Hope it helps.

How to find out the selected line in the table control

Hi Guys,
i have a requirement like this. i have table control and the internal table for that table control as IT_CASE. this internal table i declared as CHECKBX, MATNR, QUANTITY. but when i am enter the values in the table control i am getting the values in MATNR and QUANTITY in the that internal table IT_CASE. but when iam selecting that that line iam not getting CHECKBOX as 'X' in that internal table IT_CASE. i declared the table control as CAS_CONTROL and in that i have given the "w/selcolum" property as IT_CASE-CHECKBOX. now i want to fill that CHECKBOX as 'X' inthat internal table IT_CASE whatever the lines we are selecting only for those lines i want to fill up as 'X' in that internal table.
Can you please suggest any one reg this.
Thanks in advance

Hello body,
You can give a name such as 'SEL' in w/selcol and declare SEL as char1. Then follow the coading.
in TOP.
data: sel type c.
PROCESS AFTER INPUT.
user_command_0011.
loop at <Your internal table>.
module get_data.
endloop.
Inside Module get_data.
    if sy-ucomm = <Your Fcode>
    if sel = 'X'.
       <Your internal table>-<Field for checkbox> = 'X'.
      append <Your internal table>.
    endif.
endif.
I think your issue is resolved.

Hi
You can only indicate the user and all profiles of the user will be deleted.
DATA: BEGIN OF T_DEL_USR OCCURS 0,
                 USERNAME LIKE BAPIBNAME-BAPIBNAME,
      END   OF T_DEL_USR.
DATA T_RESULT TYPE STANDARD TABLE OF BAPIRET2
WITH HEADER LINE.
After loading the users to be deleted:
LOOP AT T_DEL_USR.
CALL FUNCTION 'SUSR_BAPI_USER_PROFILES_DELETE'
    EXPORTING
       USERNAME = T_DEL_USR-USERNAME
    TABLES
        RETURN = T_RESULT.
ENDLOOP.
I'm not sure but perhaps u have to use bapi for commit too: BAPI_TRANSACTION_COMMIT

How to fill data for asset accoutning datasources

hi gurus
i want to know how to fill data for the FI:asset accounting data sources.As these datasources are not related to Logistics,i think filling setuptables concept doesnot come into picture here.thenhoe to fill data for the datasources:0FI_AA_001,0FI_AA_005,0FI_AA_006
Pls give me some inputs ASAP
Its very Urgent
Thanks in Advance
Surya Reddy

Hi,
Asset Accounting works with Timestamp mechanism. No Setup table concept like logistics. Find the prerequisites for AA extraction.
For Asset Accounting Delta Extraction you first need to have this BADI - FIAA_BW_DELTA_UPDATE active in the system:
Check the link below for more details about the badi and the delta extraction procedure.
http://help.sap.com/saphelp_nw04/helpdata/en/a8/f4153c4eb5d82ce10000000a114084/frameset.htm
Sequence of Data Requests
For summarization of line items by master record characteristics (such as cost center) during posting of ODS objects to Info Cubes, master data must already exist prior to extraction of transaction data.
Also the following sequence must therefore be kept to during extraction:
1. 0FI_GL_4 General Ledger: line items (if required)
2. 0ASSET_ATTR_TEXT Asset sub number (flexible updating)
3. 0ASSET_AFAB Depreciation area real or derived
Then the transaction data
0FI_AA_11 FIAA: transactions and / or
0FI_AA_12 Posted depreciations (period values)
Hope it helps

How do I execute some code when a line of a table control is selected?

Hi,
I would like to execute some code when a line of a table control is selected. At the moment I have to select one or multiple rows and then press enter, this forces a screen refresh and my code is executed but I would like the code to be executed as soon as any line is selected.
I've done something like this using ALV grids and object orientated code but is there a way of doing this in a normal non-OO table control?
Thanks in advance.

How can we do the validation for non visible records in table control.

Hi Experts,
I have a table control which displays list of material details. I have a button to upload the material details from excel file to table control directly. I have to validate all the customers which are exist in the table. But my item (Material) table control displays only 5 rows i.e only 5 entries are visible in module pool screen. The validation is done for 5 records only in PAI event, but i need to do validation for rest of the records too (Which are not visible on items table), if validation fails then needs to display error message.
How can we do the validation for non visible records in table control.

How to transfer the contents of a line of a table control to second screen?

Hi,
I have a table control and I have entered some contents in one line of a table control .
When i click on this line and then click on the detail button on the screen , it should take me to another screen and whatever I have entered in the table control should be transferred to the second screen .
Please could anyone help me out with this .
Regards,
Sushanth H.S.

Hi
U need to get the index of the line of table control by command GET CURSOR:
PROCESS PAI.
LOOP AT ITAB.
   MODULE GET_CURSOR.
   MODULE MODIFY_ITAB.
ENDLOOP.
MODULE USER_COMMAND.
Module to pick up the selected line:
MODULE GET_CURSOR.
GET CURSOR LINE VN_LINE.
ENDMODULE.
Module to transfer the data from table control to internal table:
MODULE MODIFY_ITAB.
ITAB-FIELD1 = <FIELD OF TABLE CONTROL>.
MODIFY ITAB INDEX <TABLE CONTROL>-CURRENT_LINE.
ENDMODULE.
U should considere the variable line has the value of the index of the line of table control, so u need to calculate the number of the corresponding line of internal table:
MODULE USER_COMMAND.
CASE OK_CODE.
    WHEN 'DETAIL'.
* Calculate the line of internal table:
       VN_LINE = <TABLE CONTROL>-TOP_LINE + VN_LINE - 1.
* Read the data
       READ TABLE ITAB INDEX VN_LINE.
* Transfer the data to the output structure of the new screen
       <STRUCTURE>-FIELD1 = ITAB-FIELD1.
* Call the new screen
       SET SCREEN <NEW SCREEN>.
       LEAVE SCREEN.

How to show asterisk for required fields in a table row?

Hi Folks,
For showing the asterisk (*) for required fields in a form, I used to give required="true" for the component and surround the component with a af:panelLabelAndMessage for which I set showRequired="true". How to do this for a component in a table row. For a component in a table, there is no label per se. The required=true flag in the component shows proper error message saying that it is required but there is no (*) for that component.
Thanks
Vishal

Table does not have any required attribute.But column has showRequired property .You can used this.If column has input text then also you put required true on this component.And set your required messages there .
It will resolve your problem
Thanks

How can we delete a line from the table control .

hi all
how can we delete a line from the table control .
situation is.
created table control in se51 which will display the data of a table.
how could i select a line from the table control ?
how could i delete the selected lines form the table.
thanks in advance

Change the Table Control attributes such that user can only select a single record(row).
<u>Tip to delete a selected record</u>
1) write a module 'Mark' in the PAI as below
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
LOOP WITH CONTROL table_view.
MODULE read_table_control.
FIELD flag MODULE mark ON INPUT.
ENDLOOP.
MODULE user_command_0100.
2) Module Mark is below.
MODULE mark INPUT.
CHECK flag = 'X'.
x = table_view-top_line + sy-stepl - 1.
Delete itab INDEX x.
ENDMODULE. " mark INPUT
Table_view is the TableControl Name.
'flag' is of type char(1) available in the Internal table which was assigned to the select option in the table control.
<u>award if uesful</u>
