Solved: Re: table control wizard with delete/insert button...

former_member187651 · ‎2012 Nov 07

Hello Gurus,

I am using table control wizard in the module pool. I need two button at the top, one for delete and other for update the record. even I need to add new line to the table and save with save button.

I have made table with table control, added two button at top, one for delete and other for update. Now I stuck with very first step, that is button is not deleting the row. I have even debug the code and found one error, but don't know whats the problem. I have even check the SDN but not able to resolve the problem. I am new to Module pool. Please help. I am using se80.

I am pasting the code and showing where I am getting error while debug. Please let me know the basic steps even.

Hi,

The code is a little bit hard to follow but I believe that you don't see the row deleted because you select the data in the PBO module.

Normally every PAI module is followed by the PBO module. Even if you delete the table row in the PAI module, then the program enters the PBO module and runs Module SELECT_RECORDS Output thus refreshing your table to it's initial state (After the select).

Try entering a condition at the beginning of the SELECT_RECORDS Module like :

CHECK IT_ZEDUCATION IS INITIAL.

The code to delete a line in a TC should be like

Screen flow

PBO

module select.

...

PAI

...

module user_command

Main Program

module select.

check ITAB is initial.

* i would personally put this outside the PBO and before CALL SCREEN statement in the START-OF-SELECTION event.

select * from DBTAB into corresponding fields of table ITAB.

if sy-subrc ne 0.

* user message

endif.

endmodule

module user_command.

case sy-ucomm.

when 'DELETE'.

delete itab where mark eq 'X'.

if sy-subrc ne 0 .

* user message (or do something )

endif.

endcase.

endmodule.

As to the Search statement i don't really see it's use there. Even more SEARCH is an obsolete syntax. Unless you have a valid use for that statement I suggest you comment it.

Although TC Wizard can help you, it can also make your code difficult to read or even have statements that you don't actually need. I recommend you write the entire Screen Flow yourself so the code and the program is more manageable.

Regards,

Andrei

Dear mishra ji,

need to check below steps. might be help.

1) put a break point in PAI.

2) select any row of the table and press delete button.

3) on break point. check the internal table.

3) check the line selection field ( it should be 'X').

4) if you can not see 'X' at the selection line item in internal table.

refer your table row selection field weather it is correct or not.

if problem still persist feel free to ask.

Dear Avirat,

As you said I have put breakpoint in PAI and seen that it is taking mark 'X' at the internal table for the selected row. I have seen through debug that it is not getting value of "L_ok" . Below is the code.

Dear Mishra ji,

as you are getting 'X' mark inside table and still not able to delete line item

then

why don't you put

loop at itab where selectfield eq 'X'.

delete itab.

endloop.

manual query (in same button - function code).

you can delete record from this solution.

try it.

Hi,

The code is a little bit hard to follow but I believe that you don't see the row deleted because you select the data in the PBO module.

Normally every PAI module is followed by the PBO module. Even if you delete the table row in the PAI module, then the program enters the PBO module and runs Module SELECT_RECORDS Output thus refreshing your table to it's initial state (After the select).

Try entering a condition at the beginning of the SELECT_RECORDS Module like :

CHECK IT_ZEDUCATION IS INITIAL.

The code to delete a line in a TC should be like

Screen flow

PBO

module select.

...

PAI

...

module user_command

Main Program

module select.

check ITAB is initial.

* i would personally put this outside the PBO and before CALL SCREEN statement in the START-OF-SELECTION event.

select * from DBTAB into corresponding fields of table ITAB.

if sy-subrc ne 0.

* user message

endif.

endmodule

module user_command.

case sy-ucomm.

when 'DELETE'.

delete itab where mark eq 'X'.

if sy-subrc ne 0 .

* user message (or do something )

endif.

endcase.

endmodule.

As to the Search statement i don't really see it's use there. Even more SEARCH is an obsolete syntax. Unless you have a valid use for that statement I suggest you comment it.

Although TC Wizard can help you, it can also make your code difficult to read or even have statements that you don't actually need. I recommend you write the entire Screen Flow yourself so the code and the program is more manageable.

Regards,

Andrei

Hi Andrei,

I have gone with wizard as it gives more flexibility with table control, but of-course, code is hard to understand. For that reason I would like to go with my code. Can you please give me sample code for my scenario, so that I can proceed with that.

Thanks for your suggestion.

former_member184675 · ‎2012 Nov 08

Hi Mishra,

Check program :

demo_dynpro_tabcont_loop_at

Now,

I really don't understand the use of the code, because it does nothing but circle around a set of variables with the same value (or the same expected value) and the Form you're calling is only called from one place.

  OK_CODE = SY-UCOMM.
   PERFORM USER_OK_TC USING    'TBC_9000'
                               'IT_ZEDUCATION'
                               'MARK'
                      CHANGING OK_CODE.

FORM USER_OK_TC USING    P_TC_NAME TYPE DYNFNAM
                           P_TABLE_NAME
                           P_MARK_NAME
                  CHANGING P_OK      LIKE SY-UCOMM.

*&SPWIZARD: BEGIN OF LOCAL DATA----------------------------------------*
    DATA: L_OK              TYPE SY-UCOMM,
          L_OFFSET          TYPE I.
*&SPWIZARD: END OF LOCAL DATA------------------------------------------*

*&SPWIZARD: Table control specific operations                          *
*&SPWIZARD: evaluate TC name and operations                            *
    SEARCH P_OK FOR P_TC_NAME.                             
    IF SY-SUBRC <> 0.        
      EXIT.
    ENDIF.
    L_OFFSET = STRLEN( P_TC_NAME ) + 1.
    L_OK = P_OK+L_OFFSET.

Because:

P_OK = OK_CODE = SY-UCOMM = 'DELE'.

P_TC_NAME = 'TBC_9000'.

SEARCH P_OK for P_TC_NAME will return 4 always.

P_OK+9 = blank because DELE is only 4 chars long. You are setting an offest far away from the variable length.

I assume that what you want to achieve by the generated code is to have L_OK = 'DELE'.

But you already have that value in both sy-ucomm and p_ok

So simplify everything:

either use

CASE P_OK.

WHEN 'DELE'

delete itab where selectfield eq 'X'.

ENDCASE.

or

CASE SY-UCOMM.

WHEN 'DELE'.

delete itab where selectfield eq 'X'.

ENDCASE.

Hi Andrei,

I have made some changes to the code, as per your suggestions given.

*&SPWIZARD: Table control specific operations                          *
*&SPWIZARD: evaluate TC name and operations                            *
********   SEARCH P_OK FOR P_TC_NAME.
********   IF SY-SUBRC <> 0.
********     EXIT.
********   ENDIF.
********   L_OFFSET = STRLEN( P_TC_NAME ) + 1.
********   L_OK = P_OK+L_OFFSET.

     L_OK = P_OK.

I have commented the line where the code was no executing. and put directly L_OK = P_OK

Now code is getting executed. Records are getting deleted from internal table i.e IT_ZEDUCATION

but not deleted from ztable i.t ZEDUCATION.

Please let me know why it is doing so. What I need to do here.

Thanks

former_member184675 · ‎2012 Nov 08

well that's because you didn't tell the program to delete it from the database.

LOOP AT <TABLE> ASSIGNING <WA>.

*&SPWIZARD: access to the component 'FLAG' of the table header *

ASSIGN COMPONENT P_MARK_NAME OF STRUCTURE <WA> TO <MARK_FIELD>.

IF <MARK_FIELD> = 'X'.

DELETE ZEDUCATION FROM <WA>.

IF SY-SUBRC <> 0.

*USER MESSAGE.

ELSE.

DELETE <TABLE> INDEX SYST-TABIX.

ENDIF.

ENDIF.

ENDLOOP.

former_member187651 · ‎2012 Nov 08

Hello Andrei, Thanks for your quick reply.

I have used following code in the program but still records are nor getting deleted from zeducation.

Please let me know where I am wrong.

ASSIGN COMPONENT P_MARK_NAME OF STRUCTURE <WA> TO <MARK_FIELD>.
*       IF <MARK_FIELD> = 'X'.
*       DELETE <TABLE> INDEX SYST-TABIX.
*       IF SY-SUBRC = 0.
*         <TC>-LINES = <TC>-LINES - 1.
*       ENDIF.

      IF <MARK_FIELD> = 'X'.
             DELETE ZEDUCATION FROM <WA>.

         IF SY-SUBRC <> 0.

             MESSAGE I001(ZCH).

         ELSE.

           DELETE <TABLE> INDEX SYST-TABIX.

         ENDIF.

*       IF SY-SUBRC = 0.
*         <TC>-LINES = <TC>-LINES - 1.
*       ENDIF.
        REFRESH CONTROL 'TBC_9000' FROM SCREEN '9000'.
      ENDIF.
    ENDLOOP.

Thanks Andrei Problem solved.

Your suggestions really helped me. I will come to you if I stuck with some point with it, as I am working on it.

Former Member · ‎2012 Nov 08

Dear mishra ji,

all the codes are correct by own logic..

you are requested have a look at my previous post and need little thinking.

my given code sample is fully transparent to understand even beginner can understand...

rest is yours....

thank you.
