problem in screen painter

Former Member — Fri, 13 Feb 2009 06:40:59 GMT

hello,

i have a db table zproject_details.. it has 4 fields, proj_no(pri key), proj_name, orij_name, proj_type..

i have created 2 screens, in the 1st screen i enter the proj_no and press the 'NEXT' button to

call 2nd screen.

on the 2nd screen, there are 3 drop down list boxes in which proj_name, orij_name and proj_type

are retrieved(from zproject_details) and displayed...

if i change value of any of the field in screen 2, i have to update that record in the zproject_details

too.. so when any record is changed, i modify it in an internal table thus i can change more than

one record, and when i press 'SAVE' button, all changed records are modified in zproject_details.

this is what i have done,

module STATUS_0002 output. " ouyput of screen 2

SET PF-STATUS 'xxxxxxxx'.
SET TITLEBAR 'xxx'.

data : update1(2) value '0',

update2(2) value '0',

update3(2) value '0',

flag100(2) value '0'.

TYPES : begin of itab,

proj_no type zproject_details-proj_no,

proj_name type zproject_details-proj_name,

orig_name type zproject_details-orig_name,

proj_type type zproject_details-proj_type,

end of itab.

DATA : itab TYPE standard TABLE OF itab initial size 100

with header line,

wa type itab.

select single * from zproject_details

where proj_no = PROJ_NO.

if update1 ne 1.

move zproject_details-proj_name to ZPROJ_NAME-PROJ_NAME.

endif.

if update2 ne 2.

move zproject_details-ORIG_NAME to ZORIJ_NAME-ZORIG_NAME.

endif.

if update3 ne 3.

move zproject_details-proj_type to ZORIJ_TYPE-PROJ_TYPE.

endif.

endmodule. " STATUS_0002 OUTPUT

module USER_COMMAND_0002 input.

data : PROJ_NAME(35) type c,

if flag100 = 0.

select single * from zproject_details into itab

where proj_no = proj_no .

flag100 = 1.

endif.

case OK_CODE.

when 'PNAME'. " function code of drop down list with values proj_name

itab-proj_name = zproj_name-PROJ_NAME.

modify table itab.

if zdemo-proj_name ne itab-proj_name.

update1 = 1.

endif.

when 'ONAME'. " function code of drop down list with values orij_name

itab-orig_name = zorij_name-zorig_name.

modify table itab .

if zdemo-orig_name ne itab-proj_name.

update2 = 2.

endif.

when 'PTYPE'. " function code of drop down list with values proj_type

itab-proj_type = zorij_type-proj_type.

modify table itab .

if zdemo-proj_type ne zorij_type-proj_type.

update3 = 3.

endif.

when 'SCREEN1'.

clear : zproj_name, zorij_name, zorij_type.

leave to screen 0001.

when 'SAVE'.

modify zproject_details from table itab .

if zdproject_details-proj_name = itab-proj_name.

message i000.

else .

message i001.

endif.

endcase.

endmodule. " USER_COMMAND_0002 INPUT

when i keep debugger on change values on screen and press 'SAVE', my itab has the modified

changed values but they are not updated in zproject_details at last..

eg: if i change the proj_name on screen

after the if stmt - if zdproject_details-proj_name = itab-proj_name.

the itab has the modified value of proj_name but change has not occured in zproject_details...

i dont understand what is wrong, i even used 'update zproject_details from table itab'...

plz help me out,

thank you...

Hi aarti

Cad you try using the update command ?

Use this.

LOOP AT t_breakdown1.

UPDATE znel_breakdown FROM TABLE t_breakdown1.

ENDLOOP.

im sorry, it got copied wrong, the correct stmt is,

when 'SAVE'.

modify zproject_details from table itab .

if zproject_details-proj_name = itab-proj_name.

message i000.

else .

message i001.

endif.

Hi,

Check Sy-subrc value after Modify statement. whether it is updating the table properly.

Re: problem in screen painter

Former Member — Fri, 13 Feb 2009 07:03:43 GMT

thank you

hello Naveen,

im sorry, the stmt got copied wrong, the correct stmt is, it is not zdzproject_details and the structure

is correct, i checked it, not difficult to track, its only a 4 field table

when 'SAVE'.

modify zproject_details from table itab .

if zproject_details-proj_name = itab-proj_name.

message i000.

else .

message i001.

endif.

thank you

Did you try wid update ?

Re: problem in screen painter

Former Member — Fri, 13 Feb 2009 07:33:30 GMT

hi Matrina,

i did try with update..

i tried

loop at itab.

update zproject_details from table itab.

endloop.

then i debugged, cmpiler wont even go inside the loop, from the loop stmt, it directly jumps to end loop....

i e1 tried without loop endloop... the values dont change, in debugger after the UPDATE stmt, the itab has the modified values, but zproject_details is not updated..

thank you

hi naveen,

i checked, its only a 4 field table... actually my original project is bigger but im new to screen painter

and wanted to get concepts clear... so i did this demo screen to know how data is modified in database table from the screen, i created a database table 'zproject_details' with 4 fields proj_no(pri key), proj_name, orij_name, proj_type...

check the declaration of itab...

what is going wrong??

thank you...

hi,

itab does not go in loop probebly bcoz derz only one record in it... i have sent the code related to

screen 2, right from data declaration to the updation of the table... is the select single stmt wrong???

Re: problem in screen painter

Former Member — Fri, 13 Feb 2009 08:41:46 GMT

Aarti,

In the PAi of screen 2 you have to append values to the itab from the screen fields ...before

Module USER_COMMAND_0002 INPUT.

loop at the itab .append the screen fields to the fields of itab.append itab .endloop.

then use the modify or update to update it .

then only it ll go inside the loop of itab,.without loop if u modify it won change.

Even if one record is there it'll go insidee loop .

for e.g

this is PAI of my screen

PROCESS AFTER INPUT.

FIELD T_BREAKDOWN1-ENTRY_DATE.

FIELD T_BREAKDOWN1-PLANT.

FIELD T_BREAKDOWN1-SHIFT. (3 fields in screen)

loop at t_breakdown1.

CHAIN.

FIELD T_BREAKDOWN1-REASON.

FIELD T_BREAKDOWN1-MINS.

FIELD T_BREAKDOWN1-PICK MODULE CHECK.

ENDCHAIN.

MODULE MODIFY_TAB_9002.

(inside this i write:

t_breakdown1-entry_date = l_date.

t_breakdown1-plant = l_plant.

t_breakdown1-shift = l_shift.

t_breakdown1-reason = t_breakdown1-reason.

t_breakdown1-mins = t_breakdown1-mins.

t_breakdown1-pick = t_breakdown1-pick.

APPEND t_breakdown1.

)

endloop.

MODULE USER_COMMAND_9002.

here i give if sy-ucomm =save
