Addition of Custom fields to QM01 Tcode:
Go to function group XQQM
,create the screen under screens tab number 0090.
Declare the screen fields under include tab ZXQQMTOP .
data :
dist  like qpcd-code,
sal   like qpcd-code,
cust  like qpcd-code.
Under process on value-request. Create a module for f4 help
for the custom fields.
Under the function module EXIT_SAPMIWO0_008 write the code for updation of custom fields to
the structure  viqmel.
Under PAI create a module for capturing the screen field
values.
Case sy-ucomm.
when '10\TAB02'.
viqmel-cust = cust.
viqmel-dist = dist.
viqmel-sal = sal.
endcase.
For
QM02 and QM03use EXIT_SAPMIWO0_008 for display of
the screen field values.
Under the PBO of the screen create a module for fields to
be in display mode.
if sy-tcode = 'QM03'.
loop at screen.
if sy-ucomm = '10\TAB02'.
screen-input = 0.
modify screen.
endif.
endloop.
endif.
