Hi,

Give field name in capital letters,

Check this

Eg.

clear fieldcat_in.

fieldcat_ln-fieldname = 'FIELD3'.

fieldcat_ln-tabname = 'ITAB1'.

fieldcat_ln-ref_fieldname = 'MENGE'. "<- REF FIELD IN THE DICTIONNARY

fieldcat_ln-ref_tabname = 'MSEG'. "<- REF TABLE IN THE DICTIONNARY

fieldcat_ln-no_out = ' '.

fieldcat_ln-do_sum = 'X'. "SUM UPON DISPLAY

append fieldcat_ln to gt_fieldcat.

hi selva,

one more query can i change the menge field from packed decimal to char it is editable in alv output . for example i got the menge as 0.0002 when i changed it to 5 it should reflect as 5 not 0.0005 after calling the method checked_changed_data . is this possible

Hi,

U can change the data type from packed decimal to char, but u can't do total and sub-total on char field.

If u don't have any requirement on total and sub total for menge field then u can change.

field catalog rules : in quotations use capital letters for fileds .

for system fileds like sy-uname ,sy-repid dont use quotations .

Mozam ,

u need to specify likewise in the filedcatalog..

fs_fcat-fieldname = 'MENGE'.
fs_fcat-qfieldname = 'MSEHI'.
modify t_fcat frm fs_fcat transporting qfieldname where fieldname = 'MENGE'.

QFIELDNAME

type- LVC_QFNAME

length- Char(30)

value range - SPACE, name of a field in the output table

Defining a reference to quantity units. The ALV links the field specified in FIELDNAME to the field for quantity units specified in QFIELDNAME . The field specified in QFIELDNAME must have a separate entry in the field catalog.

Hope this helps..
