Function module taking default value despite of giving values

[former_member1364661]

Requirement is to download a CSV file,
by default this FM takes Field separator as tabs
but here i have given field separator as ','
its still separating the Fields by Tabs.

i want to download output in CSV file.
is this FM correct way to do so.
Thank you.

WRITE_FIELD_SEPARATOR is a flag whether fields shall be separated and not the separating character, see function module documentation:

Separate Columns by Tabs in Case of ASCII Download

Description

In the downloaded file, the columns are separated by tab characters (cl_abap_char_utilities=>horizontal_tab). You should use this setting if you want to upload the data from the file at a later time, because this is the only way of identifying individual columns.

The parameter makes sense only for the FILETYPE values ASC, DAT and IBM; for DAT it is set implicitly.

Value range

'X' : Write separator.

SPACE : Do not write separator.

Default

SPACE
