Hi yadavdeep

Please make sure all your four columns has L_header as below. You have only two. Assign the remaining two as well.

WA_HEADER-heading = 'ID NAME'.
APPEND WA_HEADER TO L_HEADER.

WA_HEADER-heading = 'CONN ID'.
APPEND WA_HEADER TO L_HEADER.

WA_HEADER-heading = 'COUNTRY'.
APPEND WA_HEADER TO L_HEADER.

WA_HEADER-heading = 'CITY'.
APPEND WA_HEADER TO L_HEADER.

Dear Sir ,

i assigned remaining two columns in internal table.

i don't understand the meaning of DUMP

TYPE CONFLICT IN ASSIGN THE PROGRAM.

[venkateswaran_k]

The Conflict in data and header .. The data has four columns and header was having only two cols. That is the reason.

[former_member809080]

Dear sir ,

i already declared all the cols in my code .

then still give a dump.

[venkateswaran_k]

Hi yadavdeep

Do not pass .. Comment this, This is the type conflict.

Hi yadavdeep

The problem is with the table paramter you passed in gui_download (FIELDNAMES = L_HEADER).

You need not to pass this. It is optional, The type you define for L_HEADER and the type it expects in GUI_DOWNLOAD are not matching, that is why the dump,

You remove that line adn execute.

It will work

I tested here and it works.
