    See the below code :

    parameters: d1 type localfile default


    data: begin of itab occurs 0,

    field1(20) type c,

    field2(20) type c,

    field3(20) type c,

    end of itab.

    data: str type string.

    constants: con_tab type x value '09'.

    • if you have a newer version, then you can use this



    • con_tab type c value



    itab-field1 = 'ABC'.

    itab-field2 = 'DEF'.

    itab-field3 = 'GHI'.

    append itab.

    itab-field1 = '123'.

    itab-field2 = '456'.

    itab-field3 = '789'.

    append itab.

    open dataset d1 for output in text mode.

    loop at itab.

    translate itab using ' # '.

    concatenate itab-field1 itab-field2 itab-field2

    into str

    separated by con_tab.

    translate str using ' # '.

    transfer str to d1.


    close dataset d1.

    above code for tab delimited.

    for heading then you can write simple logic in the loop of internal table

    loop at itab.

    if sy-tabix = 1'

    move heading data to file.
