In my case, I am trying to export a CSV file to the server with open dataset in a function module.
An internal table (itab) with different structure will be passed in to my FM.
I need to loop at the itab to read each line,
and then read each field value and concatenate into output_line.
This made the result to be a flat structure transfer to the open dataset for a new file.
I know that field-symbol can be used in the first loop of assigning lines of table to the field symbol <fs>. However, how can I get the value of each field?
Since the itab structure will be changed when passing different itab into the FM.
I cannot use <fs>-field_name to retrieve the data.
It is not a matter about what the data type is. Just need to concanate all the field values.
loop at itab into <fs>. " Loop at the itab Loop at <fs>. " Loop at the table-line * Read field value into <fs>-field " Get the value of the field concatenate out_line '","' <fs>-field into out_line " Add Field value to output line endloop. concatenate '"' out_line '"' into out_line. " Formate the output line transfer out_line to csv_file. " Write the output line to output file endloop.
