Looking for some clarification on Datasets

[Former Member]

Alright, I need to read in a csv file that contains several lines. The delimiter is ^. This file holds one line that has the header information for a sales order. The subsequent lines are individual line items (1-many). How can I read one line at a time and end when I reach the end of the file? I would be reading the line into a string and split it from there.

Regards,

Davis

I should add that this is a background job, or will be a background job. That means that I will be using datasets and can't use anything related to the GUI.

Hi,

In that case, you can read the lines of file in Text mode. Get the line into a string and then use SPLIT command to split the values at '^' into the table fields.

Do I just do something like this?

do.
   read dataset filepath into filestring.
   if sy-subrc <>0.
      exit.
   endif.

*split string*

enddo.

Yes, but you have to use the OPEN DATASET command before trying to read it.

If you search the forum, you'll see many examples of exactly how to do this.

Hi,

Use function module GUI_UPLOAD, pass 'X' to parameter HAS_FIELD_SEPARATOR.

Check the documentation for more details.

Hi,

You can use these FM RKD_WORD_WRAP or SWA_STRING_SPLIT.
