Very often as developers, we are required to write programs that read data based on some business logic, then download. Usually this kind of requirement is handled using functions DOWNLOAD, WS_DOWNLOAD or GUI_DOWNLOAD. This feature has few drawbacks -- fixed length files, only tab/no delimited files, formats of date, quantity and currency fields.
All the above limitations can be very easily overcome by using the function SAP_CONVERT_TO_TEX_FORMAT. This function module will take any internal table as input and convert the data accordingly, using various formatting options defined at data element level, and it will give you the output in text format. In addition, this function will make use of any delimiter you want.
The program below demonstrates the above functionality. Here, we are reading data from table EKKO and downloading the data as '|' delimited file.
Editor's note: This tip works on SAP versions 4.6 or higher.
