I m populating an excel sheet with fields from an internal table using fm GUI_DOWNLOAD. I want to add ~ symbol as seperator for each fields. If i use the WRITE_FIELD_SEPARATOR = '~' i am getting a box symbol as field seperator. I tried with other symbols like #, but then too i am getting the box symbox in output excel sheet and not the required symbol. I kindly request you to help me in this issue.
