Version 2.0
Author WATTO
Source from: http: /www.watto.org/program/abap/download/Z_TABLE_DATA_DOWNLOAD.abap
Description: Generates a dynamic program that allows you to download data from a table, with specified download and selection fields.
Code:
***********************************************************************************************************
* Program: Z_TABLE_DATA_DOWNLOAD
* Restrictions: -Should be run in the background, for large tables
* -If run in production, should be run after business hours, as it could cause system
* performance issues
* Description: Given the name of a database table, a program is generated that allows the user to enter
* values for each field in the table. When the generated report is run, the contents of the
* table are downloaded to a unix file.
*
* The user is prompt to choose the fields to appear on the selection screen of the program
* (up to 40 fields) and the fields to write to the downloaded file.
*
* The generated program can be run in the background, via the Program menu on the selection
* screen of the generated program.
