Posted: Tue Oct 30, 2007 11:05 am Post subject: Dynamic Table Maintenance
Author: shurasap
Compatibility: Version 6.20 and up,(4.6C - some changes required)
Summary: Finaly in version 6.20 we are able to dynamicly create internal table with the structure of database table. This allows us to dynamicly maintain any table. Please use responsibly and restrict to Z-tables only. Functionality enchanced to include dynamic selection screen option
Code:
REPORT zmtable LINE-SIZE 255
LINE-COUNT 65.
*----------------------------------------------------------------------*
* Program written by Stan Shuralyov
* Maintain Table dynamicly (Table name is entered on Selection Screen)
* Very powerfull program. Please maintain authorisation access and
* restrict maintenance to Z-tables
* Version 6.20 and up
* (can be used in 4.6C with some modifications to block try - endtry
* and classes)
*----------------------------------------------------------------------*
* Version was revised thanks to Franзois Henrotte comment
* (www.eponasolutions.com)
* Enhanced functionality with dynamic selection screen
