Designed Maint
The Custom Maintenance, have the same operating than the automatic maintenance. However it is possible to completely change the display, remove fields or add fields from other related tables. For example if an items sheet have a supplier code, we can add as screen data itself name (although only viewable not modifiable), or the current balance of this provider.
The way to do this is explained in the documentation AppDesigner or http://downloads.dsoft.es/ftp/Help/Windows/developer/.
