Maintenance Z-tables

Normally you can use transaction SM30 to maintain Z-tables. But because of authorization problem i had to create a transaction per Z-table. On SDN my problem was solved by using an abap with the following source code : call function 'VIEW_MAINTENANCE_CALL'      exporting           action                 = 'u'           view_name              = 'Ztable'           check_ddic_mainflag    = 'X'      exceptions           foreign_lock           = 2           no_tvdir_entry         = 8.
