Separate programs

Sometimes, some programs are needed to be prevented to run with other related programs such as local UPDATE programs without lock or ones using temporary interface tables.

So programmers need to separate those programs but HOW? Here is one solution for checking running programs each other.


  data : th_opcode(1) type x,
        with_cpu    type x value 0.


constants: opcode_wp_list like  th_opcode value 1.

 data: begin of wp_tabl occurs 10.
         include structure wpinfo.
 data: end of wp_tabl.

 free : wp_tabl.

 call 'ThWpInfo' id 'OPCODE' field  
                     opcode_wp_list
                 id 'TAB' field 
                     wp_tabl-*sys*
                 id 'CPU' field 
                     with_cpu.

loop at wp_tabl.
  if   wp_tabl-wp_report = 'SAPMZTAD'. 
    or wp_tabl-wp_report = 'ZMXZT52' .
     message e100(zi)
        with 'Other related programs   
              are running now.'.  
   endif .
 endloop.
