Answer 1

It is dependent on these profile parameters. Your system administrator will set these during installation and may be changed as needed.
"o  ztta/roll_area            (1.000.000 - 15.000.000)               
       Classic roll area per user and internal mode                 
       usual amount of roll area per user and internal mode         
o  ztta/roll_extension       (10.000.000 - 500.000.000)             
       Amount of memory per user in extended memory (EM)            
o  abap/heap_area_total      (100.000.000 - 1.500.000.000)          
       Amount of memory (malloc) for all users of an application    
       server. If several background processes are running on       
       one server, temporary bottlenecks may occur.                 
       Of course, the amount of memory (in bytes) must also be      
       available on the machine (main memory or file system swap).  
       Caution:                                                     
       The operating system must be set up so that there is also    
       enough memory for each process. Usually, the maximum address 
       space is too small.                                          
       Ask your hardware manufacturer or your competence center     
       about this.                                                  
       In this case, consult your hardware vendor                   
abap/heap_area_dia:        (10.000.000 - 1.000.000.000)             
       Restriction of memory allocated to the heap with malloc      
       for each dialog process.                                     
Parameters for background processes:                                
abap/heap_area_nondia:        (10.000.000 - 1.000.000.000)          
       Restriction of memory allocated to the heap with malloc      
       for each background process.                                 
Other memory-relevant parameters are:                               
em/initial_size_MB:         (35-1200)                               
       Extended memory area from which all users of an              
       application server can satisfy their memory requirement.
