Use of memory id

Question

friends let me know the use of memory id on a report statement?

Answer 1

It stores the parameter to a memory location while transporting a parameter from one program to another. Following are the examples of two program which use memory id to transfer the internal table from one to another.
report  z_82235_test1                           .
types: begin of tab1,
         a(1),
         b(1),
       end of tab1.
types: begin of tab2,
         c(1),
         d(1),
       end of tab2.
data: itab1 type table of tab1,
      wa1 like line of itab1,
      itab2 type table of tab2,
      wa2 like line of itab2.
wa1-a = '1'.
wa1-b = '2'.
append wa1 to itab1.
clear wa1.
wa1-a = '3'.
wa1-b = '4'.
append wa1 to itab1.
clear wa1.
export itab1 to memory id '001'.
export itab2 to memory id '002'.
submit z_82235_test2 and return exporting list to memory .
import itab1 from memory id '003'.
import itab2 from memory id '004'.
write:/ 'ITAB1'.
loop at itab1 into wa1.
write : / wa1-a, wa1-b.
clear: wa1.
endloop.
write:/ 'ITAB2'.
loop at itab2 into wa2.
write : / wa2-c, wa2-d.
clear: wa2.
endloop.
report  z_82235_test2                           .
types: begin of tab1,
         a(1),
         b(1),
       end of tab1.
types: begin of tab2,
         c(1),
         d(1),
       end of tab2.
data: itab1 type table of tab1,
      wa1 like line of itab1,
      itab2 type table of tab2,
      wa2 like line of itab2.
import itab1 from memory id '001'.
import itab2 from memory id '002'.
itab2[] = itab1[].
wa1-a = 'a'.
wa1-b = 'b'.
append wa1 to itab1.
clear wa1.
export itab1 to memory id '003'.
export itab2 to memory id '004'.
