Module and Perform usage

[Former Member]

Dear Experts,

What is the difference b/w the usage of Module & Endmodule-- and Perform &Form.

Does it make any performance difference in using one or the other interchangeably

Plase advide.

You would not be able to call MODULE other than Dynpros (Screens) Flow logic.

The data declared in the MODULE would be considered as the GLOBAL data, so, better to use the Subroutines (FORM.. ENDFORM) because in the Subroutine, you can declare local data.

Hi Amit,

Modules are used in Dialog's or Module Pool Programs,,,,! It is used to navigate through the Screens for PAI & PBO events.

Where as Performs are the Blocks of Code used to reuse within the same program.. It consists of Formal & Actual parameters which you can declare as Global or Local...! Aslos dependng upon the requirement we can pass the data to Performs in thre ways,, call/pass by value , call/pass by value & return, call/pass by reference...!

Thanks & regards,

@ Fun

The only performance difference it makes is the time you wasted in thinking the performance difference between Module and perform.
