Passing data between two programs using FMs?

[niti_mod]

Hello everyone,

Is there a way to pass data between two programs using function modules.

i know there are other options such as submit a program,export/import to memory id etc

But is it possible to pass data using FMs?

Regards,

Suppose i need to pass data to another program using FM how should i proceed.

eg

program1 the user gives an input as 1 which is type integer

now this value '1' should be available to some other program for further processing.

but i need to use only function module.

is it possible and how??.

Hi Niti,

this is possible as long all programs run in the same process, are not interrupted by any screen i/o.

create two FMs in one function group. In TOP include, declare the data to be shared globally :

* INCLUDE ZXYTOP.
DATA:
  datacontainer type whatever.

FUNCTION Z_XY_EXPORT.
* IMPORTING
*   I_datacontainer TYPE whatever
  datacontainer = I_datacontainer.
ENDFUNCTION

FUNCTION Z_XY_IMPORT.
* EXPORTING
*   E_datacontainer TYPE whatever
  E_datacontainer =datacontainer.
ENDFUNCTION

REPORT Z_PROG1.
...
CALL FUNCTION Z_XY_EXPORT
  EXPORTING
     I_datacontainer = your_datacontainer_just_filled.
...

REPORT Z_PROG2.

CALL FUNCTION Z_XY_IMPORT
  IMPORTING
     E_datacontainer = your_datacontainer_needed_here.
...
...

If you want to share the data between independent work processes and/or users, you can make use of shared buffers or the modern way shared objects.
