Passing data between programs using OOA

[Former Member]

Hello Experts,

I have program1 with selection screen and using class methods to fetch data. Now i have the data stored in both

1) Instance variable and

2) Static variable

Now i need to pass this data to program 2 and i am using Submit and return.

In Program 2 when i try to read the Static method to get the data, there is no data returned. its all empty. any thoughts?

*** Code snippet as below *** PRG 1 **********

  o_sel->v_arbgb = p_arbgb.
  o_sel->t_msgnr_range = s_msgno[].

CALL METHOD o_data->get_data "Uses the selection screen values and fetches the DB values.
  EXPORTING
    o_sel  = o_sel.

**CALL METHOD yggtest1_data1=>get_stored_data
**  IMPORTING
**   it_data = lt_t100.  "Returns data of 10 records

SUBMIT yggtest2 and RETURN.

*** Code snippet as below *** PRG 2 **********

CALL METHOD yggtest1_data1=>get_stored_data
  IMPORTING     it_data = lt_t100

lt_t100 returns no data -even though there is 10 records before the submit statement.

any thoughts do please share?  All i would like is to use OOA to pass data between different reports, instead of Export/Import memory

Hi

uh... as i know, there is no concept is you could transport objects by OO in ABAP.

Anyway you need export to memory, export a OO instance to memory or a itab.

Need gurus to confirm this,

And this is class named as 'cl_salv_bs_runtime_info' could get last data from last program you submitted.

Hi,

The static methods/attributes call is invalid across different contexts( valid only in the same program where its used ).

For you scenario, you can have a look into http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/307d791b-3343-2e10-f78a-e1d50c7cf...

Hi,

Please try to use IMPORT and EXPORT parameters. This makes your program easy and problem will be solved.

Hi AB GK,

Try to use a singleton class which has an access to a public attributes. You can access the same instance during runtime and sharing the data between two program. It's the other way of using import and export.

A singleton class can achieve this?

Say,

A singleton class with global public attribute in program A.

And in program B, submit A, then B can access the attribute of singleton class???

SUBMIT replaces internal session, or with AND RETURN creates new one. So previous singleton instance will not be visible in SUBMITed program.
