Regarding "Function Modules"

Former Member — Thu, 23 Nov 2006 07:50:27 GMT

Hello Friends, I am Goli Pradeep, new to this Community...

I have a doubt in Function Modules...

Program--

types: begin of tw_vbak,

vbeln type vbeln_va,

vkorg Type vkorg,

vtweg type vtweg,

end of tw_vbak,

tt_vbak type standard table of tw_vbak.

data: lw_vbak type tw_vbak,

lt_vbak type tt_vbak,

lf_vbeln type vbeln_va.

selection-screen begin of block b1 with frame title text-001.

<b>*select-options: so_vbeln for lf_vbeln.</b>

selection-screen end of block b1.

start-of-selection.

call function 'z_somefunction'

exporting

lm_vbeln = so_vbeln.

tables

ta_vbak = lt_vbak.

......................................................

...................................................... "REST OF THE PROGRAM CONTINUES

In the above program marked with '*', there generally we declare as

<b>parameters: so_vbeln type vbeln_va.</b>

but I want to pass the range of values to function which is possible through "select-options" only

I came to know that Global data in Function Modules is used for such programs...

Here my intension is to pass the select option value to the function module which contains a range of value, so now in that function module i have to fetch records from database table VBAP in that range...

so friends please guide me to solve this problem...

hi,

u can create a range for that.

Define a range:

Ranges: r_field for <table>.

if not field1 is initial.
r_field-sign = 'I'.
r_field-option = 'EQ'.
r_field-option-low = field1.
append r_field.
endif.

if not field2 is initial.
r_field-sign = 'I'.
r_field-option = 'EQ'.
r_field-option-low = field2.
append r_field.
endif.

if field1 is initial and field2 is initial.
r_field-sign = 'I'.
r_field-option = 'EQ'.
append r_field.
endif.

select * from <table> where field1 in r_field.

rgds

hi Pradeep,

WELCOME TO SDN ...

Use Ranges ..

RANGES:r_balance FOR oiuh_rv_gl-gl_trans_am,
       r_prevbal    FOR oiuh_rv_cyc-yc_acct_perd_dt,
       r_currbal    FOR oiuh_rv_cyc-yc_acct_perd_dt.

Hi,

you can declare "lm_vbeln" import parameter in the function module, of the type 'RSPARAMS' and pass the select option to it.

Parameter needs to be declared as a table.

This u can use it further in the program.

Thanks,

Rashmi.

Please check this:

data: vbeln_i type vbeln_va.

select-options: s_vbeln for (vbeln_i).

Kind Regards
