Issue in passing select option as method parameter

Former Member — Mon, 30 May 2011 08:01:10 GMT

Hi,

I have written one common validation method for all select-options in selection-screen.

Which will be called for every select option validation.

I will pass s_vkorg, s_vtweg, s_abgru etc.. for each of the validations.

In the method i have created structrure & table type for the im_sel_scr_field.

This zsel_field structure is created with sign(char1), option(char2), low(45), high(45) field values.

zsel_field_tt (Table type for zsel_field structure).

Now when i am calling validation method as below, i am getting 'type compatible' error.

If i can create i.table of above structure: zsel_field i can pass the sel-opt value to i.table to avoid this error.

But i need to do this for each select option.

Z_Meth

Method

EXPORTING

im_sel_scr_field = s_vkorg[]/s_abgru[] etc...

Note: I don't want to create structure/table type for each select option.

I want to make s_vkorg[], s_abgru[] etc... passed without type-compatibale error.

Can anyone provide input for resolving this issue!

Thanks in advance.

Thanks,

Kumar.

Hi,

The structure of Sel option is as:

SIGN C(1)

OPTION C(2)

LOW C(10)

HIGH C(10)

Use the same in your method.

Hi,

Thanks for your reply.

I will get same error message 'Not Type compatible' as LOW/HIGH are Char(10) but s_vkorg will have Char4 & s_abgru will have char2.

I want to make it work for all different lengths of select options.

Thanks,

Kumar.

As each of your select options are of different type (LOW and HIGH fields) you will keep raising this error. I don't think you can statically address parameter type which would be common to all your select options. Try then working with it dynamically by passing only reference to it


"definition
METHOD z_meth IMPORTING ref_sel_opt TYPE REF TO DATA.

"implementation
METHOD z_meth.
   field-symbols: <sel> type any table, <field> type any.

   assign ref_sel_opt->* to <sel>.
   if sy-subrc = 0.
   "validate the structure
     ASSIGN COMPONENT 'SIGN' of structure <sel> to <field>.
     if sy-subrc ne 0.
         "wrong structure raise some error
     endif.
 
    ASSIGN COMPONENT 'OPTION' of structure <sel> to <field>.
     if sy-subrc ne 0.
         "wrong structure raise some error
     endif.
 
    ASSIGN COMPONENT 'LOW' of structure <sel> to <field>.
     if sy-subrc ne 0.
         "wrong structure raise some error
     endif.
 
    ASSIGN COMPONENT 'HIGH' of structure <sel> to <field>.
     if sy-subrc ne 0.
         "wrong structure raise some error
     endif. 
   endif.

   "now work with <sel> as the structure is correct
ENDMETHOD.

"client
data ref_sel type ref to data.
get reference of s_opt1[] into ref_sel.
CALL METHOD ...z_meth EXPORTING ref_sel.

get reference of s_opt2[] into ref_sel.
CALL METHOD ...z_meth EXPORTING ref_sel.

get reference of s_opt3[] into ref_sel.
CALL METHOD ...z_meth EXPORTING ref_sel.

Hi,

All of them are select options at database level.It shouldnt be a problem.Please paste teh code where you are calling the method and passing the same.Also please show the method definition.

Hi,

Thanks for your replies.

I am calling my validation code in below way currently:

DATA: gt_sel_field TYPE TABLE OF z_sel_field,

  gt_sel_field[] = s_vkorg[].

  CALL METHOD zcl_validation=>z_sel_scr_validation
    EXPORTING
*      im_param         = ''
      im_sel_field = gt_sel_field[]
*      im_sel_field = s_vkorg[].

z_sel_field is a structure with fields: sign(char1), option(char2), low(char45), high(char45).

My method (z_sel_scr_validation) in class created with below parameters:

IM_PARAM TYPE string. (optional)
IM_sel_field TYPE z_sel_field_tt, (optional)

z_sel_field_tt refers to z_sel_field structure.

In method i will validate select option (or) parameter based on user input (Have all the logic to validate against check table etc..).

In above method call i am using gt_sel_field[] but i want to use s_vkorg[], s_abgru[] etc... but they are not type compatiable

with table type (or) structure of z_sel_field. If i use gt_sel_field[] i need to declare it every time validation happens for each field.

How can i acheive this!

Thanks in advance.

Thanks,

Kumar.

Hi,

Try with below code...

select-options:

s_var1 for im_sel_scr_field,

s_var2 for im_sel_scr_field,

s_var3 for im_sel_scr_field,

s_var4 for im_sel_scr_field.

because you are maintining all select opt fields are characters. so according to that based on 'im_sel_scr_field' attribute data type we can follow to assign type to select options.

Now you can pass select option values to the respective method as well.
