Create multiple ranges dynamically with unique name

[Former Member]

Hi Friends,

i have a requirement to create a program to select data from table. User will maintain the condition (i.e. where) to be applied in select statement in a database table.

Select * from (Table) into <target Table> where (lc_where).

In order to create the dynamic where clause, i need to create dynamic range table with unique name and populate the condtion.

WHERE COMPCODE  IN <FS_COMPCODE>

     AND INVOICENO    IN <FS_INVOICENO>

     AND FISCALYEAR IN <FS_FISCALYEAR>

Plese let me know how we can address this requirement.

Regards

Suresh Kumar

Hi Suresh,

You could write a subroutine or a macro to build the range tables. I've often used macros for this though a subroutine would achieve the same result...

*&---------------------------------------------------------------------*
 *&      Macro  APPEND_RANGE
 *&---------------------------------------------------------------------*
 *       Using sign and option from &1, appends low value &2 to range
 *       table &4 via intermediate structure &3.
 *----------------------------------------------------------------------*
define append_range.
 
   if not &2 is initial.
     concatenate &1 &2 into &3.
     append &3 to &4.
   endif.
 
 end-of-definition.

Then elsewhere in the code you can call the macro. I often use this approach to add multiple LOW values to the same range...

   append_range 'IEQ' lv_value_type_1 ls_r_wrttp lr_wrttp.
   append_range 'IEQ' lv_value_type_2 ls_r_wrttp lr_wrttp.
   append_range 'IEQ' lv_value_type_3 ls_r_wrttp lr_wrttp.

But you could also use the approach to build different ranges...

   append_range 'IEQ'  low_value_1  ls_structure_1  lr_range_1.
   append_range 'IEQ'  low_value_2  ls_structure_2  lr_range_2.
   append_range 'IEQ'  low_value_3  ls_structure_3  lr_range_3.

It occurs to me though that if you're storing selection conditions in a database table anyway, why not use table TVARVC (maintained through transaction STVARV) to store the ranges? Instead of using a custom database table to store these conditions, create the ranges in TVARVC as Selection Options and use them directly in your SQL queries.

Cheers,

Amy

Hi Suresh ,

You can declare three data structures with  TYPE RANGE OF declaration for your requirement.

Say for eg:

DATA :  R_ COMPCODE TYPE RANGE OF BUKRS WITH HEADER LINE ,

             R_INVOICENO TYPE RANGE OF BELNR_D WITH HEADER LINE,

             FISCALYEAR TYPE RANGE OF GJAHR WITH HEADER LINE.

And you can fill these ranges as per requirement , like as follows

REFRESH : R_COMPCODE.

CLEAR : R_COMPCODE.

R_COMPCODE-SIGN = 'I'.

R_COMPCODE-OPTION = 'EQ'

R_COMPCODE-LOW = '1000'.    "these values can be hard coded or selected from other structures as well

APPEND R_COMPCODE.

Similarly you can carry on with other range variables also.. and after that use in the where clause like a select-option variable

eg:

WHERE COMPCODE  IN R_COMPCODE

     AND INVOICENO    IN R_INVOICENO

     AND FISCALYEAR IN R_FISCALYEAR
