Hi,

Simply check the fields whether they are populated or not and build the where clause.

see the following example:

data : begin of itab occurs 0,
         matnr like mara-matnr,
end of itab.

ypes: begin of ty_s_clause.
types:   line(72)  type c.
types: end of ty_s_clause.

data : begin of gt_condtab occurs 0.
        include structure hrcond.
data : end   of gt_condtab.

FIELD-SYMBOLS <fs_wherecond> TYPE ty_s_clause.
data:
  gt_where_clauses  type standard table of ty_s_clause
                    with default key.


gt_condtab-field = 'MATNR'.
gt_condtab-opera = 'EQ'.
gt_condtab-low = '000000000000000111'.
append  gt_condtab.
clear  gt_condtab.

call function 'RH_DYNAMIC_WHERE_BUILD'
  exporting
    dbtable         = space " can be empty
  tables
    condtab         = gt_condtab
    where_clause    = gt_where_clauses
  exceptions
    empty_condtab   = 01
    no_db_field     = 02
    unknown_db      = 03
    wrong_condition = 04.
            .
 
select matnr from mara into table itab where (gt_where_clauses).

We can use a simple STRING concatenated also. Example:

DATA : l_where TYPE string,
       i_marc TYPE STANDARD TABLE OF marc.

CONSTANTS: l_quote TYPE char1 VALUE ''''.

PARAMETERS : p_plant TYPE marc-werks.

CONCATENATE 'WERKS' space '=' space l_quote p_plant l_quote space
            'AND' space 'PERKZ' space '=' space l_quote 'M' l_quote
       INTO l_where RESPECTING BLANKS.

SELECT * FROM marc INTO TABLE i_marc WHERE (l_where).

Hello,

Are the screen elements PARAMETERS or SELECT-OPTIONS?

If they are all SELECT-OPTIONS you can use all the elements in the WHERE clause of the SELECT statement e.g.,

SELECT field1 field2 field3
FROM dbtable
INTO TABLE itab
WHERE
field1 = s_elem1 AND
field2 = s_elem2 AND
field3 = s_elem3 .... so on & so forth

BR,

I also have a strange feeling that the IN operator has been re-invented in this thread...just slightly more complicated.
