Pl/sql Fuction Output

Question

Hi,
The given below function used in a formula column of report 6i and its return value used to display iterm_code description in a quotation. But for corresponding to some values(V_segment6) the o/p is giving wrong answer.
i cant find where the problem lies.

====================================
The O/p of the query for segment1 to segment6
SELECT segment1||'_'||segment2||'_'||segment3||'_'||segment4||'_'||segment5||'_'||segment6 item_code
FROM MTL_SYSTEM_ITEMS
WHERE INVENTORY_ITEM_ID in (25223,25219,25221,25215,25213)
1_HR_038000_12190_000000_00000
1_HR_038000_15000_000000_00000
1_HR_038000_15000_000000_00000
1_HR_048000_15000_000000_00000
1_HR_058000_12190_000000_00000
here the segment6 is 00000. but the function returns (v_desc) following values:
HR Thick 5.8mm Wid 1500mm Len 1500mm
HR Thick 4.8mm Wid 1500mm Len 1500mm
HR Thick 5.8mm Wid 1219mm Len 1219mm
HR Thick 3.8mm Wid 1500mm Len 1500mm
HR Thick 3.8mm Wid 1219mm Len 1219mm
Actually there is no need of "Len 1500mm" and " Len 1219mm" in the above O/p.
since segment6 is '00000'. Why it is giving this O/P?

Answer 1

Actually there is no need of "Len 1500mm" and " Len 1219mm" in the above O/p.
since segment6 is '00000'. Why it is giving this O/P? Because you have the last V_DESC:=V_DESC||' Len '||V_TEMP; outside the if statement

you might try
function CF_ITEM_DESCRIPTIONFormula return Char is
  v_segment2 varchar2(150); --type
  v_segment3 varchar2(150); --thick
  v_segment4 varchar2(150); --wid
  v_segment5 varchar2(150); --size
  v_segment6 varchar2(150); --len
  v_desc varchar2(2000);
begin
  SELECT segment2,segment3,segment4,segment5,segment6
    into v_segment2,v_segment3,v_segment4,v_segment5,v_segment6
    FROM MTL_SYSTEM_ITEMS
   WHERE INVENTORY_ITEM_ID = INVENTORY_ITEM_ID
     AND ORGANIZATION_ID = 81;
  select case when b.flex_value_set_id = 1006715
               and b.flex_value = v_segment2
              then a.flex_value_meaning
         end ||
         case when b.flex_value_set_id = 1006716
               and b.flex_value = v_segment3
               and v.segment3 != '000000'
              then ' Thick ' || a.description
         end ||
         case when b.flex_value_set_id = 1006717
               and b.flex_value = v_segment4
               and v.segment4 != '00000'
               and v.segment2 != 'PP'
              then ' Wid ' || a.description
         end ||
         case when b.flex_value_set_id = 1006718
               and b.flex_value = v_segment5

         end ||
         case when b.flex_value_set_id = 1006719
               and b.flex_value = v_segment6
               and v.segment6 != '00000'
              then ' Len ' || a.description
         end
    into v_desc
