Hi Guys,
I need to create a report which will extract all the inactive customers.My criteria for selection is "A customer will inactive if there has been no sales activity for more than 18 months and no open items exist."Now as I am from ABAP background I am unable to get what is the logic to achive the requirement.
Please help me on this!

Hi Ronit,
You could use some code like this:
TYPES:
   BEGIN OF ty_data,
     kunnr TYPE kunnr,
     last_date TYPE budat,
   END OF ty_data.
PARAMETERS:
   p_cutoff TYPE dats.
DATA:
   lt_with_open TYPE HASHED TABLE OF kunnr WITH UNIQUE KEY table_line,
   lt_data TYPE STANDARD TABLE OF ty_data.
FIELD-SYMBOLS:
   <data> TYPE ty_data.
* Customers whose last sales order is older than cutoff:
SELECT kunnr MAX( erdat ) INTO TABLE lt_data
        FROM vbak
        GROUP BY kunnr
        HAVING MAX( erdat ) < p_cutoff.
* Which of those customers have any open items:
SELECT DISTINCT kunnr INTO TABLE lt_with_open
        FROM bsid
        FOR ALL ENTRIES IN lt_data
        WHERE kunnr = lt_data-kunnr.
LOOP AT lt_data ASSIGNING <data>.
   READ TABLE lt_with_open TRANSPORTING NO FIELDS
        WITH TABLE KEY table_line = <data>-kunnr.
   IF sy-subrc <> 0.
     WRITE: / 'Customer', <data>-kunnr.
   ENDIF.
ENDLOOP.
