Hi Sandesh..
Try This
Create this view as PO
SELECT count(t1.docentry) as Count,cardcode
                 FROM   odrf t1
       INNER JOIN drf1 t2 ON  t1.docentry = t2.docentry and t2.ObjType='22' where t1.docstatus='O'
        group by  cardcode
Use this tnsp for the block
  IF @object_type = '112'
         AND @transaction_type IN ('A', 'u')
      BEGIN
          IF EXISTS(
SELECT t1.docentry
                 FROM   odrf t1
       INNER JOIN drf1 t2
                             ON  t1.docentry = t2.docentry and t2.ObjType='22'
                             inner join PO t3 on t3.cardcode=t1.CardCode
                 WHERE  @list_of_cols_val_tab_del = t1.docentry and t3.count>'6'
          BEGIN
              SET @error = -1
              SET @error_message ='You Cannot Perfrom this Action pending purchase order'
          END
      END
