SELECT does not return rows when queried by VBELN

Question

I'm trying to display table in alv from an internal table where rows are added form a table stored in the database. Without a where condition I see rows displayed in alv but with a where condition in the select statement no rows are returned.

Here is the code:

REPORT  ZSAM.

DATA: IT_1 TYPE STANDARD TABLE OF VBAK.

select vbeln audat netwr waerk vkorg vtweg 
    from VBAK 
    into corresponding fields of Table IT_1 
    where vbeln > 4500 
      and vbeln < 6000.

Any idea why using where condition makes it not return any rows and how to fix?

vbeln是一个具有十个位置的字段，并使用ALPHA转换例程（请参见数据元素后面的域）。这意味着该值将填充前导零（只要它仅包含数字）。由于这是字符类型字段，因此还必须使用撇号进行比较。因此，WHERE条件必须是这样的：

WHERE vbeln GT '0000004500'
  AND vbeln LT '0000006000'
