Performance issues in select from table HRV1222A

Hi all,

We have a custom FM with this select in the code:

SELECT otype objid         FROM hrv1222a         INTO TABLE lt_hrv1222a         WHERE plvar EQ '01'           AND begda LE sy-datum           AND endda GE sy-datum           AND istat EQ '1'           AND attrib EQ lv_attrib
 AND low EQ lv_value.

We use this FM a lot of times and we're having a lot of performance problems due this select.

Do you know how can I improve this code?
Is there any FM to get the data we want without doing a select to this table? Actually it is a view of two tables.

May be we need to create secondary indexes to the tables of the view...

Thanks in advance,

Regards,
Ricardo.
