ROWID in Where clause

Question

Hello All,
I have table with 25 columns.
First three columns are composite keys
1. ID, . STORE_NUM, 3. STORE_NUM_WEEK
to update data i have to use all three column in WHERE clause for proper update. So in cursor also i have to select all three rows., Instead i SELECTED ROWID in cursor and used in where caluse in BULK COLLECT and FORALL update. instead of fetching all three rows. IS this the correct approch. WIth ROWID in don't have to use HINTs and the query and updation runs faster then the other( without ROWID).
I was reading on the intenet some where that using ROWID in not advisible in query.
How correct it is in my case.
Please clearify my daughts.
Thank you in Advance

Thank you sundar for your response.
Please look at my procedure. as under . I am posting the same for your consideration. It is updating selective rows only not all rows. As suggested. How can I do in SQL what about the formula to calculate the value to update.
Please ignore the syntex but look ate code and if you have any suggestion.Sorry for BIG CODE Procedure SP_930_End_Of_Week_OH_up (
