Move data from inertal table to other internal table with keys

Hello gurus, I have 2 internal table: IT_ALV and IT_ALV2 in IT_ALV I have some data that I want to move to IT_ALV2, I have key in IT_ALV and IT_ALV2 to do the match. please see images below: IT_ALV:

IT_ALV2:

As you can see I have same keys in two tables, with this I could select the value from it_alv and insert in it_alv2 with the key to insert this row in the correct line, but I dont know how can I do this.

Could anyone please help me?
