How to create new records and append them in result package?

Hello Experts,

I have a requirement like this:

1.Firstly we will be having a record(marked in blue) like this in result package.

2.Then based on the Range From and Range To values we need to look up values which lies with that range from q-table of master data 0COSTELMNT.

3.If record is found append the same as new records(marked in red) in the same result package.

I have created an internal table all the data of q-table.Now how can we compare the stored values of internal table which lies in between Range From and Range To of result package  and populate the same as new records in the same result package?

Please help.

Thanks and Regards,

Soumya Roy.
