Dynamic loop condtions

Hi All,

i have 2 internal tables, 1 is coming from ECC and the other is coming from Flatfile upload with similar structure, i need to compare these two fields based on the Key if key field matches then i need to delete the corresponding record of 2nd internal table.

challenges i am facing are

1. these 2 internal tables are dynamic

2. i am creating a 3 rd internal table to fetch the Key fields of ECC table from DD03L table

3. i need to loop on the 1st internal table and delete the records of 2nd internal table.

please help how to proceed
