Splitting rows by csv value in a column

$

Hello Gurus, I have a table in HANA containing a column with CSV value for each row. Some of these values are valid and some are dummy.  Using a list of valid values (can create a table in HANA to contain these values) we want to break each row of data and ignore dummy values. In the example below “D” is the dummy value.

As is View.

Volume of data is 6m rows, valid values are around 70 (this will increase in the future). Please suggest a solution by which we can create another table within Hana to be used for Analytical and Calculation views. Or can there be an option to compute these rows on the fly using a View itself?Solution has to be within HANA as transformation using BODS isn’t an option. Thanks
