row level restriction implementation

Hello ,

I have a below scnerios for which I need to implement a row level security in universe.

We have different security type like customer, region, products etc. at any moment the restrcition should be applied only as desired. For ex if a user is restrcited to a specifc customer and a region then he should see only those customer and region details

We have a security table which looks like below

Username     Customer            Region

Laxmi           ABC                        Korea

Laxmi          XYZ                         China      

Laxmi                                            India

When user Laxmi logs in he should only see the below data..

ABC customer for Korea region,for China region only XYZ customer and all customer for India Region.

Thanks,

laxmi
