Handling data refresh by HASHLOV

[Jaimini Bhatt]

Hello we are going to have a regular weekly/monthly data refresh. In such case, the total number of rows in many tables may vary. How does TDM handle the refresh especially in case of HashLOV.  where the seed file will remain static in its size and the target tables may have a different number of records? 

Can HashLOV deliver consistent masking for the same ID irrespective of total size of data?

Hi Jaimini,
       If there is frequent data refresh, If you apply masking function HASHLOV on refreshed data, complete data will be masked again and generate new data. Which mean, it does not maintain same masking values as in previous run. Hope you are clarified with this answer. As we have a call scheduled tomorrow, we will discuss in detailed if you have any further questions.

Thanks,
Srikanth
