Request to query past security master

Hi, I would like to make a request to query both compact & detailed security master by date(upto a month or two). It has recently come to my knowledge that the detailed one had issues with missing indices on detailed security master which is causing me issues in backtesting as it was highly dependent on security master for getting the symbols. Also, I didn’t stored the compact one as detailed had more information which I might have used later.
