How to delete the unused Pricelevels ?

Dear sir

im used many price levels , but some price levels are not in use so how to delete this ?

thanks for ur advice

 

Hi Any Master Level field which are used cannot be deleted . May be u can hide from display by writing some TDL

 

Thanks for ur response sir ,
i think pricelevel stored in stockitem masters,
and I have too many price levels and above 100 Stockitem in my data,
also i split data to next year unused pricelevels also coming, so data will be slow .
so is there any chance to delete unused pricelevel in stockitem master ?

 

Please mention the code to hide unused ledger from table
