We tested using the following SELECT-SQL with different versions of Tally
Select $$FullList:FullPriceList:$Date,$$FullList:FullPriceList:$PriceLevel from StockItem where $Name='101220'
Tally 7.2 Release 3.12
The SELECT-query returned the DATE but NOT the PriceLevel.
Tally ERP 9 Release 1.61
The SELECT-query returned the both the DATE and the PriceLevel.
Remarks:-
It appears that this is an issue with Tally 7.2 Release 3.12.
