How to select the beginning of a period in a query if the date has a composite data type?

Question

1C

In the query it is necessary to group the data by months, to get the month I use the query language function "START OF THE PERIOD", but the compiler does not skip such a query because I'm getting the date from a register property, which has a composite data type. Can I somehow get around this limitation?

If Express(BT_QueryDate As Date) doesn't help, then nothing. But in general, it is strange to shove something other than the date into the field named Date. Why is this done?
