Hi  NewbieJono ,

Here are the steps you can follow：

1. Create calculated table.

Table =
var _table1=
SUMMARIZE(
'Table1',Table1[Date],"Value",SUMX(FILTER(ALL(Table1),YEAR('Table1'[Date])=YEAR(EARLIER('Table1'[Date]))&&MONTH('Table1'[Date])=MONTH(EARLIER('Table1'[Date]))),[Value1]),"Table","Table1")
    var _table2=
SUMMARIZE(
'Table2',Table2[Date],"Value",SUMX(FILTER(ALL(Table2),YEAR('Table2'[Date])=YEAR(EARLIER('Table2'[Date]))&&MONTH('Table2'[Date])=MONTH(EARLIER('Table2'[Date]))),[Value2]),"Table","Table2")
var _table3=
UNION(_table1,_table2)
var _table4=
FILTER(
    _table3,
   [Value]=MAXX(FILTER(_table3,[Table]=EARLIER([Table])&&YEAR([Date])=YEAR(EARLIER([Date]))),[Value]))
return
_table4

2. Create measure.

Flag =
var _column1=SELECTCOLUMNS(FILTER('Table','Table'[Table]="Table1"),"1",[Date])
var _column2=SELECTCOLUMNS(FILTER('Table','Table'[Table]="Table2"),"2",[Date])
return
    IF(
    NOT(MAX('Table2'[Date])) in _column2,1,
    IF(
    NOT(MAX('Table1'[Date])) in _column1 ,0,1)
)

3. Set [Flag] to is=1 in Table 1 and set [Flag] to is=0 in Table2.

4. Result:
