Differrance betwee two values in rows

hello Anonymous 

I think there are some misunderstandings. Tried to figure out a solution for you. Please check if the concept of this codes works for you.

let
	TableA = #table
	(
		{"Object","Max Allowed"},
		{
			{"A","15"},	{"B","10"},	{"C","10"},	{"D","5"}
		}
	),
    ChangedTypeA = Table.TransformColumnTypes(TableA,{{"Max Allowed", Int64.Type}}),
    TableB = #table
	(
		{"Object","Times"},
		{
			{"A","1"},	{"B","1"},	{"C","1"},	{"D","1"},	{"A","1"},	{"B","1"},	{"C","1"},	{"D","1"},	{"A","1"},	{"B","1"},	{"C","1"},	{"D","1"},	{"A","1"},	{"B","1"},	
			{"C","1"},	{"D","1"},	{"A","2"},	{"B","3"},	{"C","4"},	{"D","5"},	{"A","6"},	{"A","7"},	{"A","8"},	{"B","9"},	{"B","10"},	{"D","11"},	{"D","12"},	{"D","13"},	
			{"D","14"}
		}
	),
    ChangedTypeB = Table.TransformColumnTypes(TableB,{{"Times", Int64.Type}}),
    JoinTables = Table.NestedJoin
    (
        ChangedTypeA,
        "Object",
        ChangedTypeB,
        "Object",
        "Times"
    ),
    CountRowTimes = Table.AggregateTableColumn(JoinTables, "Times", {{"Times", List.Count, "Count of Times"}}),
    AddCheck = Table.AddColumn(CountRowTimes, "Check", each if [Count of Times]>[Max Allowed] then "check" else "not check")

in
	AddCheck
