How to access Temp Table in the stored procedure which is created in another stored procedure?

Building on Damien comments..

The table can be referenced by any nested stored procedures executed by the stored procedure that created the table

create proc usp_innertest1
as 
begin
select n as innertest1 from #test
end

create proc usp_innertest2
as 
begin
select n as innertest2 from #test
end


create proc dbo.test
as
begin
select top 1* into #test from numbers
exec usp_innertest1
exec usp_innertest2
end

now Executing test gives

innertest1 

1

innertest2

1

The table cannot be referenced by the process which called the stored procedure that created the table

this is obvious,if usp_innertest1 creates a temp table,it can't be accessed by test(main calling process)

There are also global temporary tables which reside till all the references are closed

---connection1

select top 1 * into ##test from numbers


--now open new connection(connection 2) and do below

begin tran

update ##test
set id=1

--now close connection1

-- now go to connection 2
select * from ##test

you can access this table until you committed it
