Probably, what you are looking for is how to debug an SQL function.

OriginalGriff has mentioned a nice link.

but I think you want to check you SP in parts in SSMS.(Not in your code) like "exec spname"

so you can use return for this purpose.

ALTER FUNCTION [dbo].[islistthere]
(
	@ent	char(4), 	@Id int, @month char(4), @sec int
)
RETURNS char(5)  AS
BEGIN
	DECLARE @Table1 int
	DECLARE @Table2 int
	DECLARE @Add char(5)
	SET @Add = 'false'
 
	SET @Table1 = ( SELECT COUNT(PRID) FROM PR WHERE PRID = @Id and ent = ltrim(rtrim(@ent)) and TMonth=@month)

select @Table1
return -- it will return from here and would not execute other statements

	SET @Table2 = ( SELECT COUNT(PRDID) FROM PRD WHERE PRID = @Id andent = ltrim(rtrim(@ent)) and TMonth=@month and TSec=@sec)
 
	IF (@sec = 0 AND @Table1 = 0 )
		SET @Add = 'true'	
 
 
	IF (@sec > 0 AND @Table1 = 1 AND @Table2 = 0 )
		SET @Add = 'true'
	
 
	
	
		
	RETURN @Add 
END

but once you done with checking don't forget to remove these extra "return" from your sp, Otherwise it will give error/wrong output.
