I am getting this error:
Msg 156, Level 15, State 1, Procedure WFSlaTimer, Line 144
Incorrect syntax near the keyword 'RETURN'.
Msg 178, Level 15, State 1, Procedure WFSlaTimer, Line 144
A RETURN statement with a return value cannot be used in this context.
Msg 102, Level 15, State 31, Procedure WFSlaTimer, Line 189
Incorrect syntax near 'BEGIN'.
Any help please

Answer 1

There are two kind of function that return table. the inline function and multi-statement function. Yours is multi-statement. Here is the syntax for this:
--Transact-SQL Multistatement Table-valued Function Syntax
CREATE FUNCTION [ schema_name. ] function_name
( [ { #parameter_name [ AS ] [ type_schema_name. ] parameter_data_type
[ = default ] [READONLY] }
[ ,...n ]
]
)
RETURNS #return_variable TABLE <table_type_definition>
[ WITH <function_option> [ ,...n ] ]
[ AS ]
BEGIN
function_body
RETURN
END
[ ; ]
For more information refer to CREATE FUNCTION (Transact-SQL) BOL documentation.

Answer 2

You have to define the returned table's structure (fields and data types)
1) Add a variable name to the function definition (#tableVariable in the above example).
2) Fill the table definition (columns and datatypes)
3) Modify your function to insert the result into the defined table variable, then use an empty RETURN statement when the function should return.
1st step
CREATE FUNCTION WFSlaTimer
(
#OBJECT_PK_ID INT = 110
)
RETURNS #tableVariable TABLE (
IS_SHOW_SLA INT,
StartDate DATETIME2,
EndDate DATETIME2
/** List all of your returned columns like when you creating a table **/
)
AS
BEGIN
/** Do your stuff **/
INSERT INTO #tableVariable ( /* field list */) VALUES (/* value list */)
-- OR --
INSERT INTO #tableVariable ( /* field list */)
SELECT /* FieldList */ FROM myCTE
RETURN
END
2nd step
Modify your RETURN () statement like this:
INSERT INTO #tableVanriable (IS_SHOW_SLA , StartDate , EndDate)
SELECT
IS_SHOW_SLA = CASE WHEN #TIMER_START_ACTIVITY_COMPLETED_ON IS NULL
--OR #IS_OBJECT_STATUS_IS_TERMINAL = 1
--OR #TIMER_START_ACTIVITY_COMPLETED_ON IS NULL
THEN 0
ELSE 1 END,
#START_DATE AS [START_DATE], #END_DATE AS [END_DATE],
SLA_TYPE = #SLA_DISPLAY
/** .... **/
FROM TIMER_CTE tc
/** 3rd step **/
RETURN
