Transaction with lock on a specific table NOTE : If there is similar question, please refer me to it.

I have two tables Request &amp; Receipt.

I want table Receipt remain locked for CRUD operations from anywhere until transaction finished. I need the transaction be in a Stored Procedure.

Is it impossible? How?

Why should Receipt remain locked?
Cause an internal request for insert or delete Receipt will be unable to manipulate it! Note that I need ReceiptId's be consecutive per each Request from its start, to its finish!
Use a key table to allocate receipt numbers in a way that is concurrency friendly, and still guarantees receipt numbers will never be re-used, and will (almost) never contain gaps.

I've created a minimally complete verifiable example that you could use as a basis for learning about concurrency that should set you on a good path.

Do this work in tempdb so we don't kill anything important in your actual work:

USE tempdb;


If the objects we're creating already exist, then we'll delete them first.
This allows us to easily modify the code below and re-run it multiple times
for testing.

IF OBJECT_ID(N'dbo.Requests', N'U') IS NOT NULL
BEGIN
    DROP PROCEDURE dbo.CreateRequests;
    DROP TABLE dbo.Keys;
    DROP TABLE dbo.Receipts;
    DROP TABLE dbo.Requests;
END
GO


Requests table - add columns as required:

CREATE TABLE dbo.Requests
(
    RequestID int NOT NULL IDENTITY(1,1)
        CONSTRAINT Requests_PK
        PRIMARY KEY CLUSTERED
    , RequestDate datetime NOT NULL
    , Notes nvarchar(100) NOT NULL
) ON [PRIMARY]
WITH (DATA_COMPRESSION = PAGE);


Receipts table.  ReceiptID is generated by the system, ReceiptNum is the number we'll show to users.

CREATE TABLE dbo.Receipts
(
    ReceiptID int NOT NULL IDENTITY(1,1)
        CONSTRAINT Receipt_PK
        PRIMARY KEY CLUSTERED
    , RequestID int NOT NULL
        CONSTRAINT Receipt_Request_FK
        FOREIGN KEY
        REFERENCES dbo.Requests(RequestID)
    , ReceiptNum int NOT NULL
    , ReceiptCreatedOn datetime NOT NULL
) ON [PRIMARY]
WITH (DATA_COMPRESSION = PAGE);


The Key table, where we store the most recently allocated ReceiptNum value:

CREATE TABLE dbo.Keys
(
    KeyName varchar(100) NOT NULL
        CONSTRAINT Keys_PK
        PRIMARY KEY CLUSTERED
    , LastUsedKeyValue int NOT NULL
) ON [PRIMARY];
GO


The CreateRequests stored procedure:

CREATE PROCEDURE dbo.CreateRequests
(
    @NumReceipts int = 1 /* default to 1 receipt */
    , @RequestNote nvarchar(100) = N''
    , @RequestID int OUTPUT /* this will contain the newly created RequestID */
)
AS
BEGIN
    SET NOCOUNT ON; /* prevent stored procedure from displaying "x records affected" */
    DECLARE @msg nvarchar(1000) = N''; /* used to display error messages */
    DECLARE @ret int = 0; /* stored procedure return value */
    DECLARE @LastUsedKey int;
    DECLARE @keys TABLE
    (
        KeyValue int NOT NULL
    );
    DECLARE @req TABLE 
    (
        RequestID int NOT NULL PRIMARY KEY
    );

    IF @NumReceipts &gt; 0 AND @NumReceipts &lt;= 10000 /* 10,000 is the arbitrarily chosen 
        maximum number of receipts this stored proc supports */
    BEGIN
        /* Atomically allocate @NumReceipts keys to use for Receipt Numbers */
        UPDATE dbo.Keys 
        SET LastUsedKeyValue = LastUsedKeyValue + @NumReceipts
        OUTPUT inserted.LastUsedKeyValue INTO @keys (KeyValue)
        WHERE KeyName = 'ReceiptNum';
        SELECT @LastUsedKey = k.KeyValue 
        FROM @keys k;
        IF @LastUsedKey IS NULL /* the first time we run this code, we insert a new Key */
        BEGIN
            INSERT INTO dbo.Keys (KeyName, LastUsedKeyValue)
            VALUES ('ReceiptNum', @NumReceipts)
            SET @LastUsedKey = @NumReceipts;
        END

        /* Create a new Request row, outputting the inserted RequestID 
            into a temporary table for use in the Receipts table */
        INSERT INTO dbo.Requests (RequestDate, Notes)
        OUTPUT inserted.RequestID INTO @req(RequestID)
        SELECT GETDATE(), @RequestNote;

        /* Create the new Receipts rows */
        ;WITH src AS ( /* this is configured to support a maximum of 10,000 new receipts */
            SELECT TOP(@NumReceipts) 
                ReceiptNum = (v5.Num + (v4.Num * 10) + (v3.Num * 100) + (v2.Num * 1000) 
                     + (v1.Num * 10000)) + 1 + (@LastUsedKey - @NumReceipts)
            FROM (VALUES (0), (1), (2), (3), (4), (5), (6), (7), (8), (9)) v1(Num)

        INSERT INTO dbo.Receipts (RequestID, ReceiptNum, ReceiptCreatedOn)
        SELECT r.RequestID, ReceiptNum, GETDATE()
        FROM @req r

Here, we add three different requests, with a varying number of receipts to show the functionality of the stored procedure:

DECLARE @ReqID int;
DECLARE @ReturnValue int;
EXEC @ReturnValue = dbo.CreateRequests @NumReceipts = 19
    , @RequestNote = N'Test Request #1'
    , @RequestID = @ReqID OUT
SELECT ReturnValue = @ReturnValue, ReqID = @ReqID;
SELECT *
FROM dbo.Receipts rec
WHERE rec.RequestID = @ReqID;

To verify concurrency, and that the allocation of Receipt Numbers is reliable, I ran the following code simultaneously in three separate SSMS windows, creating nearly 30,000 receipts:

DECLARE @note nvarchar(100);
DECLARE @ReqID int;
DECLARE @ReturnValue int;
DECLARE @loop int = 1;
DECLARE @maxloops int = 1000;
WHILE @loop &lt; @maxloops
BEGIN
    SET @note = N'Concurrency request loop ' + CONVERT(nvarchar(10), @loop);
    EXEC @ReturnValue = dbo.CreateRequests @NumReceipts = 5
        , @RequestNote = @note
        , @RequestID = @ReqID OUT;
    SET @loop += 1;
END;
