Spring Batch - org.springframework.dao.DeadlockLoserDataAccessException in Azure SQL Server?

I have a spring batch application that uses Azure SQL Server as a database.

The Source table has two entries for the combination of each Store [0001] Eff_Date [2021-10-29] and ItemID [0000000000000]

Something like

Store [0001] Eff_Date [2021-10-29] and ItemID [0000000000000]
Store [0001] Eff_Date [2021-10-29] and ItemID [0000000000000]

Store [0002] Eff_Date [2021-10-29] and ItemID [0000000000000]
Store [0002] Eff_Date [2021-10-29] and ItemID [0000000000000]

The target table has a cluster primary key constraint as Store + Eff_Date + ItemID.

The application is designed is such a way

  1. Insert the Record
  2. If Insert fails, update the Record

I was getting the following error while trying to process the above records

2021-12-15 03:42:51,134 DEBUG [SimpleAsyncTaskExecutor-1] ItemItemWriter - Writing record for [0001] Eff_Date [2021-10-29] Host Batch [0] UPC [0000000000000]

2021-12-15 03:42:52,546 ERROR [SimpleAsyncTaskExecutor-1] ItemDaoImpl - An error occurred during item update for Item [0000000000000] ] Store [0001] ] Batch [0] ] Date [2021-10-29] :org.springframework.dao.DeadlockLoserDataAccessException:

Most of the update fails with DeadlockLoserDataAccessException.

So, I have updated the Insert & Update statement like (with and without Begin Tran & commit Tran, result is same)

  1. Begin Tran Insert into Table with (Tablock)... Commit tran
  2. Begin Tran Update Table with (Tablock) set commit Tran

also tried(with and without Begin Tran & commit Tran, result is same):

  1. Begin Tran Insert into Table with (SERIALIZABLE)... Commit tran
  2. Begin Tran Update Table with (SERIALIZABLE) set commit Tran

Now update statement no longer fails with DeadlockLoserDataAccessException however few of the insert statement throws the DeadlockLoserDataAccessException exception

What could be the reason and fix?

Note: I tried removing with (tablock) from the insert statement but update statement starts throwing the deadlock errors.

Note: I have appended my JDBC URL with sendStringParametersAsUnicode=false

I verified the table and found only char, varchar, int & Datetime2 columns.

Also jdbctemplate.update takes query, values and the datatype. Datatype is properly defined in the application. No reference of nvarchar found anywhere in the application.
