Help

The problem I’m having

I have created a snapshot model. which looks fine. But I need to create another snapshot based on snapshot Already I have created, Question is can I do this, If I do is there any chance to be created duplicate surrogate key or not

The context of why I’m trying to do this

My initial snapshot working fine, I need to create a snapshot model based of category

What I’ve already tried

Already I have created first my snapshot “dim_invoicelinetext” and I have used that snapshot in the current snapshot "dim_invoiceline_category " - My query Is there any chance to be generate duplicate surrogate key in "dim_invoiceline_category "

Some example code or error messages

{% snapshot dim_invoiceline_category %}

  {{
    config(
      target_schema=env_var('TARGET_SCHEMA'),
      strategy='check',
      unique_key='billlineid',
      check_cols=[
        'invoicelinecategory',
      ],
    )
  }}

select {{ dbt_utils.generate_surrogate_key([

    'billlineid',
    'invoicelinecategory']) }}
as invoiceline_category_key,

        billlineid, 
        invoicelinecategory
from (

        SELECT  
        billlineid  :: int as billlineid,
        (
            CASE

                WHEN item ='Reverse RO in Unit Rate'    AND pricename = 'Reverse RO in Unit Rate' THEN 'Renewables Obligation (RO)'
                WHEN item = 'Reverse BSUoS in Unit Rate'  AND pricename = 'Reverse BSUoS in Unit Rate'    THEN 'Balancing Services Use of System (BSUoS)'
                ELSE pricename
            END
        ) :: varchar(255) as "invoicelinecategory"

    FROM

        {{ ref('dim_invoicelinetext') }} ) as dim_invoiceline_category

{% endsnapshot %}```
