Using a Conversion Table

[Anthony Apollis <anthony.apollis@xxxxxxxxx>]

I am trying to convert a column from ZAR Column " Amount_in_Company_Code_Currency"  " to USD.

 Table:

CREATE TABLE IF NOT EXISTS system."IMETA_ZTRB_MP$F_ZTBR_TA_BW2"
(
    "Company_Code" character varying(255) COLLATE pg_catalog."default",
    "Posting_Period" integer,
    "Fiscal_Year" integer,
    "Profit_Center" character varying(255) COLLATE pg_catalog."default",
    "Account_Number" integer,
    "Business_Process" character varying(255) COLLATE pg_catalog."default",
    "Internal_Order" character varying(255) COLLATE pg_catalog."default",
    "Amount_in_Company_Code_Currency" numeric,
    "Company_Code_Currency" character varying(255) COLLATE pg_catalog."default",
    "BRACS_FA" character varying(255) COLLATE pg_catalog."default",
    "Expense_Type" character varying(255) COLLATE pg_catalog."default",
    "BRACS_ACCT_Key" character varying(255) COLLATE pg_catalog."default",
    "Segment_PC" character varying(255) COLLATE pg_catalog."default",
    "CC_Master_FA" character varying(255) COLLATE pg_catalog."default",
    "Loaddate" date DEFAULT CURRENT_DATE,
    "Row_Hash" text COLLATE pg_catalog."default",
    "LoadTime" timestamp without time zone DEFAULT CURRENT_TIMESTAMP,
    "ZTBR_TransactionCode" integer NOT NULL GENERATED ALWAYS AS IDENTITY ( INCREMENT 1 START 1 MINVALUE 1 MAXVALUE 2147483647 CACHE 1 ),
    CONSTRAINT "IMETA_ZTRB_MP$F_ZTBR_TA_BW_pkey2" PRIMARY KEY ("ZTBR_TransactionCode")
)

Conversion Table :

CREATE TABLE IF NOT EXISTS dim."IMETA_Master_Currency_Data_TA_BR"
(
    "Currency" character varying(255) COLLATE pg_catalog."default",
    "Currency name" character varying(255) COLLATE pg_catalog."default",
    "Currency from" character varying(255) COLLATE pg_catalog."default",
    "Scenario" character varying(255) COLLATE pg_catalog."default",
    "Fiscal year" double precision,
    "Fiscal period" character varying(255) COLLATE pg_catalog."default",
    "Currency from value" double precision,
    "Currency to value" double precision,
    "Loaddate" date
)

TABLESPACE pg_default;

I am getting no output for using:

SELECT
    z."Fiscal_Year",
    SUM(z."Amount_in_Company_Code_Currency") AS Total_Amount,
    ROUND(SUM(z."Amount_in_Company_Code_Currency" / CASE
        WHEN c."Currency" = 'USD' THEN 1
        ELSE c."Currency to value" END)::numeric, 2) AS Total_Amount_USD
FROM
    system."IMETA_ZTRB_MP$F_ZTBR_TA_BW2" z
LEFT JOIN
    (SELECT
        "Currency",
        "Currency to value"
     FROM
        dim."IMETA_Master_Currency_Data_TA_BR"
     WHERE
        "Scenario" = 'Actual'  -- Adjust the scenario as needed
        AND "Fiscal year" = 2024) c  -- Adjust the fiscal year as needed
ON
    z."Company_Code_Currency" = c."Currency"
WHERE
    z."Fiscal_Year" = 2024
GROUP BY
    z."Fiscal_Year";

In a previous calculation/join i used the code below and it worked, what am i doing wrong?
