Using a Conversion Table

*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?*
