Please assist. I have developed an ETL, using these codes to get data from the source and to the destination:
This table did not have a primary key and secondary keys with unique values. I brought it in:
-- Table: system.IMETA_ZTRB_MP$F_ZTBR_TA_BW
-- DROP TABLE IF EXISTS system."IMETA_ZTRB_MP$F_ZTBR_TA_BW";
CREATE TABLE IF NOT EXISTS system."IMETA_ZTRB_MP$F_ZTBR_TA_BW"
(
"ZTBR_TransactionCode" integer NOT NULL DEFAULT nextval('system."ZTBR_Query_Destination_ZTBR_TransactionCode_seq"'::regclass),
"Company_Code" character varying(4) COLLATE pg_catalog."default",
"Posting_Period" character varying(7) COLLATE pg_catalog."default",
"Fiscal_Year" character varying(4) COLLATE pg_catalog."default",
"Profit_Center" character varying(255) COLLATE pg_catalog."default",
"Account_Number" character varying(255) COLLATE pg_catalog."default",
"Business_Process" character varying(255) COLLATE pg_catalog."default",
"Cost_Center" character varying(10) COLLATE pg_catalog."default",
"Internal_Order" character varying(255) COLLATE pg_catalog."default",
"Trading_Partner" character varying(255) COLLATE pg_catalog."default",
"Amount_in_company_code_currency" numeric(17,2),
"Company_code_currency" character varying(5) 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",
"CC_Direct" 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",
"Master_BRACS_Secondary_Key" integer,
"Source_Description_Secondary_Key" integer,
"Direct_Indirect_Secondary_Key" integer,
"Entity_Secondary_Key" integer,
"Region_Secondary_Key" integer,
"RowInsertedTimestamp" date DEFAULT CURRENT_DATE,
"RowUpdatedTimestamp" timestamp DEFAULT CURRENT_TIMESTAMP,
CONSTRAINT "ZTBR_Query_Destination_pkey" PRIMARY KEY ("ZTBR_TransactionCode"),
CONSTRAINT fk_direct_indirect FOREIGN KEY ("Direct_Indirect_Secondary_Key")
REFERENCES dim."IMETA_Direct_Indirect_Mapping" ("Direct_Secondary_Key") MATCH SIMPLE
ON UPDATE NO ACTION
ON DELETE NO ACTION,
CONSTRAINT fk_entity FOREIGN KEY ("Entity_Secondary_Key")
REFERENCES dim."IMETA_Entity_Mapping" ("Entity_Secondary_Key") MATCH SIMPLE
ON UPDATE NO ACTION
ON DELETE NO ACTION,
CONSTRAINT fk_master_bracs FOREIGN KEY ("Master_BRACS_Secondary_Key")
REFERENCES dim."IMETA_Master_BRACS_to_SAP_Data_TA_BR_" ("ZTBR_TransactionCode") MATCH SIMPLE
ON UPDATE NO ACTION
ON DELETE NO ACTION,
CONSTRAINT fk_source_description FOREIGN KEY ("Source_Description_Secondary_Key")
REFERENCES dim."IMETA_Source_Description_Mapping" ("BRACS_Key") MATCH SIMPLE
ON UPDATE NO ACTION
ON DELETE NO ACTION
)
TABLESPACE pg_default;
I want to use SSIS to bring in values starting from 1:
"Master_BRACS_Secondary_Key" integer,
"Source_Description_Secondary_Key" integer,
"Direct_Indirect_Secondary_Key" integer,
"Entity_Secondary_Key" integer,
"Region_Secondary_Key" integer,
These columns contain NULLS and when I try to amend it so that it can start from 1, my ETL fails because of a secondary key violation.
This insert produce no data in table because of the secondary keys containing nulls.
- Check if the table already exists

Im trying the Script task, but I'm getting errors:

Ideally, all of your DDL should be happening outside of SSIS. Can't tell whether this is the case here.
Use derived columns within your SSIS data flow to populate the non-nullable columns. Or modify your source query (depending on the source).
The absence of evidence is not evidence of absence

The absence of consumable DDL, sample data and desired results is, however, evidence of the absence of my response
