Corrupt POs And Receipts In Both Work and Open

I had a client report a problem with a couple of purchase orders which were showing in the PO Entry window, but which they could not open. While looking into the problem we found three things:

1. The problem was down to corruption where the PO was on both the work and open tables;
2. There was more than just two POs;
3. The problem also affected receipts.

Rather than trying to identify the problems manually, I wrote a SQL script which would identify all POs and Receipts which were on both the Work and Open tables:

CREATE TABLE #POCHECK(
	PONUMBER VARCHAR(20)
	,POPRCTNM VARCHAR(20)
	,CHCKDGIT INT
	,DCSTATUS INT
)
GO

INSERT INTO #POCHECK
	(PONUMBER,POPRCTNM,CHCKDGIT,DCSTATUS)
--VALUES
	(SELECT PONUMBER,'',1,1 FROM POP10100)
GO

INSERT INTO #POCHECK
	(PONUMBER,POPRCTNM,CHCKDGIT,DCSTATUS)
--VALUES
	(SELECT PONUMBER,'',1,3 FROM POP30100)
GO

INSERT INTO #POCHECK
	(PONUMBER,POPRCTNM,CHCKDGIT,DCSTATUS)
--VALUES
	(SELECT '',POPRCTNM,1,1 FROM POP10300)
GO

INSERT INTO #POCHECK
	(PONUMBER,POPRCTNM,CHCKDGIT,DCSTATUS)
--VALUES
	(SELECT '',POPRCTNM,1,3 FROM POP30300)
GO

SELECT
	PONUMBER
	,POPRCTNM
	,SUM(CHCKDGIT) AS DCCOUNT
FROM
	#POCHECK
GROUP BY
	PONUMBER,POPRCTNM
HAVING
	SUM(CHCKDGIT) > 1
GO

DROP TABLE #POCHECK
GO

After we used the script to identify the corrupt orders, it was a case of going through the returned records and correcting errors.
