Letter Generation Error



We had an error with the 3CEngine the other day.  Here is the error and the fix in case it helps anyone else or in case I have this same problem later on.

From the Application Engine Output:

File: e:pt84912b-retailpeopletoolssrcpsappengaedebug.hSQL error. Stmt #: 1603  Error Position: 0  Return: 805 - [Microsoft][SQL Server Native Client 10.0][SQL Server]Cannot insert duplicate key row in object 'dbo.PS_COMMUNICATION' with unique index 'PS_COMMUNICATION'.

The keys on the Communication Table are the COMMON_ID and the SEQ_3C.  So, most likely, the problem is that is trying to insert a Sequence number that already exists.

Here is some SQL that you can use to find the problem:

SELECT TOP 200 A.COMMON_ID, A.SEQ_3C, B.SEQ_COMM_LAST
FROM PS_COMMUNICATION A, PS_LAST_3CS_TBL B
WHERE A.SEQ_3C = (SELECT MAX(SEQ_3C)
FROM PS_COMMUNICATION
WHERE COMMON_ID = A.COMMON_ID)
AND A.COMMON_ID = B.COMMON_ID
AND B.SEQ_COMM_LAST < A.SEQ_3C

Here is some SQL that you can use to fix the problm:

UPDATE PS_LAST_3CS_TBL
SET SEQ_COMM_LAST = (SELECT MAX(SEQ_3C)
FROM PS_COMMUNICATION A
WHERE A.COMMON_ID =  PS_LAST_3CS_TBL.COMMON_ID)
WHERE EXISTS (SELECT ‘X’
FROM PS_COMMUNICATION A
WHERE A.COMMON_ID =  PS_LAST_3CS_TBL.COMMON_ID
AND A.SEQ_3C > PS_LAST_3CS_TBL.SEQ_COMM_LAST
AND A.SEQ_3C =  (SELECT MAX(SEQ_3C)
FROM PS_COMMUNICATION A
WHERE A.COMMON_ID =  PS_LAST_3CS_TBL.COMMON_ID) );

If you want to look at the code in the App Engine, the Sequence Number is calculated in the 3CENGINE_LIB.COMMLSEQ section.  It loads the Sequence number from the PS_LAST_3CS_TBL table.
