RE: Attempt to write duplicate record...

Correct. And the joblog will tell you which logical's rules were violated, and (IIRC) give you the RRN of the matching record. (And I thought I'd never say "matching record" in this century. Here I've said it twice.)

Hi Roger
Does the file have any logicals with unique keys
That can also create the problem that you are facing
Even though THIS file may not have a record already out there, data in
this write attempt may be a duplicate of that logical

Subject: Attempt to write duplicate record...

Hi All,

I had a stored procedure fail with RNX1021 Attempt to write a duplicate
record to file SIGNTMP.

SIGNTMP has the following constraint:

Constraint
Description
Primary Key
Constraint
Constraint . . . . . . . . . . . . . . : CST
Q_QS36F_SIGNTMP_WK
Type . . . . . . . . . . . . . . . . : TYPE
*PRIMARY
Key . . . . . . . . . . . . . . . . . : KEY
WKCUS#

WKITM#

WKDOCT

WKDOC#
Number of fields in key . . . . . . . :
4
In the code I have...
// Write to the work file if not already there
Chain(n) (p_store: p_item: p_DocumentType: p_Document) signtmp;
If not %Found(signtmp);
wkcus# = p_store;
wkitm# = p_item;
wkdoct = p_DocumentType;
wkdoc# = p_Document;
Write signtm;
Endif;

I thought this was pretty solid code but the program still failed. A
new
record is only written if a record with the same key is not found.

So my only explanation is that another process wrote a record with the
same key in between the Chain and the Write.

Am I missing something of does some have another explanation.

BTW, I understand that I can add an error extender to the Write and
capture the error but my question still remains if there's another
explanation for the failure...

Thanks for all ideas,

Robert Rogerson
