   I am using a dataset model class to create/update records in a table. I am getting a bunch of conflicting record errors. I have no idea as to why. Do you see an issue with the usage of that class in the internal procedure below?

     END FINALLY.
     
    END.
   END PROCEDURE.

   Do you get the conflicting records in case of 
   
   IF NOT oRebateCustomer:RebateCustomer:Available THEN
   
   or when the record is available?
   
   Any suspicious code in the Business Entity or Data Access class? What's your AssignSkipList?

   This is occurring when the record is already on the DB. I can add some logging to see if the DatasetModel class thinks it is available.
   
   The BE is what was created from the designer. No addl code added to ValidateData or ReceiveData.
   
   As far as the DA we do have the validation hook methods defined but they are not being used. I can remove all that and try again.
   
   We are not using assignskiplist

   Every time it happens the dataset model class cannot fetch so we then try to create. Since the record is already in the DB we get this error.

   When the DatasetModel does not return the record although it's there, please double-check that the constructor of the DatasetModel uses the right fields to filter.
   
   Please enable detailled Data Access logging, to verify the database queries as well.
   
   Please also check if the Business Entity is implementing the IFetchDataByReference interface and the FetchDataByReference method is implemented according to the template for Business Entities.

   Will do. We cannot duplicate in our office but it is occurring at all 37 sites we just implemented this in. It must be something specific to their DB. We have requested a backup of their DB to load up in our office.
   
   thanks,

   Hey Mike,
   
   We finally received a backup of the customers DB and the issue is their DB. The RebateCustomer table has a JOIN to another table and for some reason the customer's DB is missing the JOINED record resulting in the RebateCustomer record to not be available.
   
   Our reseller support rep fixed the DB issue 30 minutes ago and now the record is available as it should be. 
   
   We are updating the DataAccess class to use an OUTER-JOIN as well.
   
   Thanks for the support.
   
   Stay safe!!
