If I run the report by itself using crystal, it works without a problem. However if I try to automate it, it gives me an error. I read stuff online but none of which was helpful.Thanks.

What's the datasource? How it's build up. Subreports? Grouping, etc...If it's a dataset does it have multiple tables? Is there a relationship defined in the dataset? Does the relationship match the database links in your report design (same parent table, same child table) | Post Points: 5 homerj07 Since 2/24/2004 Posts 786 Reputation 9,285 Reply Homer Simpson (homerj07) replied on 2/18/2005 1:43 PM rated by 0 users Dries,After thorough investigation, I have managed to resolve my issue. Within my store-procedure I had two columns from two different tables with the same column name and I guess during the automation, Crystal got confused and gave that error. I fixed my stored-procedure and it is working flawlessly.Thanks for your help. I apologize for not getting back to you soon.
