OK, I've got an update if anyone's interested,

To try and analyse what records are being dropped, I put in two store qvd instructions in the load script (one after StockLC is concatenated into Relationships and one after CustXRef).

Interestingly the number of records in the first store is not the same as the lines fetched in the script above (it's lower) and the second qvd after CustXref does increase the rows added to the table by around 150,000.

So is this a bug in the script execution dailaog box or am I misinterpreting what it's saying?

My thanks again for any advice.

Thanks

Derek
