Re: Missing records after associations for table above 10000 rows
First: Never Use Table Box to compare the result of the LOAD information because when you add the dimentions in a Table Box IF you have repeated rows the table box interpret like a DISTINCT and only will put one row for repited records. For This You have to use a STRAIGHT TABLES.
Now in response to your question is because QlikView interpret the load like a JOIN and how does work a Join?
This means that if multiple columns are shared between tables, the match will be made over the distinct
