Get the summation of a column group by another in a View

I have created the following view based on the joins you can see in the screenshots.

And the result is shown here:

What I want is to sum the Qty based on StatusReceipt. So instead of 4 lines of Registered I want a single line with the Qty of 4

    What's the problem?

    The problem is I don't know how to do it ;)

    I know how to group the StatusReceipt column but I don't know how to sum the Qty?

    Let me focus on InventTrans table only, so we don't get overwhelmed with all the other stuff in your view. If you do many things at once, you'll often achieve very little.

    Start with thinking about what SQL code you want your query definition to generate (a view is based on a query). If you want to sum values in a field, you use the aggregation function called SUM. And grouping is done with the GROUP BY clause. Therefore the SQL code would look like this:

    select sum(Qty) from InventTrans
        group by StatusReceipt

    To add such as summed field, add Qty to the field list and then change its Aggregation property from None to Sum. You know how to add grouping, so I'm not going to describe it.

    If you don't get right results, you can review the actual query in database (after DB synchronization) and review how it differs from the query that you intended to generate.

    If you're not familiar with grouping, you must realize that the only fields that have values are those used for grouping or are aggregated. Values of other fields aren't defined and therefore you'll see them as empty.

    The Aggregation from None to Sum helped me in so many other reports i created, Thanks Martin!
