Hi All,

I have data in two tables that I would like to incorporate into one table.

The first table is a customer order table at individual order level (customers can have multiple orders)with Customer ID and Quantity ordered columns ( as well as a lot of other columns). The second table is a Customer despatches table at individual order despatch level. This has customer ID and and quantity despatched columns ( plus other columns).

I now need to create a new table at customer ID level which will have the columns Customer ID , Quantity Ordered, Quantity Despatched.

How can I go about achieving this.

All help appreciated

Herbert

Is there no column in any of the two table like order number which marks a particular order uniquely?

Usually it's enough to create a straight table with Customer ID as dimension and two expressions: sum([Quantity ordered]) and sum([Quantity Dispatched]). If you want to calculate it in the script you can do something like this:

SummaryTable:

Load [Customer ID], sum([Quantity ordered]) as [Quantity Ordered Customer Total]

Resident Orders

group by [Customer ID];

join (SummaryTable)

Load [Customer ID], sum([Quantity Dispatched]) as [Quantity Dispatched Customer Total]

Resident Dispatches

group by [Customer ID];

Thanks Gysbert,

I am getting a syntax, which says "missing/misplaced FROM: SummaryTable:..." I have converted your code to:

SummaryTable:

LOAD TIMB,

Sum([Bales Loaded]),as [Total Loaded]

Resident [Bale Loop]

group by TIMB;

Thanks Herbert

You have a comma just before the as that shouldn't be there: Sum([Bales Loaded]),as [Total Loaded]

Fantastic Gysbert,

The join worked perfectly. I have added a bit more to the code to say Total Loaded - Total Delivered.

For some strange reason, the calculation is working fine where there is a value in both columns Total Loaded and Total Delivered. Where there is a value in only one of the columns, it is not performing the calculation. The code now looks like this:

SummaryTable1:

LOAD TIMB,

Sum([Bales Loaded])as [Total Loaded]

Resident [BALE LOOP]

group by TIMB;

Join(SummaryTable1)

LOAD TIMB,

Sum([Bales Delivered]) as [Total Deliveries]

Resident BOOKINGS

Group by TIMB;

[SUMMARYTABLE]:

NoConcatenate LOAD

    TIMB,

    if([Total Loaded]='',0,[Total Loaded]) as [Total Loaded],

    if([Total Deliveries]='',0,[Total Deliveries]) as [Total Deliveries],

    [Total Loaded]-[Total Deliveries]

    

    Resident [SummaryTable1]

    Order by TIMB;

    

    DROP Table [SummaryTable1];

Please help.

Thanks

I think in this case what you can use is the rangesum function, which can deal with nulls.

[SUMMARYTABLE]:

NoConcatenate LOAD

    TIMB,

    [Total Loaded],

    [Total Deliveries],

    rangesum([Total Loaded],-[Total Deliveries]) as Result   

    Resident [SummaryTable1]

    Order by TIMB;

If you want to test for null values (or blanks) use if(len(trim(SomeField))=0, ...
