Create a dimension from existing dimension

[#1]

Hello,

I have a doubt and i would need your help if possible...

I have one expression which is based on one existing dimension, but what i need is to create an expression based on that same existing dimension.

I am attaching the example. I have the expression that gives the result "COLOAD" or "SINGLE" andit is based on the existing dimension "Shipment ID". But what i need is this result ("COLOAD" or "SINGLE") to exist as a dimension based on the Shipment ID.

Is this possible ??

The thing is that i need to somehow have a way to exclude or not the co-loads from the Filling Rate % table, and i am not seeing any other way of doing it. What says if a shipment is coload or single is if the same Shipment ID has two  different warehouses or two different deliveries. That's why the expression is :

IF(COUNT(Warehouse)=2,'COLOAD','SINGLE')

I would really appreciate if someone could help me on this.... (file in attach)

Thanks

Try using something like this in your load script, it should then link back to your shipmentID and allow you to use the 'Coload' field as a dimension.

Coload:
LOAD OQETRN as [External tracking number] ,
if(count(OQWHLO)>1,'Coload', 'Single') as 'Coload'
Resident MHDISL;

Hello Leonard,

Thanks a lot for your help, i was not aware of the "Resident" function...

However i have have placed the code on the script but i got the following error:

Field not found - <OQWHLO>

LOAD OQETRN as [External tracking number]

if(count(OQWHLO)>1,'Coload','Single') as [Coload]

Resident MHDISL

I am not finding the reason for this mistake as the field OQWHLO is already defined...

Could you help me on this ?

Thanks a lot
