associate rows with previous rows

Have a look at the settings for the AttributeCreator transformer.

At the top you will find an option to get attributes fro the previous or next feature.

That should help you creating the attribute you need.

Hi Erik_Jan

thanks for the speedy response. I have been trying to make the Previous \\ Next feautures to work in my scenario, but can't work out a way to make that dynamic.

As there can be anything from 1 to 7 staff in a GP Practice, so sometimes i need 1 prior feature, sometimes 2, ... and sometimes 7.

Because the features are processed in order, you should only need to access the previous feature, once you have set the value for row2 you can use that in row 3 etc.

Gives this output

You can use the method outlined by @erik_jan, along with the conditional values in the Attribute Value parameter.

Set the number of prior features to the max number of staff below the practices. You can choose as high of a number as you wish.

In the Attribute Value column, use the conditional value option to build the following test...one for each of the number you specify. The next would be feature[-2].type, with the Attribute Value set to feature[-2].name, etc...

You will want these in sequential order in the conditional values. The [-1] test should be on first.

thanks everyone, its doing exactly what i needed.
