How to instaure a default value to continue the translation

Instead of the Tester you can use an AttributeManager with a conditional value for that attribute. That essentially incorporates a Tester in the AttributeManager.

Maybe the NullAttributeMapper can be of help here. This transformer can replace Null values or empty strings with another value, like 0.

Thanks for the answer. The difficult part of it is that there’s multiple attribute to deal with, the unique attribute which group all of them comes later (where i could make the conditionnal value) into the translation and is already empty. I struggle finding the good logic telling him “if i’ve no values between with theses 4 attributtes write the default value “0”

Hi thanks for the answer. yes thaught about it but since the translation doesn’t even aknowlege the empty rows (it just skips it) i can’t mapper on this particular row/attribute. do you know how to force a non skip and add an empty row ? 

I'm unclear what you mean by empty rows here.

Can you provide some sample data?

Hi, sorry for the late. Ok i’ll train explain the best i can with screenshot : 

I’ve 4 categories : 

• water system components
• connection terminal 
• manholes
• water treatment plant

as you can see, the output only give me 2 values because some values are empty/null. I want to be able to say “If the values are empy/null, the default value is 0” but i’ve to say this for each categories. I know it has to be an attribute manager instead of a tester but i struggle to translate in FME

At the start of each category add a NullAttributeMapper that changes Null values or empty strings to 0.
