Hi,

I'm facing some troubles to figure out how to transfer some attributes that are present on some text lines to subsequent text line features.

See below a screenshot of my data situation

Whenever -99 occurs a new dataset begins. The next two number are static values and then various measured records will occur. What I'm trying to achieve is, to pass on the two static values to every record ot the dataset. As soon as a new dataset (-99) begins the mechanism should reset and now use use the most recent values for inheriting.

Find attached my current workspace together with a small sample dataset.

 

Thanks for your help!

Hi @whkarto, if I understood the requirement correctly, this workflow would be a solution.

    Take a look at the adjacent attribute handling capablilities under advanced attribute value handling in the attribute creator. This will allow you to set a value of an attribute based on a value in the previous feature

    As an aside, if your data is as per your sample, it's a lot easier if you read the text file as column aligned text

    Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

    @takashi Thanks a lot! Once again you did it! The approach with variables ist really clever, although you'll have to make sure that data schema is strictly obeyed. But that could be done in advance.
