I bookmarked a group of transformers that will create a random attribute value of fixed length and a text format of T######## (where T is a random capital letter and # is a random number between 0-9). I used an unconditional featureMerger to merge the value to my features . I need to be able to loop each feature into the bookmark so I can generate random value for each feature in the transformer.

With my current workspace I can only pass one value to each feature. Workspace below.

Do you know the RandomNumberGenerator transformer that exists in the Transformer Gallery?

That should help in this case without the need of looping.

No need to loop you could do in line

Hi @geospatiallover, I would create a random capital character with a RandomNumberGenerator and a CharacterCoderRepacer, create random eight digits with another RondomNumberGenerator and a StringFormatter, and finally concatenate them with a StringConcatenator.

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