I have 100 items of data, which are grouped together in various sub groups using a field 'groupNo',

I want to process each set of groupNos individually, I need to select a group, and do the following processes for each individual group: Take one item with status 'original' which has data and duplicate that data to the 'new' items in that group. How would I do this using the groupNo identifier? 

An example input output data set:
 

Input:
OID, Status, Data, Group
1, Original, XYZ, 1

2, New, <null>, 1

3, Original, ABC, 2

4, New, <null>, 2

5, New, <null>, 2

 

Output:

OID, Status, Data, Group
1, Original, XYZ, 1

2, New, XYZ, 1

3, Original, ABC, 2

4, New, ABC, 2

5, New, ABC, 2

 

 

There are many ways to process it. You can use FeatureMerge to merge attributes. Firstly, you have to filter Null value and has a value of "Data" field, then you can use set of Null data as Requestor with key "Group", and set of has a value data for Suplier with key "Group". You will have a result with features with attributes are merged, then use another transformers to get attributes you need such as AttributeRenamer, CreatorAttribute, AttributeValueMapper.....
