Combining values from common examples into new attributes

Hi All

I have the following list:

 

Drug ID     Drug Name     Ingredient

23              Centrum         Vitamin D

23              Centrum         Vitamin B

23             Centrum          Vitamin C

 

I need to convert this into:

Drug ID     Drug Name     Ingredient1           Ingredient 2            Ingredient 3

23              Centrum         Vitamin D               Vitamin B              Vitamin C

 

I have tried everything and playedaround and could not get an answer... 

 

Help ??

Hey,

 

you can go for Aggregate group_by Drug Name and concat(Ingridient), this gives you

 

Drug ID     Drug Name     Ingredient

23              Centrum         Vitamin D|Vitamin B|VitaminC

 

 

Afterwards you can use a Split operator to split the Ingredient on \| to get the desired output. Attached is the demo process.

 

Best,

Martin
