Gallery lookup data linked to other gallery not working using CDS

(0) ShareShare

Posted on by ThomasVDS 102

Hi,

 

I have 3 tables which I linked using relationships:

- Consultants

- Training history

- Training list

From the training history entity I have 2 relationships 'many-to-one' to the other 2 tables.

I first select a consultant, then I want to see which trainings he has followed.

The second gallery is shown the trainings correctly via Items: Gallery2.Selected.'Training Histories'

But I can't show the lookup columns like 'ThisItem.'Training ID' -> expected text value (see attachment).

I also tried to show the training name which is present in the training list entity via 

LookUp('Training List','Training ID'=ThisItem.'Training ID','Training Name')

This gives the error 'invalid argument type'.

 

Any help would be great! Thanks

    @yashag2255Thank you, it worked!

     

    For the training ID -> ThisItem.'Training ID'.'Training ID'

    For the Training Name I even didn't need to do a lookup -> ThisItem.'Training ID'.'Training Name'

    Hi @ThomasVDS 

     

    Can you please confirm the name of attribute you have used for creating the lookup? Lets suppose its name is "LookUpField", the label text expression will get modified to:
     
     ThisItem.LookUpField.'Training ID'
    or to display Training Name
     
    LookUp('Training List','Training ID'=ThisItem.LookUpField.'Training ID','Training Name')
     
    Hope this Helps!
