Hi! I need help. I'm trying to setup a cascading dropdown against CDS.

I have a list called Maskin and one called kund. All list i have are lookups through a list called tillverkning.

Items:

Distinct(Maskiner;Maskin)

Distinct(Filter(Tillverkning.Maskin.Maskin = ComboBox1.Selected.Result);Kunder.Kund)

What am i doing wrong? 🙂

Hi @JohanF ,

Could you please try with this?

Distinct(Filter(AddColumns(Tillverkning;"NewKund"; Kund.Kund;"NewMaskin";Maskin.Maskin);NewMaskin = ComboBox1.Selected.Result);NewKund)

Hope this helps.

Thank you for the replay.
I now can select the right value! thats great 🙂

But when selected the value in combobox1 (maskin) and the combobox2 (kund) and press the submitform button the data is only saved in maskin list.
i want it to save in the tillverkning list.
is that possible?

Hi @JohanF ,

What is the data source of Form?

What do you want to save to tillverkning list?

Could you please share some example?

If you means save the two combobox selections to a new record of tillverkning list, please try to apply this to OnSuccess property of Form.

Patch(Tillverkning, Defaults(Tillverkning),{Name:"Test", Kund: LookUp(Kund,Kund=ComboBox2.Selected.Result), Maskin: LookUp(Maskin, Maskin=ComboBox1.Selected.Result )})

Hope this helps.

Hi @JohanF ,

Please try this, the operator should fit your localization.

Patch(Tillverkning; Defaults(Tillverkning);{Name:"Test"; Kund: LookUp(Kund;Kund=ComboBox2.Selected.Result); Maskin: LookUp(Maskin; Maskin=ComboBox1.Selected.Result)})

Hope this helps.

Hi again!
i tried that but it diden't work. 🙂

i changed back to the first setup we used were i can select the Maskin and then get the right value in kund.(but it doesn't save too tillverkning)
i tried adding a form and pointed that to tillverkning and after that change the items for Maskin and kund. (See pics)
But i get a error.

the value needs to be an entity post
