CDS error writing data to entity

Hi there

A year ago I created some apps with the default canvas method. One of these apps is named "SimpleLeerkrachten". It holds names and codes for teachers at our school. U can see this in my screenshot named "App Leerkracht.JPG". De app is connected to an (upgraded) CDS entity called "Leerkracht". U can see the fields in my screenshot named "entity Leerkracht.JPG". The app worked perfectly but now we are testing it again to add new teachers to the list. Whenever I click on the + button in the app, I can see and fill in the empty fields (p.e. field "LkrCode") Now when I click on the submit button (= a check mark in my app) I get an error saying  "There is a problem with saving the data. Probably the datasource is invalid." The data is not saved in the entity. The app uses a "Submitform(EditForm1)" when I click the submit. How can I solve this issue? In the past it worked perfectly.

Thx a lot in advance for any suggestion that could lead me to a quick and defintive solution. 

Greetz, Walter

Re: CDS error writing data to entity

Hi @Walter , 

 

As requested in your other request, can you please share the following details?

 

Are you able to get the data from the entity? 

 

Can you please try deleting the old CDS connection and create a new one and try again?

 

 

Thanks,
