Hi folks

I have built a tree lookup: another thread of mine. Now I want to save the user selection. I am more than capable of doing this by creating a custom table to do the job. But I have a vague suspicion that I should use SysLastValue. I am aware of the user-last-value functionality. But I am not exactly sure how it works. And I have not used it before. Hence I do not know why it isn't working for this form of mine in the first place.

The tree is built from some tables, but there are no datasources on the form. I know that the last value functionality works if I use a contract / SysOperation. But I do not feel like that is relevant for this implementation of mine.

Should I 1) build my own table 2) use the SysLastValue table or 3) change my tree lookup in some way that the standard user-last-value functionality works?

Thanks for your attention.

You can use SysLastValue, but you won't get it out-of-the-box. The system simply doesn't know what it should save for your tree control.

I'm not completely sure what's the right solution for saving and loading such values in D365FO, especially now when we're moving from a single set of last values to saved views. Maybe element.configurationHelper().saveConfigurationValue() and getConfigurationValue() is the right way...

Thanks Martin

I use the user's tree node selections on numerous forms, so in the end I decided that the best solution would be to just save the values in a custom table. Which enabled me to actually join on the user's selected bank accounts.

I am sure I will come across a similar requirement in future, in which case I will try the configurationHelper() approach.
