Passing a View to a Function

hmwillett · July 27, 2021, 6:20pm

Is there a way to pass a DataView to a function from App Studio?
If have a runtime view called MemoView that displays a list of stuff (rows/columns).
On a button click, I would like to send that whole view in its current state to my function as a DataSet in order to do more processing.

I created an IN parameter that was of type DataSet, but it gave me this when I passed it in from App Studio:

So I thought maybe it was sending JSON as a string? I changed my parameter to a string and tried to deserialize the object and got this:

I don’t think that is possible right now using erp-function event action.
Suggest you use the rest-erp event action instead, and setup the dataview details on the Request Arguments.

AppStudio Help has an example of calling a EFx using the REST-ERP action.

hmwillett · July 27, 2021, 6:44pm

I’ll take a look at that.
Thanks!

It seems the documentation has been updated to use the ERP-FUNCTION widget now. Any chance you can share a copy of the original or another example?

@Callum_Stott I just tried passing a dataset to an EFx using the REST-ERP.

Seems like it has a bug, the dataset did not actually get passed. I have asked someone to file a case for it.

The steps would be:

Ensure that the EFx library is promoted to Production
Launch AppStudio → Event Designer.
Setup a new event with the desired trigger.
Drag the REST-ERP widget
Set it up with below:
a. Call Options
i. Library Name
ii. API Key (this is optional from 2021.2 onwards)
b. Service Operation should be the Function Name
c. Setup the Method Parameters manually (if any)
d. ERP Rest Arguments → Request Parameters – setup the View Name and Parameter Name (i.e. table name that the EFx expects)

I thought Timothy Schilling had an example of this, have you reached out to him? I feel like we did something similar at insights, but not exactly this.

He said he would always respond because he always checks his email.

If you don’t have his email let me know!

hmwillett · September 15, 2021, 6:40pm

I didn’t, no. I actually went a completely different direction.

Sorry, I should have come back to post an update. I did get it working in the end. Below is a JSONC code extract of the configuration I ended up using. It is working for me in 11.1.100.10 and was in 11.1.100.04 also. Thanks for your response and detailed steps!
