Update Data with Rest API in Application Studio

[jhonatanchayadi]

Dear Community,

I’m currently trying to learn how to use Rest API in Application Studio to update data.

I created a button to update the second “Description” field and then call the rest api to update it

but the data is never updated, i checked on the payload the rowmod still blank “”

Is there something that i miss?

Thanks

Are you sending in a RowMod - U

[jhonatanchayadi]

how do i set row mod “U” in this application studio?

Ok. so i succeed on sending the RowMod “U” but now here’s the new error

Object reference not set to an instance of an object.

The data is from PurTerms.GetRows then i just use row-update to change Description and RowMod to “U” then pust it to rest-erp PurTerms.Update

You don’t need RowMod.

Add this:

You don’t even need to specify the method parameters.

And, before you ask how it knows what DataView to use, it’s based on the Dataset ID.
These will do the same thing:

note from my event, i need to remove my “data-commit” first to make it works
