I can not really follow ...

A saveInto will only evaluate after the user modifies the value of the field.

such as this

 a!textField(
                          label: "Username",
                          labelPosition: "ABOVE",
                          value:fv!item.KONE_user_name,
                          saveInto: {
                            a!save(target:ri!userinputsheet.KONE_user_name,value:fv!item.KONE_user_name),
                          a!save(target:ri!userrole.NAME,value:save!value),
                          a!save(target:ri!userrole.USER_ID,value:a!localVariables(local!value:fv!item.KONE_user_name,
                          a!forEach(items:rule!KONE_Development_Username_UserId(),expression:if(local!value=fv!item.username,fv!item.userid,{}))
                          ))
                          },
                          refreshAfter: "UNFOCUS",
                          readOnly: true,
                          validations: {}
                        ),

i set the value:fv!item.value saveInto:ri!table.value. I mean if I don't do anything in that text blank(type or click), then the fv!item.value will not be saveinto ri!value, just leave it null.

This is super confusing.

As Ravi said, Appian will insert or update depending on the value of the primary key. If there is not value (null) then it becomes an insert, else an update.

Now you need to find out what you do to all the data in your interface and whether the PK is null or not.

saveInto:ri!table.value but it is not work

can you give an example

If you want to update a row it means the data is already present in your database, hence first you need to query the record which you need to update so you get the primary key id for that record, update the record and let the primary key id assigned/unchanged what you get upon query the record. This will update the record instead of inserting a new row.

Seems how can I let it recognize the username because i didn't fill into it, how can I let it auto fill in? Thank you

ids for this class must be manually assigned before calling save(). report as this error
