In a Map Reduce script, why am I getting the error

Cannot find function setCurrentSublistValue in object standard record.","stack":["createError(N/error)"],"cause":{"message":"Cannot find function setCurrentSublistValue in object standard record.

The relevant code is below. I am trying to simply copy the lines from an Invoice -> New Opportunity record.

log.debug({
                title: 'Begin Create Opportunity',
                details: '.'

            params.inactiveItem = '';

                title: 'params',
                details: JSON.stringify(params)
            });
            log.debug({

setCurrentSublistValue

is only available when the record is in dynamic mode. You will need to add

isDynamic: true

to the record.create.

will try that, didnt think you needed it when creating a record. Thanks!

don't use dynamic mode apis

k

I would revise that to say don't use them unless you have a specific reason to use them.
