RE: Copying matrix item and setting the value of a multiselect field

I’m using record.copy to copy an existing matrix item to create a new record and update a couple of fields with values for the newly copied record. The matrix item has a custom field that’s multiselect type representing length.

I can’t figure out how to set the value of the new record to get it to save properly. I keep getting an error of this type:

Invalid item option custitem_size for item xxxx

My code is:

var newRecord = record.copy({
            type: ‘inventoryitem’,
            id: 17386,
            isDynamic: false
newRecord.setValue(‘custitem_size’, ??????);
var recordId =;
I tried several values for ?????? but I still get errors.

Thanks battk. I’m trying to use record.copy since most of the data from the source record (which is already a child record) is the same on the new matrix record with the exception of length or size which is represented by the custom field.

Since I could not get it to work, I finally used record.create ad populated the fields I needed and the only time it worked to save the record is when I included a value in externalid because previous attempts were unsuccessful (hence the need to try record.copy) as I was getting a DUP_ITEM error message every single time I tried creating and then saving the record.

You probably still need to set the non standard matrix option fields to new values.
