i have about 500 transfer orders that we need to close, we are using a map/reduce script setting the status didnt seem to work what is the next best option

record.submitFields({
      type: record.Type.TRANSFER_ORDER,
      id: data.id,
      values: {
        // postingperiod: "157",
        status: "Closed",
      },
      options: {
        enableSourcing: false,
        ignoreMandatoryFields: true,
      },
    });

you may need to load each record, loop through the lines and check the

closed

box for each

the closed line or main ?

Yep. You'll want to set

isclosed

to

true

for each line item on the transaction. When they're all closed, the transaction itself should change status to closed.

I think you can do this by voiding a transaction, N/transaction module, this module supports transfer order.
