StartFunctionalGroupHeader Method

Creates a new EDI functional group header segment on the current document.

Syntax

edifactwriter.startFunctionalGroupHeader([callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

When called, a new functional group start (GS or UNG) segment is created and set as the current segment. You should then set the values on said segment before adding a new transaction set within the document.
