converting Import File to API Required Attributes.

Hi,

In our old code, the application creates a file with headers and data separated by Tab and saves it in local machine, then an employee would upload the File to MYOB account.

For an improvement, we decided to directly upload/push the invoice in the MYOB using the API. Upon reviewing and comparing, the File Header of theupload file and the required fields on the API, They are very different, can you point me or which file header corresponds to the Item Invoice API required fields?

attached is  the sample upload file that old app have created
