Hello everyone, 

I'm trying to load Sales Orders through the template "SourceSalesOrderImportTemplate.xlsm", however, when I try to load it to the ERP through Schedule Process "Load Interface File for Import" it has a slow performance issue. 

I explain the process of how I doing it and maybe someone has a solution to this slow performance issue.

1. We fill the template "SourceSalesOrderImportTemplate.xlsm" with all the values required to create the sales order and then we generate the CSV File.
