Due to the different structure of the software previously and the current upgraded GST version, After upgraded to the GST version, you cannot view the sales analysis report for the previous periods.
You are advise to view the current period of sales analysis in the upgraded database and you may need to maintain the old database for u to view the sales analysis for the previous periods. otherwise,
You are require to scan the database for only the sales module and select the periods after your last audit periods. if u wish to do that, Please backup the database before u scan and let us know the status after your scan. thanks.
