Hi Readers,
I am sure everyone was able to publish your extension based on the Last article. If you haven't read the earlier article, then
refer to the table of content.
As promised in the article we will add code to check Source of sales is filled in during the posting of sales order as per customer requirements.
The user should be able to select the Source of sales in Sales documents and its a mandatory field to key in before posting a sales document.
Let's try to add this Code to our extension.
