On the Sales Order Entry screen we enter a specific customer then hit save. Under the Header tab, then the Comments tab, comments are automatically loaded in. What is driving this? I am sure it is a BPM, but what would it even fall under?
You can check pretty easily. In Method Directives Maintenance, click Method Code to open the search dialog and select 'Search by Directives" and then click search.
If you see a SalesOrder business object, then you have some sort of BPM affecting order entry.
We have this. It seems like this is handling that portion. The problem I am having though is when a user wants to add more lines below the comments that populate, it will not let them. They can type more, just not add a new line in the comments.
Erp.Tables.Customer Customer;
foreach (var ttOrderHed_iterator in (from ttOrderHed_Row in ttOrderHed
where string.Equals(ttOrderHed_Row.RowMod, IceRow.ROWSTATE_ADDED, StringComparison.OrdinalIgnoreCase)
select ttOrderHed_Row))
{
var ttOrderHedRow = ttOrderHed_iterator;
Customer = (from Customer_Row in Db.Customer
where Customer_Row.Company == ttOrderHedRow.Company && Customer_Row.CustNum == ttOrderHedRow.CustNum
select Customer_Row).FirstOrDefault();
if (Customer != null)
{
ttOrderHedRow.OrderComment = Customer.Comment;
}
}```Well I feel stupid. Global Options, Hot Keys, handle enter as tab was checked. ugh…
Does shift-enter allow additional lines? Sometimes enter as tab will allow shift enter to add new lines. 
Shift-Enter doesn’t work for me when Enter is handled as Tab.
Ctrl-Enter works my bad shift is wrong one.
