when it comes to mapping Employee - Code, because it is numbered list. This is something you need to map on the 'Mapping' tab. Please select Code to map the Employees correctly, make sure that on tab '#E2 Employees' all of them are mapped. So, you dimension in your SYS08 module are Employees, and you are loading attributes of your employees, like Code, Start Date, Salary etc.
Now, looking at the Line Items.
Active? -> what is your source? is it saved view of a module? probably Data Hub? I assume Active? is only used as filter, to filter out employees who are not active. You do not need this information really. Else, if you need it, then would create boolean-formatted Line item in your SYS08 to map it. Does it make sense?
Employees -> I believe it is name of an employee, probably it needs to be mapped to the 'Name'
Thank you for such a detailed explanation. All points understood. Regarding Active? =you are correct, it is used as a filter to filter out among all the employees who are active, throwing result TRUE & FALSE in source file but in my target file in course, it did not mentioned anywhere that active? is one of the line item we need to add. If i want to add it then how to go about it?
