I created lines in purchase and sales invoices through custom fields option, I have never used them and have no intention. what is the process of deleting these lines as these are not required but due to repeated tries I could not delete them. can you help me in this regard… Thanks
Typically, when something cannot be deleted in Manager, that is because you have used it or it has been referenced by a transaction. All such references must be deleted first.
But what did you mean by “I created lines…?” Did you mean line items? Those are not created by custom fields, and are deleted by clicking the X to the right of the line:
If you are actually referring to columns (vertical) as opposed to lines (horizontal), that is a different story. Columns do not appear on completed forms unless there is something in them in at least one line item. (Description, Unit price, and Amount are exceptions. So again, you need to get rid of the unwanted entries before they will disappear.
