how to add ? more side columns
journal entries are rarely needed in Manager, even less the custom fields for it.
what transaction are you making as a journal entry that needs a custom field?
yes,I need Savings Tab Columns And Total Savings Can you Help Sir? 
you cannot create line item custom fields for journal entries. but you can create custom fields for the whole form. read the guides section regarding this.
i still do not understand your need of these columns. other users can guide you if you can explain more clearly what you are trying to do.
This does not make sense. There are no savings involved with journal entries. Each journal entry must balance debit(s) against credit(s). The numbers are what they are. Why are trying to show savings?
