In Macola ES, you cannot change the numeric / alphanumeric structure once you choose the method for the chart of accounts, customer and vendors. Though the physical field is a character field, the system changes the justification of the data based on whether the setup is numeric or alphanumeric. If the company is set up as numeric customers and you enter number 2345 it stores it as ' 2345' since it's a 20 character field and it pads it with leading spaces. If the company was set up as alphanumeric customers and you entered the same thing, it would be stored as '2345' because it would left justify everything.
