Multiple P.O.'s on a single invoice

[onepathvann]

How have just been awarded a contract. The contract consists of 37 seperate purchase order numbers and req numbers. The county wishes to be billed on one invoice. I have changed my headings on my invoice. But, when I enter the P.O. data into the column the number is treated as a entry of a mathematical formula. HELP! How can I disable the feature for that column or any column.
Thanks,
Bob

The columns on the default invoice templates that are named Rate and Qty are formula fields and will total to the Amount column. DO NOT rename them and expect that they will not caculate.

You can use the "other" columns for your PO numbers.
