Patent ID: 8229908

Claim:
A computer-implemented method for facilitating simultaneous modifications to financial-data, the method comprising: receiving a first file comprising financial data at a computing system comprising a processor; receiving division-criteria at the computing system, wherein the division-criteria facilitates dividing financial-data into a first subset and a second subset, and wherein the financial-data comprises transaction data with one or more fields and corresponding values; creating a second file comprising a copy of the financial-data which includes the division-criteria, wherein both the first file and the second file comprise the first subset and the second subset; allowing a first user to modify the first subset in the first file; creating a first lock to prevent the first user from modifying the second subset in the first file; creating a second lock to prevent a second user from modifying the first subset in the second file; sending the second file to the second user, thereby enabling the second user to modify the second subset in the second file to create a change file; receiving the change file from the second user, wherein the change file comprises modifications to the second subset; merging the change file into the financial-data in the first file; and releasing the first lock.
