To upload transaction data into a BPC system using a flat file approach, the following steps should be followed:
1) Create dimensions, models, and connections in BPC.
2) Use the data manager to upload a CSV file, select a transformation file, and validate the data.
3) Create a data manager package to extract the data from the front end system to the back end BPC system.
4) Run the package to upload the validated transaction data into the appropriate dimensions in the BPC model.
