Periodic Processing: Data Transfer 
The FI-SL System provides you with the following programs for transferring non-FI-SL data into the FI-SL System:
With this program, you can load data from an external source (non-SAP R/3 System) to the FI-SL System. RGUREC00 is only an example program and should be copied and modified according to your needs when you process postings.

If you changed the standard coding block delivered with your FI-SL System, you will need to change the RGUREC00 program so that it reflects new dimensions that you have defined.
For information about loading data from external sources with RGUREC00, you should contact an SAP consultant.
