Important Profile Parameters
Important Profile Parameters
Definition
The recommended SAP profile parameter settings are listed below for the various application modules being used on any SAP instance. For large SAP client/server installations containing many application instances, the settings for one application instance may vary significantly compared to another. This is expected as the various application work groups will most likely be segregated from one application instance/server to another. There are three different categories of parameter settings depending on the mix of application modules being utilized:
Category I |
Category II |
Category III |
FI and GL |
CO, FI and GL |
CO, AM and HR |

The profile parameter settings for each category are specified below for both basic and extended maintenance. For basic maintenance, enter the parameter name in the right screen. For extended maintenance, enter the actual parameter name in the profile. The following table labels parameters which cannot be set using basic maintenance as N/A (not applicable).
For system profile parameters, you should use the standard values proposed by the system. The preset values are valid for almost all cases. You should only change the parameter values with the prior agreement of SAP or a SAP partner.
Technical information for a parameter is provided by the system. Choose F1 to display documentation for the parameters that appear in the current profile.
