REC/CLIENT Parameter in the System Profile
Use
Systems
SAP recommends that automatic table change logging is authorized only in systems where this is worthwhile. These are generally the following systems:
Do not allow automatic logging in a test system.
Changes are not recorded during client copy. This wold impair performance and require considerable additional memory resources in the database.
Parameter Values
Table change logging is controlled by the rec/client parameter in the SAP system profile. The parameter can take the following values:
Parameter Value |
Meaning |
rec/client = off |
Table change logging inactive |
rec/client = all |
Table change logging active in all clients (See Warning below) |
rec/client = <client 1>... |
Table change logging active in specified clients |
Setting the REC/CLIENT parameter to All can seriously impair SAP system performance. SAP recommends you do not use the value All. You should limit automatic logging to one client.
The default setting is OFF, i.e. no logging. This setting is only normal in the installation and test phase. Tables which are relevant for invoicing should be logged in production processing (national accountability requirements).
The changes in a table are only logged automatically if:
Report RSPARAM displays all profiles in the system with their values.
