SAP Table Logging
Will 'SAP table logging' on one table cause a performance problem?
In what transaction code would I turn on SAP table logging (auditing)?
I don't think that you will face with a performance problem, by activating logging mechanism on TCURR table. Keep in mind that if you are planning to activate the logging mechanism over a transaction table such as VBRP or LIPS, you may face with the performance problem.
The performance problem aside, take into account that DBTABLOG table may be fill up.
