今日阅读邮件，发现了一个跟踪：performance analysis。（St05）。也许有用，记录如下：
Q：I uploaded data through BDC from Excel file using transaction MM01. How
can we know in how many tables the data is going ? Also how can we get
the name of those tables ?
A：Best option is to use ST05 SQL trace: activate the trace, run the BDC,
deactivate the trace and then display it. In the detail overview you can
also see the type of operation on the table (update, insert etc)
Check the menu functions; there are options to get an aggregated
overview of tables 。
