Filling setup table: "DS 2LIS_02_SCL contains data still to be transferred"

We are tring to load Purchasing data from scratch. After conduct the setup table deletion through LBWG on Purchasing data, then run the setup table filling in, but after it's conducted, get the following msg at the status bar:

DataSource 2LIS_02_SCL contains data still to be transferred

Message no. MCEX024

What does that mean and how to resolve the fill in setup table problem? We searched on OSS Note and the msg no., but returns no result.

Thanks

I resolved the problem by myself.
