Hi Yingqi,
no, what you got was the eclipse error log.
In ABAP in Eclipse, over "Window" -> "Show view" -> "Other ..." -> "ABAP Log", you can switch the ABAP log visible.
The activation log is the DDIC protocol during creation/activation of an object, which shall be showed in ABAP Log view.
Also, please check the data type and length in your table definition. In eclipse help of ABAP in Eclipse or ABAP online help you can find the supported HANA date type for ABAP DDIC.
Regards,
Hong
