Signavio process intelligence extraction error with VBRP

Hi,

We are trying out the process intelligence on SD tables/process, we encounter error log with message

The field of type BINARY is not supported. Caused by

Key -2 is missing in the map.

we have no issue with VBAP, but somehow VBRP is not working, below is the preview screen

Any advice is welcome, as we are new to this product.

Thanks

Wings
