Transaction Canceled CNV_MBT 326 ( 'Data Selection Start for All Tables' 0066 9#### 'Data Transfer'

Freinds:

I have fixed all previous issues that are caused by too many times of short dumps due to sender's DB is full.

Now the project itself seems is confused at the final moment of data selection (99% done).

the sympton is that whenever I restart data selection , it will abort without any short dump. The only meesage is at control system SM21:

Transaction Canceled CNV_MBT 326 ( 'Data Selection Start for All Tables' 0066 9#### 'Data Transfer').

CNV_MBT_STATE_AGENT_DTL K  SAP Web AS Problem SDYN

Extensive search on SMP and SDN did not come back with an fix.

Any idea?  Thanks!

P.S. We only have some remaining entries in following 2 tables to be selected.
