Search for new Tables and/or Table extractions are empty

After updating the SAP System, you get empty search results for SAP Object like tables, queries, repots etc. Also running extractions can be empty

This error comes up with some changes in the structure of the function module RFC_READ_TABLE in newer SAP Systems. 

Applying the SAP Note 2246160 into the SAP System (at least version 11 is needed) and update your Xtract or ERPConnect to the latest version solves this issue. The function module RFC_READ_TABLE in SAP gets corrected to the old behavior and is downwards compatible again.+
