You have defined SAP-Schema types via XML-Schema extensions, which gets their object list from a table function, but the respective objects have to be read by a BAPI-Call. On reload, the data which stem from the table function are not anymore in the data object. But the schema of such an object reconciles the properties from table and BAPI-Return-Structure in such a way that the data from the table function must be preserved.
This will be fixed on a future release of the product. If you require this immediately corrected, please contact support for a hotfix referencing the defect ID 25568.
