SYMPTOMS
Extender information is populated on a transaction, and then saved to a batch. When the batch is posted in Microsoft Dynamics GP 10.0, the Extender data is removed from the EXT00100 table.
CAUSE
The Extender data is removed from the EXT00100 table because the Extender Window has a Table Link to a Work table. As soon as the transaction is posted, it is no longer in the Work table and will be removed from the EXT00100 table.
RESOLUTION
Instead of a Table Link to a Work table, you must link to a History table. The Extender data will only be removed from the EXT00100 table if the transaction is removed from history.
