After a relational table is associated with a database, you cannot edit the mapping while the association is still in place. To make an edit to the mapping in Acoustic Campaign, use an API call disassociate a relational table from a database and then edit the mapping. Alternatively, you can delete the table and start over from the beginning.
Here is an example of an API call.
<Envelope> <Body> <JoinTable> <TABLE_ID>xxxxxxx</TABLE_ID> <LIST_ID>xxxxxxx</LIST_ID> <REMOVE/> </JoinTable> </Body> </Envelope>
If you need to un-map or disassociate a relational table from a database and associate it with a new database, you can do so by using the <REMOVE>
element within the JoinTable API call.
