Dynamics AX Data Upgrade : Table mapping
During data upgrade the mapping algorithm follows the following precedence for source and target table mapping: 1. Check special mapping – this is custom mapping as defined within pre-synchronize scripts 2. Try to map by name, e.g. SalesLine -> SalesLine (Salesline table exist on both source and target system) 3. Try map by DEL_ prefix, e.g. SalesLine -> DEL_SalesLine (salesline table on traget doesn’t exist but DEL_Salesline table exists) 4. Try to map by ID (Salesline or DEL_salesline table on target doesn’t exist but the ID of the Salesline table on source and target is same) 5. Otherwise, mapping error is reported and must be fixed!
