The content of a transaction list comes from the temporary table that is defined for the list. Any of the other tables used to populate the temporary table must be attached to the list form. Use the Form Definition window to attach these tables to the transaction list form.
For the Contact History list in the sample integration, the ContactHistoryTrxTemp table was created and attached to the ListObj_ContactHistoryTrx form. This is the main table that will be used to display data in the list. The IG_ContactHistory_MSTR table and the RM_Customer_MSTR table are also attached, since they contain the data that will be added to the temporary table for the list.
