Task Application Property

Assigning Transactions to Tasks

When you associate a Transaction object to a Task take into account that only one record can be modified during the task execution.

If you navigate through the records with the Transaction object and try to update another Key values the following error will appear

Please 'Get' data before trying to update it

When the task relevant data is mapped to the Transaction primary key and values arre not null; the Transaction is executed using Update mode; otherwise Insert mode is used.

When the Transaction uses the parm rule; it is expected to use one parameter for each attribute of the Primary Key, with the same name, and an additional Mode parameter. In that way, GXflow client will execute the Transaction assigning those parameters with the relevant data mapped to the primary key.
