The "Write to Data Store" smart service is configured to write data to a specific database table, which is represented in Appian as a data store entity. The node requires two primary configurations on its Data tab:

1. The target Data Store Entity must be selected. This tells Appian which table to write to.

2. The data to be written must be provided in the Value to Store input. This input must be a process variable of the corresponding Custom Data Type (CDT), in this case, ACMEvideo.

A. You provide the data as a single variable of the CDT type, not as separate inputs for each individual field of the CDT.

C. This is imprecise. You must specify the specific data store entity (the table), not just the data store (the database connection).

1. Appian Documentation, "Write to Data Store Smart Service": Under the "Data Tab" section, the documentation specifies the configuration. It states that a "Data Store Entity" must be selected from a dropdown list. It also details the "Value to Store" input, which is defined as "The data to be stored... based on the CDT you've mapped to your data store entity." This confirms that both the entity and a CDT-typed input are required.

2. Appian Academy, "Appian Developer" Learning Path, "Data with Appian" Course: The module on "Writing and Deleting Data" demonstrates the configuration of the Write to Data Store smart service. The instructional videos and materials show that the developer first selects the target data store entity and then maps a process variable of the corresponding CDT type to the node's "Value to Store" input.
