M403: Settings: Strings in to which Business Data has been Inserted to be Set in Midstream

To configure pre-filled data in the Task Processing Screen (Input Screen), the method of Auto-Setting an [Initial Value] at the uppermost stream is useful. However, when it is necessary to refer to certain Business Data, the value must be set in the middle of the flow (Auto-Set Step).

1. Differences between Setting Initial Value and Generating Midstream with respect to String-type Data

a. Refer to the Business Data

You can refer to Business Data values (including [Issue Name]) when passing automated Steps

b. Need to recognize the risk of overwriting

The Data Item configured auto-set expression will overwrite the input value at the upper stream

c. Need to recognize the risk of collision processing

There is a possibility of conflicts in rewriting Data if the flow is split simultaneously

• Initial Value Settings do not allow Data that refers to other Business Data Items

2. Overview of the Purpose of Generating String-type Data Midstream

a. Avoid Double-Input

E.g. Inputting the deadline on both the "Payment Deadline" and "Invoice Guide" etc.

b. Prevent Transcription Error

E.g. Setting "Inquirer Name" in the "Body Text" or setting "Inquirer Address" in the "Reply Destination"

c. Prevent Variations in Notation Style

E.g. Set files name according to "Contract Type (Select-type)"

• The set Data will be copied when the issue passes through automated steps
• Even though the "Reference Source" is changed in the lower stream, the "Assignment Target" will not be modified cooperatively

3. Place Steps for Auto-Setting

1. Placing Data Setting Steps

Add [Service Task] steps into the flow

2. Adding Notes

Add Description notes on the input screen, such as "will be Auto-set/has been Auto-set"

• Instead of setting "Draft" as the [Initial Value], set it as a reference expression of [Service Task(Data Assignment)]
• In the lower stream give information to prevent parts that should not be modified from being edited by using "Input Hint"
