Table 1-9 Supported functions (continued)

start – Integer that specifies where the substring starts.

length -- Integer that specifies the length of the substring.

Example SUBSTRING(%_CUSTOMPROMPTS_PHONE_%, 3, 7)

Sample expressions:

String evaluation

%_AUTHENTICATION_USERNAME_% = ‘johndoe’

%_AUTHENTICATION_USERNAME_%> ‘j’

%_AUTHENTICATION_USERNAME_% LIKE ‘john%’

TRIM(%_AUTHENTICATION_USERNAME_%) = ‘johndoe’

LEN(%_AUTHENTICATION_USERNAME_%) > 5

Logical operands and nested expressions

(expression) AND (expression)

(expression) OR (expression)

NOT(expression)

(((expression) AND (expression)) OR (expression)) AND (NOT(expression))

1.4.7.2 Graph conditional behavior

For navigation purposes, HP Embedded Capture evaluates the conditions of the connectors that navigate to

other nodes. Once evaluated, there are different situations, depending on the amount of possible nodes we

can navigate to. In the following sections we will analyze the different cases.

No possible nodes

This case is considered an exit point. Once there are no more nodes to display or to navigate, HP Embedded

Capture will consider the workflow complete, and the application will exit to the Home screen on the control

panel.

Single node

HP Embedded Capture will navigate to the next node and execute it as usual (screen or displayed nodes with

a screen, and processes will be executed).

Multiple nodes

HP Embedded Capture will display all possible nodes that can be navigated to, after having evaluated their

navigation conditions. In this case, it will be represented as a menu screen where the menu options are all the

available nodes.

1.4.7.3 Failover destination (process conditions)

A failover destination with conditions and metadata can be created.

The status of a process can be SUCCESS or FAIL. Depending on this value, conditions can be defined to

redirect the different workflow conditions to the appropriate nodes to send the documents to another

alternate destination.
