Data Entry Processing

Data entry processing (DEP) parameters are rules that define how data is entered into and processed by the POS terminal. An example that requires data entry processing configuration is triggering a function based on the data being entered.

Data entry processing options allow you to specify details for information that must be captured through a magnetic stripe reader (MSR), scanner device, or through keyboard entry at the POS terminal. You must define parameters to specify details such as the state of the POS terminal, how captured information is validated, and what, if any, subsequent functions should be triggered.

General
Description	Screen Element
Order	Order number of the DEP rule

This section provides information about the data entry process parameters.

Criteria
Description	Screen Element
POI State	State that the POI (point of interaction) must be in to accept the data entry
Worker Thread	Sets the rule to validate only if it is running from the off-thread process. Off-Thread processing is used for swipe-ahead debit and credit processing while in the process of scanning items (parallel processing). This option helps to indicate exactly when a rule can be run using the input data
Active Menu	Sets the rule to validate only if the menu ID matches the currently active menu on the POS terminal. It indicates exactly when a rule can be run using the input data
Transaction Type	Transaction that is affected by the data entry process
Validation Source	Device that reads the data source include the following: keyboard, scanner, magnetic stripe reader (MSR), customer MSR
Data Field	Extracts data that configures a specific value from the string of information that is read by the data entry device Note This is only available when the data entry source is a MSR device. For scanner or keyboard entered data, this field is populated with either scan data or keyboard data. No other selection options are available for scanner or keyboard entered data End of the note.
Scan Data Type	The symbol standard by which the scanned data is formatted, if the data being validated comes from a scanned source

This section specifies a function or a User-Defined Transaction (UDT) to start after receiving and validating entered data.

Primary Function
Screen Element	Description
Match Validation Rule	Validation rule that checks the received data. It specifies that entered data must match in order for it to be acceptable. Some of these are the expected length of the data, the check digit details, and the data validation parameters
Trigger Function	Starts the POS function selected when data is received and validated
Function Parameters	Details for the data to extract from information that the data source device provides

This section provides information about setting parameters for rules that have two possible functions.

Secondary Function
Screen Element	Description
Use Secondary	Displays the following secondary function options: Always — enables the function to take precedence Prompt — leaves the decision up to the cashier and displays prompts that have a choice selection
Prompt	Prompt type
Use Primary Response	Primary function when you enter a value
Use Secondary Response	Secondary function when you enter a value
Parameter	Sections of data to extract from the complete data when you provide field or parameter names Example To launch a Resume suspended transaction function from a bar code scan, the POS terminal extracts the Site ID, Device ID, and transaction number to identify and recall the transaction to resume End of the example.
Parameter Source	The source value is as follows: Fixed Value — value that is fixed Source Field — value that is from the source
From Data	Start position and maximum length of the section of data to extract. Data values to include are as follows: Start — start position of the data to extract. A start position of zero does not modify the data Length — length of data that is captured when you specify a value Decimals — decimal places that retrieve the value of a known decimal or field related to a dollar value type. This parameter is used for scanner data with embedded prices where you define the placement of decimal position
Strip Leading 0’s	Deletes the leading zeros from the number. It displays the final value as 1 for scanned barcode numbers such as 00001 that are padded with leading zeros
Append Data	Adds a prefix and suffix to data as follows: Prefix — value entered is added to the beginning of data Suffix — value entered is added to the end of the data Check Digit — lists all current check digit schemes
