Scan events

The Scan Events configuration is no longer part of the general application settings of the Packaging Control client, but must be carried out in OpCon Server Systems (OSS). This configuration can be used to determine events that validate or modify the scanned data (e.g. cut off at end of CR LF) after the information has been received but not yet processed within an operation.

Available event sources:

Default
Default scan source that is processed during each scan operation.
Part
Processed if a part (product) has been detected.
Box
Processed if a box has been detected.
Pallet
Processed if a pallet has been detected.
SapSubHU
Processed if a SAP sub-HU (handling unit) has been uniquely detected.
SapMainHU
Processed if a SAP main HU (handling unit) has been uniquely detected.
AutomaticSetupStep1
Processed during the first stage of the automatic setup.
AutomaticSetupStep2
Processed during the second stage of the automatic setup.
AutomaticSetupStep3
Processed during the third stage of the automatic setup.
SapSubHUQuantity
Processed if the quantity of the SAP sub-HU (handling unit) has been uniquely detected.
SapMainHUQuantity
Processed if the quantity of the SAP main HU (handling unit) has been uniquely detected.
SapSubHUMaterial
Processed if the material (type) of the SAP sub-HU (handling unit) has been uniquely detected.
SapMainHUMaterial
Processed if the material (type) of the SAP main HU (handling unit) has been uniquely detected.
Gs1EpcGraiHex
Processed if a GS1 EPC GRAI (Global Returnable Asset Identifier) has been uniquely detected.
SerialNumber
Processed if a part (product) has been detected using the serial number.
SapSubHUBatch
Processed if the batch of the SAP sub-HU (handling unit) has been uniquely detected.
SapMainHUBatch
Processed if the batch of the SAP main HU (handling unit) has been uniquely detected.

If scanned parts (products) are to be detected generally as serial numbers (SerialNumber) and not as Part, it is necessary that the preceding check of the scan event Part always fails. This is achieved by configuring the scan event Part under Verification (RegEx) with the regular expression ^$ and checking Required.

The following table describes the settings for each event source.

If the Override Default option is activated, the event source Default is explicitly not processed.

Parameter Description

Parameter	Description
`Step`	Automatically created index of the verification/modification step.
`Text`	Descriptive text for the step.
`Verification (RegEx)`	The regular expression to verify the corresponding data (RegEx match).
`Modification (RegEx)`	AutomaticallyThe regular expression to modify the corresponding data (RegEx replace).
`String Extraction (start position)`	Specifies the zero-based character start position for a substring operation. #
`String Extraction (total length)`	Specifies the total length of the string to be extracted from the specified start position.
`Verify Required`	Determines whether the verification must succeed.
`Referenced Step`	An alternative verification step can be referenced here, which may be executed after the current step. The referenced step can in turn have an alternative verification step. This allows several verification steps to be linked together. Link options 1. AND link - The current and the referenced verification step have each set the `Required = true` parameter. In this case, both verification steps must be executed successfully. 2. OR link - The current and the referenced verification step have each set the `Required = false` parameter. In this case, one of the two verification steps must be executed successfully. See example below.

Step

Automatically created index of the verification/modification step.

Text

Descriptive text for the step.

Verification (RegEx)

The regular expression to verify the corresponding data (RegEx match).

Modification (RegEx)

AutomaticallyThe regular expression to modify the corresponding data (RegEx replace).

String Extraction (start position)

Specifies the zero-based character start position for a substring operation. #

String Extraction (total length)

Specifies the total length of the string to be extracted from the specified start position.

Verify Required

Determines whether the verification must succeed.

Referenced Step

An alternative verification step can be referenced here, which may be executed after the current step. The referenced step can in turn have an alternative verification step. This allows several verification steps to be linked together.
Link options
1. AND link - The current and the referenced verification step have each set the Required = true parameter. In this case, both verification steps must be executed successfully.
2. OR link - The current and the referenced verification step have each set the Required = false parameter. In this case, one of the two verification steps must be executed successfully. See example below.

Example of referenced step

Here, step 0 is executed first. If the verification is successful (scanned value must begin with S followed by nine numbers), step 1 is no longer executed. If the verification fails, step 1 is executed (scanned value must begin with 1JUN followed by 18 numbers). If this step also fails, the verification has failed. If one of the two steps is successful, the entire verification is successful.
