Data Collection Maintenance

You use this activity to define DC groups. DC groups contain data parameters that allow you to collect data values at various points in the manufacturing process. You can collect data for SFC numbers, work centers, and resources. For more information, see Data Collection (DC).

This activity allows you to do the following:

Create and change DC groups
Attach DC groups to various objects
Add custom data field for DC groups
Create and change data parameters
Assign logical limits for numeric data parameters
Assign an SPC chart for SPC analysis (see Statistical Process Control (SPC))

For more information, see Setting Up Data Collection.

Fields

The following tables describe fields requiring explanation:

Main Tab
Field	Description
Status	The status of the DC group Releasable: Users can use the DC group without any restriction. The DC group appears during data collection. New: Users cannot use this DC group, but they can change the record. It does not appear during data collection. Hold: Users cannot use this DC group. This status is temporary. Users can change the status of this record. A DC group with a status of Hold does not appear during data collection. Frozen: Users can use this DC group. The DC group appears during data collection. Obsolete: Users cannot use this DC group. This DC group is no longer used. It does not appear during data collection.
Collection Type	SFC: The collected parameter values are associated with an SFC number. Resource: The collected parameter values are associated with a resource. Work Center: The collected parameter values are associated with a work center.
Collect Data At	Defines when the data collection occurs during production. Start/Complete: Opens Data Collection Entry (DC500) when the user chooses the Start and Complete POD buttons (see POD Button Activities). Start: Opens Data Collection Entry when the user chooses the Start POD button. Note that DC500 must be assigned to the same POD button. Complete: Opens Data Collection Entry when the user chooses the Complete POD button. Note that DC500 must be assigned to the same POD button. Anytime: The user can enter parametric data values at any stage of the operation.
Collection Method	Identifies how the data is collected Manual – Single: The user enters data individually for each SFC number. Manual – Multiple: The user enters data once for a group of SFC numbers and the data parameter values are copied to each SFC number. For more information, see Approaches to Collection of Data.
ERP Group	If selected, data parameters of this DC group are sent to SAP ERP This checkbox is visible only if the ERP Integration Active system rule is set to true.
QM Inspection Group	If selected, this DC group is used for quality inspection. For more information, see Transfer of Production Order with Quality Inspection Lot. This checkbox is visible only if the ERP Integration Active system rule is set to true.
100% Quality Inspection	Automatically selected when the Required Number of SFCs value for each data parameters in this DC group equals the Build Qty value of the Production shop order. Sampling procedure for all inspection characteristics of this operation equals either 100% or ALLITEMS in SAP ERP (see Operations Inspection Charateristics Sampling procedure in transaction CA01). This checkbox is read-only and visible only if the ERP Integration Active system rule is set to true.
Evaluate Inspection Results	If selected, the data collected for this DC group is evaluated in SAP ME. SAP ME evaluates all 100% Quality Inspection DC groups. This checkbox is read-only and visible only if the ERP Integration Active system rule is set to true.
Pass/Fail Group	If selected, this DC group is a pass/fail group. If you select this checkbox, the system selects and disables the Override Min/Max checkbox on the Main tab page of the Parameter Detail screen.
Fail/Reject Number	Specifies how many normal parameters of the DC group must have values outside the minimum or maximum limits to fail this DC group. If this field is blank, all normal parameters must have values outside the minimum or maximum limits to fail this DC group. Note A DC group fails if at least one critical parameter has a value outside the minimum or maximum limits. A critical parameter has the QM Critical checkbox on the Main tab page of the Parameter Detail screen is selected. End of the note. When a DC group fails, SAP ME opens a nonconformance plug-in that is specified in the LOGNC_ID_ON_GROUP_FAILURE activity rule for DC500 (see Data Collection Entry)
User Authentication Required	If selected, users must identify themselves with the user name and password to enter data for this DC group.
Certification	Specifies that the indicated certification is required to enter data for this DC group

Main Tab on the Parameter Detail Screen
Field	Description
Sequence	The order in which data is collected when there are multiple data parameters to collect. If multiple data parameters have the same sequence number, they are collected in alphabetical order.
Parameter Name	The name of the information for which you are collecting data
Description	Describes this data collection parameter
Data Collection Prompt	The prompt that the production operator will see when collecting data. If blank, then the parameter name is used.
Status	Enabled: Allows the parameter to be used Disabled: Prevents the parameter from being used. If the parameter is disabled, it is not be displayed in the POD.
Allow Missing Values	Allows an operator to save the collected data for the DC group by entering a special character in place of missing values. The user can then use the DC Edit activity to replace the special character with a data value. The default character is M, unless defined differently in the LocaleSpecificText.properties file.
Display Data Values	If selected, the Type, Mask, Min Value, Max Value, and Unit of Measure field values appear in the DC Parameter list of the DC plug-in.
Type	Numeric: The type of the collected information is numeric. Boolean: The type of the collected information is boolean. The valid choices are defined in the 0 Value and 1 Value fields. For use with quality inspection, 1 Value means passed, 0 Value means failed. Note that selecting the Boolean option disables Min Value, Max Value, and Mask fields, and the Override Min/Max checkbox. Formula: The collected information is calculated according to the formula that the user enters (see Writing Formula Scripts). Note that selecting the Formula option activates the Formula button and disables the 0 Value and 1 Value fields. Text: The type of the collected information is textual but numbers are allowed. Note that selecting the Text option disables the Min Value and Max Value fields. Note that selecting the Numeric, or Formula options enables all the fields on the SPC tab page.
Override Min/Max	If selected, allows operators to save values that are beyond the range of the values defined in the Min Value and Max Value fields. Note that selecting this checkbox enables the Certification field.
Certification	Specifies that the defined certification is required to override the minimum or maximum value in the data collection field.
Soft Limit Check on Min/Max Value	If selected, allows operators to save values that are beyond the range of the values defined in the Min Value and Max Value fields Note that this checkbox is enabled only for the Numeric and Formula parameter types. Automatically selected for all data parameters of DC groups that are used for quality inspection. For more information, see Transfer of Production Order with Quality Inspection Lot.
Auto Log NC on Min/Max Override	If selected, the system automatically logs a specified NC code against an SFC number when the entered value for this data parameter is outside the maximum and minimum limits. If this checkbox is selected, Override Mix/Max becomes selected and disabled, and the NC Code field becomes a required field.
NC Code	The NC code that system automatically logs against the SFC number when the entered value for this data parameter is outside the maximum and minimum limits.
Min Value	The minimum value that an operator can save during the data collection. If blank, no minimum value restriction is placed on the data collected.
Max Value	The maximum value that an operator can save during the data collection. If blank, no maximum value restriction is placed on the data collected.
Mask	The metacharacter string of the mask The following metacharacters are valid: `@` (At sign): Any single alphabetic character (A through Z) `#` (Number sign): Any single digit (0 through 9) `^` (Carat sign): Any single hex character (0 through 9, A through F) `?` (Question mark): Any single alphanumeric character (0 through 9, A through Z) `.` (Period): A wildcard character that represents any single ASCII character `*` (Asterisk): Any number (including 0) of any characters. The asterisk can be used only once in the mask. `\` (Backslash): Allows other metacharacters to be used as literal characters. For example, to include the character @ in your mask, enter `\@`. Note Any other character in the mask is interpreted as a literal one. End of the note. For example, if you specify `@@###`, the following values are possible: AA123, XY001, or QW456. For more information, see Setting Up Mask Validation for Assembly Data Types.

Required	If selected, operators must enter numeric or textual data during data collection.

SPC Tab on the Parameter Detail Screen
Field	Description
Perform SPC Analysis	Selected: The SAP MII SPC engine is used to generate an SPC Chart and to perform trend rule analysis based upon the trend rule set assigned to the chart. SPC warning or violation messages are sent, if a trend rule is violated (see SPC Chart Maintenance and SPC Alarm Severity Maintenance). Deselected: The chart is not displayed during data collection, regardless of the setting for the Display Chart field below in this table, and no SPC analysis is performed.
Short Run	If selected, the user can enter the target value for each material for which data is collected for the chart. In the short run mode, data from multiple materials can be used in the same chart. Instead of using the actual measurement values, the deviation of each measurement value from the target (or nominal) value is used.
Display Chart	Never: SPC charts never appear during data collection. Always: SPC charts always appear during data collection. Only Alarm: SPC charts appear only when an SPC violation occurs (see SPC Alarm Severity Maintenance).
Expression Builder	Enables calculating the values collected for the SPC charts. For example, Log (@X), where the logarithm of the entered value is used. This field is visible only when Statit e-server software is used.
Check Syntax	Executes the Statit application to test the syntax of the expression entered in the Expression Builder field This field is visible only when Statit e-server software is used.
