Determinants in ProTrack Warehouse are triggerable contributers to an overall standard time.

To access the Maintain Determinant screen:

1. Log in to ProTrack Warehouse.

2. Select Determinant under the Standards menu. The Determinant screen appears.

Adding Determinants

You can add one or more new determinants into the system through the Determinants screen. The Determinant can be added based on the privileges of the user.

To add a new determinant:

1. Type a unique Determinant Name.
2. The Constant Standard Value is currently not supported. If this is required merely entire the value in the Work Time Function section.
3. If the KVI Entry screen will be used to specify KVI values for a field used in this determinant’s Work Time Function, enter the Maximum Allowable Key-In Units which a user may enter via at the time of entering KVIs.
4. Specify the Determinant Level as either Assignment Level or Task Level:
   
   Assignment Level Determinants:

• Only apply once per assignment, unconditionally (cannot have conditions).
• May be configured as either a Travel or Work determinant.
• Work Time Function may NOT include a field (variable), as assignment level determinants are not associated with a particular task line. The Work Time Function field does support functions of constants only (for example, 1.45 * 2).
  
  Task Level Determinants:
   
• Task Level will try to apply at each task line within an assignment based on the conditions.
• May only be configured as a Work determinant.

• Require at least one condition (even if that condition will always be true).

  Number of Task Level Determinants and Conditions has a direct impact on the overall performance (data throughput) of ProTrack Warehouse. Care needs to be taken to build only the determinants that are required to drive the granularity of Standard required for the activity. Assignment and Task Level Determinants are required for each Standard.

1. Click to apply or not apply Additional Handling.
2. From the drop-down list, select a Handling Matrix Name that was set-up in Handling Time.

3. Click one of the Determinant Type options to set the determinant type to either Travel or Work.
   
   

   Travel Determinants cannot be set to apply based on a specific set of conditions. These are used to hard-code a specific assignment Start, End, and Drop locations. Travel Determinants must be configured as Assignment Level.

4. If Determinant Type is set to Travel, specify the Start Location, End Location and Drop Location from their respective lists.
5. To specify the standard time for this determinant, enter a function into the Work Time Function text box. The function entered may be a simple constant value, or an algebraic expression.

   1. For expressions, you can use fields as variables. Click 'Insert a Field' link and a popup screen appears. Click a WMS Import field link, which is then populated in the Work Time Function field.
      
      
      ^{Fig.2 Determinant - Work Time Function}

       

      While saving, the system validates the work time function. When Work Time Function is defined it is necessary to list the fields within double quotations “ “, without which the formula will not be valid. The expression may be built using addition,subtraction, division, or multiplication operators: + - / * Also, parentheses may be used to specify order of operations: ( ). The total length of the work time function cannot exceed 80 characters. The formula can be an expression much like that used in Excel. Example: (“Quantity” * “Unit Weight”) * .0006 The formulas can generate a negative number if time needs to be reduced due to a specific task not being preformed on this specific assignment. Example: “Quantity” * -1.234 Total standard time for one assignment is 35,791 minutes (assume employee works eight-hour day this would allow 74 employees to work the same assignment). ProTrack Warehouse stores STD time in milliseconds and the max integer field in SQL Server 2005 is 2,147,483,647.

6. To add a condition to a determinant, click the 'Condition' tab. the screen appears with the Select Condition link and a blank ‘condition’ list.
   
   
   ^{Fig.3 Determinant - Conditions}

    

7. You can add the determinant conditions by clicking 'Select Condition' link.
   
   
   ^{Fig.4 Determinant - Selecting Conditions}

    

8. Select the check box of the individual Field Name.
   
   
   ^{Fig.5 Determinant - Selecting Fields}

    

9. Click  and the selected fields will be listed in the ‘Conditions’ list section of the Determinants screen.
   
   
   ^{Fig.6 Determinant - Conditions}

    

10. You can change the Condition Type for each Determinant Condition by selecting from the list.

• A specific Field Value is required for comparison when the Condition Type is:
  
  

  Condition Type	Description
  Equal To	Every time the field name’s value matches the field value, this condition is true.
  Greater Than or Equal To	Every time the field name’s value is greater than or equal to the field value, this condition is true.
  Greater Than	Every time the field name’s value is greater than the field value, this condition is true.
  Less Than or Equal To	Every time the field name’s value is less than or equal to the field value, this condition is true.
  Less Than	Every time the field name’s value is less than the field value, this condition is true.
  Not Equal To	Every time the field name’s value is not equal to the field value, this condition is true.
  On Change	Compares the current task line value of the field selected to the previous task line value and when the values are not the same, this condition is true.

  ^{Table 3. Condition Type Descriptions}

  The comparison is looking for an exact “case sensitive” match when alpha characters are used. Greater Than, Greater Than or Equal, Less Than, or Less Than or Equal conditions must be used on numeric fields. Example: Cannot compare Greater Than “C”. On Change conditions only applies within the same assignment, and thus cannot be used to trigger a determinant between assignments. When more than one condition is included in the same determinant, then all conditions must return true or the determinant will not apply. The “and” is implied between conditions.

  
  The following table lists all possible outcomes of the various Determinant Condition Types based on the type of data in the two fields being compared:
