Msi Missions Per Scenario

Training Manuals Alphabetical Function List Back Print this Topic Previous topicOne level upNext topic
Show/Hide Hidden Text

This function is used to define linked missions for a customer end item scenario.  This is done by, selecting predefined missions for maintenance significant items (MSI) in the product structure of the customer end item and defining the start/end dates and number of mission repeats for the selected scenario.

 

The purpose is to interact with other predefined data for the linked MSI missions, for example, failures per MSI mission, maintenance procedures etc. and to extract, for an end item scenario, the spares, skills, tools, facilities etc that could possibly be required during the duration of the selected scenario.

 

INQUIRE

The user must have a security profile linked to the function MSI Missions Per Scenario with an access allowed of Inquire.

 

On this tab the following fields can be viewed:

 

hmtoggle_plus1Apply

The user must have a security profile linked to the function MSI Missions Per Scenario with an access allowed of Change.

 

The "Apply" button is enabled when a mission is selected in the "Linked MSI Missions" list box I.E. the "Select" column of the line is ticked.  To change a linked MSI mission, change the mission repetitions, MSI sum qty per, start and end date details and click "Apply".

 

When the "Apply" button is clicked, mission repeats, composite quantity per, start date, and end date, on the Scenario MSI Mission table are updated for the selected scenario code, customer end item, serial number, MSI part number, and mission.

 

BUSINESS RULES WHEN UPDATING A LINKED MSI MISSION:

 

1.  A valid start date must be entered

2.  A valid end date must be entered.

3.  The mission repeats must be greater than zero.

4.  The scenario/customer end item combination must exist.

5.  The MSI/mission must exist.

6.  The MSI sum qty per must be greater than 0.

hmtoggle_plus1Available Msi Missions

When a customer end item is selected, the system checks details returned, from the Product_Str_Get_MSI_Mission stored procedure, against linked missions for each part and adds only missions which are not linked.

 

It is populated with the MSI part number, part description, MSI sum quantity per, mission, DOL units, part DOL, mission description, repetitions, sum quantity per, start date, and end date from the Scenario MSI Mission, MSI Mission and Part Master tables.

 

When "Select" is ticked the columns, Repetitions, Sum Qty Per, Start Date, and End date are enabled.  In order to link an available mission, values must be entered in these columns.

 

REPETITIONS

Repetitions indicates the number of mission repeats indicates how many times an MSI mission is going to be performed for a product use scenario.

 

This is used in the scaling exercise, together with failure rate and spare need percentage, to determine the amount of spares required to maintain a certain level of availability, for the customer end item during the scenario.

 

Mission repeats must be greater than zero and can handle 7 digits before and 2 digits after the decimal point.

 

SUM QTY PER

Indicates the summarised qty per of a MSI in relation to the end item specified when transaction SMMA (scenario mission maintenance) is done.

 

The MSI Sum Qty per is used to calculate the failure rate for an MSI.  The MSI Sum Qty per must be greater than zero and can handle 7 digits before and 3 digits after the decimal point.

 

START DATE

The Mission start date indicates the start of an MSI mission for the product use scenario.

 

This date is used to determine when spares and equipment are required for the scenario.  It must be a valid working day that is less than the end date specified.

 

END DATE

Mission end date indicates the end date for a MSI mission.   This date is used to determine when spares and equipment have to be returned.  It must be a valid working day that is greater than the start date specified.

hmtoggle_plus1Customer End Item

It is populated with the customer end item, the customer end item quantity, serial number, and description from the Scenario Structure table for the selected scenario.

 

By clicking on a customer end item in the list, the "Available MSI Missions" and the "Linked MSI Missions" list boxes are populated.

hmtoggle_plus1Link

The  button is enabled when the "Select" column is ticked in the "Available MSI Missions" list box and the mission repetitions, MSI sum qty per, start date and end dates are entered.

 

When the  button is clicked, the selected available MSI mission is added to the "Linked MSI Missions" list box.  The scenario code, customer end item, serial number, MSI part number, mission, mission repetitions, start date, end date, and the composite quantity per is inserted in the Scenario MSI Mission table.

 

BUSINESS RULES WHEN ADDING:

 

1.  The end date cannot be less than the start date.

2.  The mission repeats must be greater than zero.

3.  The scenario/customer end item combination must exist.

4.The MSI/mission must exist.
5.The sum qty per must be greater than 0.
hmtoggle_plus1Linked Msi Missions

It is populated with the MSI part number, part description, mission, DOL units, repetitions, mission DOL units, scenario DOL units, start date, end date, MSI sum quantity per, and mission description from the Scenario MSI Mission, MSI Mission and Part Master tables, for the selected customer end item, where the scenario code has missions linked to it.

 

When the "Select" column is ticked, you can adjust the values in the Repetitions, Sum Qty Per, Start Date, and End Date columns.

 

REPETITIONS

Repetitions indicates the number of mission repeats indicates how many times an MSI mission is going to be performed for a product use scenario.

 

This is used in the scaling exercise, together with failure rate and spare need percentage, to determine the amount of spares required to maintain a certain level of availability, for the customer end item during the scenario.

 

Mission repeats must be greater than zero and can handle 7 digits before and 2 digits after the decimal point.

 

SUM QTY PER

Indicates the summarised qty per of a MSI in relation to the end item specified when transaction SMMA (scenario mission maintenance) is done.

 

The MSI Sum Qty per is used to calculate the failure rate for an MSI.  The MSI Sum Qty per must be greater than zero and can handle 7 digits before and 3 digits after the decimal point.

 

START DATE

The Mission start date indicates the start of an MSI mission for the product use scenario.

 

This date is used to determine when spares and equipment are required for the scenario.  It must be a valid working day that is less than the end date specified.

 

END DATE

Mission end date indicates the end date for a MSI mission.   This date is used to determine when spares and equipment have to be returned.  It must be a valid working day that is greater than the start date specified.

hmtoggle_plus1Scenario

It is populated with distinct scenario codes and descriptions from the Scenario Structure and Scenario tables where:

 

The scenario code on the Scenario Structure table is equal to the scenario code on the Scenario table.

 

The number of characters to be entered before the list is shown is governed by the value of "populate length" (mandatory).

 

The scenario code is used to describe how the customer intends to use the end item.

hmtoggle_plus1Unlink

The  button is enabled when the "Select" column is ticked in the "Linked MSI Missions" list box.

 

When the  button is clicked, the selected linked MSI mission is removed from the "Linked MSI Missions" list box and inserted in the "Available MSI Missions" list box.

 

The scenario code, customer end item, serial number, MSI part number and mission are deleted from the Scenario MSI Mission table.
