Select the “Edit Configuration Changes” link at the bottom of the “Create Maintenance Change Request”, “Edit Maintenance Change Request” or “Revise Maintenance Change Request” page.

The “Edit Configuration Change Information” page appears.

The system displays the following fields in the “MCR Details” group box:

MCR #	The number identifying the MCR for which the configuration change information must be specified.
Revision #	The revision number of the MCR, if any.
Subject	The textual description of the MCR.
Source Doc Type	The type of the source document to which the MCR belongs.
Part Identifier	The identifier of the part as defined in the “Create Maintenance Change Request” page, which could be one of the following:
	Internal - indicates that the MCR must be executed on the part which is already available with the operator. This internal part is already defined in the "Create Parts Main Information" activity of the "Part Administration" business component.
	Supplier - indicates that the MCR must be executed on the part supplied by the supplier. This part can be a new part or an alternate part that is defined in the "Maintain Alternate Part Nos" activity of the "Part Administration" business component.

Enter the following field in the “Group Details” group box:

Applicability Group #

Use the drop-down list box to select the group of aircraft, component or engine for which the MCR is applicable. The system lists the group numbers created in the “Aircraft Effectivity” page if the MCR is applicable for “Aircraft” or the group numbers defined in the “Component Effectivity” page if the MCR is applicable for “Component” or “Engine”.

Leave this field blank, if you wish to enter the configuration change details with respect to the MCR and revision number combination.

Click the “Get Details” pushbutton to retrieve the configuration change details that have already been defined for the applicability group.
Enter the following field:

Default Stock UOM

Check this box if you wish to specify the stock UOM for the part numbers. If this box is checked the system saves the stock UOM defined for the part in the “Part Administration” business component on clicking the “Edit Configuration Change Information” pushbutton.

The system displays the multiline fields if the configuration change details have already been defined for the applicability group.

Enter the following fields in the “Part Accountability Details” multiline to record configuration changes:

Existing Part #

The part that must be replaced (Alphanumeric, 40). Mandatory. Ensure that this part is not defined as part accountability in any other applicability group.

Help facility available.

Part Description	The textual description of the part (Alphanumeric, 150).
UOM	Use the drop-down list box to specify the unit of measurement for the part. The system lists all the UOMs in “Active” status that are defined in the “UOM” business component and sets the field to blank by default. Selection of value in this field is mandatory if you have entered the part number or quantity and not checked the “Default Stock UOM” box.
Quantity	The number of parts that must be changed (Integer). Mandatory. Ensure that the value that you enter in this field is positive.
Recommended Use	Use the drop-down list box to specify the action recommended for the part that should be replaced. The system provides the following options:
	Discard – Select this option to indicate that you can discard the part.
	Rework – Select this option to indicate that you can rework on the part
	Others – Select this option to indicate that you can keep the part for other purposes.
New Part #	The new part number that will replace the existing part (Alphanumeric, 40). Mandatory. Help facility available.

Note: If the new part numbers have already been defined as the configuration change information, then the system displays the part numbers in the above field.

Part Description	The textual description of the new part (Alphanumeric, 150). Mandatory.
Quantity	The number of parts that will replace the existing part (Integer). Mandatory. Ensure that the value that you enter in this field is positive.
Interchangeability	Use the drop-down list box to specify the part interchangeability. The system provides the following options:
	One Way – Select this option to indicate that the part numbers are not interchangeable in the same position code. For example, if the part number “P2” has replaced the part “P1” in the position code “PC1”, then “P1” cannot replace the part “P2” subsequently in the same position code.
	Two Way – Select this option to indicate that the part numbers are interchangeable in the same position code. For example, the part numbers “P1” and “P2” can replace each other in the same position code subsequently.
	None – Select this option to indicate that "P1" cannot be replaced by "P2".
	By default, this field is set to “None”.
Remarks	Any comment or remark pertaining to the configuration change (Alphanumeric, 255).

Note: Ensure that the combination of the existing part number and the new part number is unique in the multiline.

Check the box in the “Select” column of the multiline to mark the part number for deletion.
Click the Delete icon in the tool bar above the multiline, to delete the part numbers selected in the multiline.
Click the “Edit Configuration Change Details” pushbutton to update the configuration change information.

Specifying configuration change details for the MCR – An overview

The MCR execution might affect the configuration of the aircraft model or the aircraft. This change in configuration might result in the change of the part number resulting in a new part number, change in the interchangeability rules for a particular position in the model / aircraft, addition of a new position code, etc. These details are recorded as configuration change information in this page.

You can specify the part number that is changed, its description, unit of measurement, the number of parts changed and the recommended action for the changed part number. Also, you can enter the new part number, its description, the number of parts that replaced the previous parts, the part interchangeability and remarks regarding the configuration change. You are also provided with the option of specifying the default Stock UOM defined for the parts in the “Part Administration” business component.
