CMC Profiles

Use

You can configure the CMC for specific users and work centers. You do this in the Customizing for the CMC profile by setting general parameters that affect the display, calculation, rotable control mode, and other advanced settings of the CMC on client level. Users and work centers can access these CMC profiles on the CMC selection screen.

A link between the CMC profile and the CMC selection screen exists. This means that parameters and select options concerning values found in the CMC profile are filled dynamically on the selection screen based on the CMC profile you select.

Caution Caution

You can overrule the CMC profile in the CMC selection screen . However, if you have created a selection variant the system uses the CMC profile parameters and not the selection variant parameters. To overrule this you must enter the values that you require in the relevant field each time, or change the Customizing settings accordingly. If you have no authorization for Customizing, contact your system administrator.

End of the caution.

Features

CMC display parameters

In this area, you define what you want to display in the CMC. You can select the types of orders that you want to see in the CMC, whether you want to display notifications, and whether you include completed operations.

You can also select a default CMC user status profile to determine which user status folders the CMC shows.

Moreover, you can select the default call mode for the CMC, defining whether the CMC performs all calculations, scheduling, and alert monitoring; just calculations and alert monitoring; or only displays information without CMC functionality.

CMC calculation parameters

In this area, you can select whether you want to include purchase orders, purchase requisitions, and work in progress (WIP) in the calculation of the stock-based priority value and the range of coverage (ROC) calculation.

You also define the factory calendar to be used in the ROC calculation . You should select a seven-day, 24 hour calendar for this calculation. This calendar is in addition to the plant-specific factory calendar that the system uses to schedule and prioritize orders.

An important function is the automatic priority switch. If you set this indicator, the CMC automatically switches from a stock-based priority calculation that is based on a reorder point to a time-based priority calculation when stock levels fall below the defined value. This enables the CMC to better prioritize components that have a low reorder point.

General rotables control

In this screen area, you can set defaults to determine how you define the condition of rotable parts (for example, serviceable, unserviceable, and so on). You can select from classified batches, storage locations, or split valuation. If you use storage locations and valuation types, you have to set up inventory groups in Customizing.

You can also define a target range of coverage (ROC), which determines that the CMC calculates against a safety stock level instead of a zero-level or negative stock.

The CMC profile also contains the general default parameters used in the ROC calculation . These parameters define the number of periods backwards the CMC should search for goods movements, the number of periods forwards the CMC should search for receipts, the maximum length of time a component may remain in the workshop in unserviceable condition, and the initial ROC value that the CMC should use in the ROC calculation if the calculation fails for new parts that have not yet been consumed. The CMC only uses these default values if it cannot find corresponding values on FFF class level or on inventory group level.

Note Note

The ROC calculation first searches for an FFF class. If unsuccessful, it then searches for an MPN set, as a last resort it searches for an individual MPN.

For this reason, the ROC calculation first looks for ROC parameters on FFF class level, then on plant level (CMC inventory group), and then on a general level (CMC profile).

End of the note.

If you use classified batches for rotable control and you do not want to use the default class AD_ROT001 in class type 022 and characteristic AD_ROTZUSTD , you can define your own class and characteristic to be used by the CMC. Note, however that the class must belong to class type 022.

Caution Caution

You cannot define the class and characteristic in CMC Customizing. If you want to use your own class and characteristic, you must use the current settings in your productive system and class type 022. You define your customer-specific class and characteristic under Start of the navigation path Logistics Next navigation step Plant Maintenance Next navigation step Maintenance Processing End of the navigation path or Start of the navigation path Logistics Next navigation step Customer Service Next navigation step Service Processing End of the navigation path , then Start of the navigation path Rotables Management Next navigation step Component Maintenance Cockpit Next navigation step Current Settings for CMC Next navigation step Enter Specific Class for CMC Profile End of the navigation path . This activity should only be performed by expert users, because it is possible to change all default parameters in the productive system using this function.

End of the caution.

Advanced CMC settings

  • Changes and Authorizations (several different indicators)

You define whether users can make changes within the CMC, and whether users have to enter a password in a verification dialog box before making these changes. You can activate a dialog box for changes to user status, order code, priority value, and transport and wait time (TWT), as well as for the user buttons.

Note Note

There are five user buttons, which contain an empty function module (ADRT10_USER_BUTTON). You can program this function module to include up to five additional functions that you may require in the CMC.

End of the note.

If you have operations covering both labor and machine capacity, you can define whether you want the CMC to bundle these operations by selecting the indicator for the machine operation. This is an improvement to the standard PM/CS functionality, which only makes a 50/50 split of labor and machine operations when evaluating capacity. If you activate parallel operations, the CMC bundles these operations at runtime and sets the duration of both labor and machine to the duration of the longest operation. You can select the indicator for one or more machine operations if they are consecutive in the order.

Example Example

You have operations for labor and machine in work center A. The duration of the labor part is 3 hours, the duration of the machine part is five hours. You have selected the machine operation indicator in the order. At runtime, the CMC checks both and sets the duration of the total operation to five hours.

End of the example.

You may receive PM/CS orders with operations that are to be processed in different work centers. If the order has been created from different task lists, standard functionality does not consider transport time between the different work centers. Transport times may adversely affect order scheduling. For this reason, you can include Transport and Wait Time (TWT) in the CMC calculation by using the PP transport matrix. The CMC then considers these times when distributing the total available buffer.

Note Note

You must define standard and minimum transport times between the relevant work centers in PP Customizing. The CMC uses the default standard transport time. If you need to speed up the repair process, you can change this to the minimum transport time from within the CMC.

End of the note.

You define whether you want the CMC to process orders with relationships as one logical unit. This function internally bundles several orders for one logical repair process. Work centers often receive different orders that cover the same component. You can link these orders together using standard relationship functionality. If you activate the order link for the CMC, at runtime the CMC bundles the orders into one order internally using a unique internal number. The CMC groups the operations from these linked orders and schedules and prioritizes them together (depending on the Customizing settings for order codes and priority rules).

Caution Caution

The operations in the orders to be bundled must be numbered differently. For example, order XXX has operations 10, 20, and 40. Order YYY has operations 30 and 50. When linked, the CMC bundles XXX and YYY into an internal order ZZZ and puts all operations into the correct sequence - 10, 20, 30, 40, 50. If the operations in the separate orders are not numbered differently, the system outputs an error message and processes the orders individually.

End of the caution.
  • Aggregate operation sequence by work center

You can determine that the CMC merges all sequential operations that are in the same work center into one 'logical' operation. The CMC displays these 'merged' operations as one line in the CMC. If you do not select this indicator, the CMC displays each operation on a separate line.
