Task 3: Create and Use a Maintenance Work Center
Objective
In Task 3, the requirement was to:
* create a new maintenance work center ZZ-ME42 for plant 1010 similar to T-ME00
* maintain the required capacity values
* create a 1-hour capacity demand for that work center by creating a maintenance order of type PM01



Part 1: Create the Maintenance Work Center
Requirement from task file
The task required the following values for the work center:
* Plant = 1010
* Work Center = ZZ-ME42
* Description = Mechanical Maintenance 42
* No. Ind. Capacities = 5
* Capacity = 24.00 H
The task also stated that the work center must be created similar to maintenance work center T-ME00 .

Step-by-step procedure
Step 1: Open work center creation
* Go to SAP GUI command field
* Enter transaction IR01
* Press Enter
Transaction IR01 is used to create a new work center. This is the correct starting point for creating the maintenance work center required in Task 3.
Step 2: Enter initial work center data
On the Create Work Center: Initial Screen , enter:
* Plant = 1010
* Work Center = ZZ-ME42
* Work Center Category = 0005
* In Copy from :
* Plant = 1010
* Work Center = T-ME00
Then press Enter .
The task explicitly required the work center to be created for plant 1010 and to be created similar to T-ME00.
Work center category 0005 is the maintenance work center category, so this was the correct category to use for a maintenance work center.
Step 3: Include capacity data during copy
When the Copy from popup appeared:
* select Capacities
* continue with the green check
This was important because the task required changing capacity-related data:
* No. Ind. Capacities = 5
* Capacity = 24.00 H Copying the capacity data ensured the new work center inherited the capacity structure from T-ME00 and could then be adjusted correctly.

Step 4: Maintain basic data
On the work center master screen:
* change the description to Mechanical Maintenance 42
This matches the exact description required by the task.
Step 5: Maintain capacity values
Go to the Capacities tab, then open the capacity detail screen.
Maintain or verify:
* No. Ind. Capacities = 5
* Capacity Base Unit = H
* Capacity recalculated to 24.00 H
In our system, the Capacity field was system-calculated and not directly editable.
The final valid values were achieved with:
* Start Time = 08:00:00
* End Time = 17:00:00
* Length of breaks = 01:00:00
* Capacity Utilization = 60
* No. Ind. Capacities = 5
This produced:
* Capacity = 24.00 H
The task required 24.00 H capacity, but SAP calculated it automatically based on operating time, utilization, and number of individual capacities.
The resulting calculation was correct and matched the task requirement exactly.
Step 6: Save the work center
* Click Save
Later, when trying to create the same work center again, SAP displayed the system message:
* "Work center ZZ-ME42 in plant 1010 already exists"
Explanation / Verification:
This system message confirmed that the work center had already been created successfully.
Therefore, the creation of ZZ-ME42 was verified as complete.
Part 2: Create a 1-Hour Capacity Demand
Requirement from task file
The task required:
* create a capacity demand of 1 hour
* for the newly created maintenance work center ZZ-ME42
* by creating a maintenance order of type PM01
Step-by-step procedure
Step 7: Open maintenance order creation
* In the command field, enter /nIW31
* Press Enter
Transaction IW31 is used to create a maintenance order.
The /n ensured SAP exited the previous transaction and opened the new one directly.
Step 8: Enter order header data
On the Create Maintenance Order: Initial Screen , enter:
* Order Type = PM01
* Planning Plant = 1010
Then press Enter .
The task explicitly required the capacity demand to be created by means of a maintenance order of type PM01 .
Step 9: Enter order description
On the order header screen, enter a short text such as:
* Capacity demand ZZ-ME42
The task did not prescribe a specific short text, so a meaningful description was used for traceability.
Step 10: Create the first operation
In the first operation area / operations overview, maintain:
* Operation = 0010
* Work Center = ZZ-ME42
* Plant = 1010
* Control Key = PM01
* Work Duration / Work = 1
* Unit = H
Then press Enter .
This operation is the actual source of the capacity demand .
The capacity demand is not created merely by the order header; it is created by assigning the operation to the work center with a planned work value of 1 hour .
Therefore, these operation entries were the critical part of fulfilling Task 3.

Step 11: Save the maintenance order
* Click Save
SAP displayed the confirmation message:
* "Order saved with number 4000314"
Explanation / Verification:
This was the final confirmation that the maintenance order had been created successfully.
Because the operation was assigned to ZZ-ME42 with 1 H planned work, this verified that the required 1- hour capacity demand had been created for the work center.
Verified completed objects
The following results were verified during execution:
* Maintenance Work Center created
* Work Center = ZZ-ME42
* Plant = 1010
* confirmed by SAP message that the work center already existed when rechecked
* Capacity maintained correctly
* No. Ind. Capacities = 5
* Capacity = 24.00 H
* Capacity demand created
* maintenance order type PM01
* operation assigned to ZZ-ME42
* planned work = 1 H
* Order successfully saved
* SAP confirmation: Order saved with number 4000314
