TutorialKart.comIn this SAP PM tutorial, you will learn how to assign order types to a maintenance planning plant in SAP using transaction code OIOD. This Customizing step makes a maintenance or service order type valid for a planning plant, so users can create PM orders for that plant without order-type support errors.
Assign order types to planning plant in SAP PM with OIOD
In SAP PM, order types are configured separately and then assigned to the maintenance planning plant where they are allowed to be used. If the assignment is missing, the order type may exist in the system, but SAP will still block it for the selected planning plant during maintenance order creation or related processing.
A common message in this situation is:
Order type xxxx is not supported for planning plant XXXXThis assignment is especially important when a company uses different planning plants, different maintenance order types, or plant-specific maintenance processes.
When the OIOD planning plant assignment is required
Use transaction OIOD after the required maintenance order types are already created. The activity is normally part of SAP PM order type configuration and is completed before functional users create maintenance orders in transactions such as IW31.
- Use it when a new maintenance planning plant is created and needs valid PM order types.
- Use it when a new PM order type is configured and must be available for one or more planning plants.
- Use it when order creation fails because the order type is not supported for the selected planning plant.
- Use it when different plants should use different allowed maintenance order types.
Prerequisites before assigning PM order types to planning plant
Before you maintain this assignment, confirm the following points. This avoids saving incomplete configuration or assigning the wrong order type to the wrong planning plant.
- The maintenance planning plant has already been maintained in SAP.
- The required order type has already been created and configured for maintenance processing.
- You know whether the assignment is for a planning plant, not merely the physical maintenance plant.
- You have the required Customizing authorization and a transport request, if your system records configuration changes in transports.
OIOD transaction and IMG path for assigning order types to maintenance plants
Navigation
| Transaction Code | OIOD |
| SAP IMG Path | SPRO > IMG > Plant Maintenance & Customer Service > Maintenance and Service processing > Maintenance & service orders > Functions and Settings for order types > Assign order types to maintenance plants. |
You can open the activity directly with transaction code OIOD, or follow the IMG path in SPRO. Both options open the same Customizing activity for valid order types by planning plant.
OIOD configuration steps to assign an order type to a planning plant
Perform the following configuration steps for assignment of order types to maintenance planning plants in SAP.
Step 1 : – Execute t-code “OIOD” in SAP command field and press enter to continue.
Step 2 : On change view valid order types by planning plant overview screen, choose new entries button for assignment order types screen.
Step 3 : On new entries assign valid order types screen, update the following details.
- PlPL : Update the maintenance planning plant key for assignment to order type.
- Type : Update the order type key for assignment.
- After updating the planning plant and order type, press enter to continue. Now the name 1 and order type text will be automatically updated by the SAP System.
Choose save icon and save the configured assignment details.
Successfully we have assigned order types to maintenance planning plant in SAP.
Field meaning on the valid order types by planning plant screen
| Field | Meaning in OIOD | How to maintain it |
|---|---|---|
| PlPl | Maintenance planning plant for which the order type will be valid. | Enter the planning plant key, for example the plant responsible for planning maintenance work. |
| Type | Maintenance or service order type allowed for the planning plant. | Enter the order type key that has already been created in PM order type configuration. |
| Name 1 | Description of the planning plant. | SAP fills this value automatically after you press Enter, if the plant master data is available. |
| Order type text | Description of the selected order type. | SAP fills this value automatically from the order type configuration. |
If the description fields do not populate after you press Enter, recheck the planning plant and order type keys. A wrong key usually indicates that the prerequisite plant or order type configuration is incomplete or that the value was typed incorrectly.
How to test the SAP PM order type assignment after saving
After saving the OIOD assignment, test the configuration with a maintenance order creation scenario. A simple check is to open transaction IW31, enter the same order type and planning plant, and continue with the order data. If the order type is valid for the planning plant, SAP should allow you to proceed to the order screen, subject to the rest of the order configuration and master data.
- If SAP still shows the message that the order type is not supported for the planning plant, return to OIOD and verify the exact PlPl and Type combination.
- If the order type is accepted but another error appears, continue troubleshooting the specific missing setting, such as number range, settlement profile, work center, notification type linkage, or plant data.
- If the configuration is in a development client, confirm that the assignment was saved into the correct transport request before moving it to quality or production.
Planning plant versus maintenance plant in order type assignment
The OIOD screen uses the planning plant for the order type assignment. In SAP PM, the planning plant is responsible for planning maintenance tasks, while the maintenance plant is where the technical object or maintenance work is physically located. In many systems both may be the same plant, but they can also be different. Always confirm which planning plant is used on the maintenance order before assuming the assignment is missing.
This distinction is important in multi-plant maintenance scenarios. For example, one central planning plant may plan work for several maintenance plants. In that case, the order type must be valid for the planning plant used in the maintenance order.
Common OIOD errors while assigning order types to planning plant
| Issue | Likely reason | What to check |
|---|---|---|
| Order type is not supported for planning plant | The PlPl and Type combination is not maintained in OIOD. | Add the exact planning plant and order type combination, then save and retest. |
| Description fields do not appear | The planning plant or order type value may be invalid. | Check whether the plant and order type exist and are typed correctly. |
| Order creation reaches another configuration error | OIOD is correct, but another PM order type setting is missing. | Review number ranges, settlement settings, default values, and other order type functions. |
| Configuration works in development but not in production | The transport may not have been moved, imported, or included correctly. | Check the transport request and import status in the target system. |
T357 table question and the OIOD assignment
Some learners search for table names while checking this configuration. Table T357 is generally associated with plant section data in SAP PM, not with the OIOD assignment of valid order types to planning plants. For this activity, use transaction OIOD or the IMG path rather than trying to maintain technical tables directly. If a table-level check is required in a project, confirm the relevant view or table name in your own SAP release with SE11 or with your SAP basis/functional team.
Configuration review checklist for SAP PM order type planning plant assignment
- The planning plant entered in PlPl is the same planning plant used during PM order creation.
- The order type entered in Type is already configured as a maintenance or service order type.
- The description fields populate after pressing Enter, confirming that SAP recognizes both keys.
- The assignment is saved in the correct client and captured in the correct transport request where required.
- A test order in IW31 can proceed with the assigned order type and planning plant.
FAQs on assigning SAP PM order types to planning plant
How do I assign an order type to a plant in SAP PM?
Use transaction OIOD or follow the SPRO path for assigning order types to maintenance plants. Choose New Entries, enter the planning plant in PlPl, enter the order type in Type, press Enter to validate the descriptions, and save the assignment.
Why does SAP show “Order type is not supported for planning plant”?
This message appears when the order type is not assigned to the planning plant used in the maintenance order. Maintain the correct PlPl and Type combination in OIOD, save it, and then retest the order creation.
What is IW31 in SAP PM and how is it related to this setting?
IW31 is used to create a maintenance order in SAP PM. When you create an order, SAP checks whether the selected order type is allowed for the planning plant. The OIOD assignment helps this validation pass for the correct plant and order type combination.
Is T357 the table for assigning order types to planning plant?
No. T357 is generally used for plant section data in SAP PM. For assigning valid order types to planning plants, use transaction OIOD or the related IMG activity instead of maintaining T357.
Can the same SAP PM order type be assigned to multiple planning plants?
Yes. If the same order type should be used by multiple planning plants, create separate OIOD entries for each planning plant and order type combination, then save the configuration.
Result of assigning order types to maintenance planning plant
After the assignment is saved, the selected maintenance or service order type becomes valid for the specified planning plant. Users can then create or process PM orders with that order type for the planning plant, provided the remaining order type and master data settings are also complete.
