- Materials cannot be allocated to sub-operations ?The SAP error message IW122, which states "Materials cannot be allocated to sub-operations," typically occurs in the context of production orders or maintenance orders when there is an issue with the allocation of materials to specific sub-operations within a work order. Here are the common causes, potential solutions, and related information for this error:
Causes:
- Missing Material Master Data: The material may not be properly defined in the material master, or it may not be set up for the specific plant or storage location.
- Incorrect BOM (Bill of Materials): The BOM for the operation may not include the required materials, or the components may not be correctly assigned to the sub-operation.
- Stock Availability: There may not be enough stock available for the materials required for the sub-operation.
- Incorrect Work Center Settings: The work center associated with the operation may not be configured correctly to handle the materials.
- Status of the Order: The production or maintenance order may be in a status that does not allow for material allocation (e.g., if the order is already completed or closed).
- Material Type Restrictions: The material type may have restrictions that prevent it from being allocated to the operation.
Solutions:
- Check Material Master Data: Ensure that the material is correctly set up in the material master, including the necessary views (e.g., basic data, purchasing, and accounting).
- Review BOM: Verify that the BOM is correctly defined and that the materials are assigned to the correct operations and sub-operations.
- Check Stock Levels: Use transaction codes like MB52 or MMBE to check the stock levels of the required materials. If stock is insufficient, consider creating a stock transfer or procurement order.
- Validate Work Center Configuration: Ensure that the work center is correctly configured to handle the materials and that it is active.
- Order Status: Check the status of the order. If the order is in a status that does not allow for changes, you may need to change the status or create a new order.
- Material Type Settings: Review the material type settings in the configuration to ensure that there are no restrictions preventing allocation.
