The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

You are attempting to create a procurement alternative for material
&V1& in plant &V2&. This material is either a phantom assembly or it is
reserved in the other plant.
Although mixed cost estimates can be created for materials with these
special procurement types, there is no rollup of the mixed cost
estimate. The procurement alternatives costed, however, are rolled up.
Example: Mixed cost estimate of materials 'FERT', 'Phantom Assembly'
and 'HALB'.
FERT

• What is the cause and solution for SAP error message CKBA164 - Material & & is a phantom assembly or is reserved in other plant ?

  The SAP error message CKBA164 indicates that the material in question is either a phantom assembly or is reserved in another plant. This error typically arises during the process of creating or processing a bill of materials (BOM) or during production planning and execution.
  Causes:
  
  Phantom Assembly: The material is defined as a phantom assembly in the system. Phantom assemblies are used in BOMs to simplify the structure and are not stocked as separate materials.
  Reservation in Another Plant: The material is reserved for use in another plant, which means it cannot be used in the current plant until the reservation is released or the material is made available.
  
  Solutions:
  
  
  Check Material Master Data:
  
  Verify if the material is indeed defined as a phantom assembly. You can do this by checking the material master data in the SAP system.
  If it is a phantom assembly and you need to use it, consider whether you can adjust your BOM or production order to accommodate this.
  
  
  
  Check Reservations:
  
  Use transaction codes like MB22 (Change Reservation) or MB23 (Display Reservation) to check if there are any existing reservations for the material in other plants.
  If there are reservations, you may need to either wait for them to be released or adjust your planning to use a different material.
  
  
  
  Adjust BOM:
  
  If the material is a phantom assembly and you need to create a BOM, consider restructuring the BOM to remove the phantom assembly or replace it with a stocked item.
  
  
  
  Consult with Production Planning:
  
  If you are unsure about how to proceed, consult with your production planning team or the person responsible for BOM management. They can provide insights into how to handle phantom assemblies and reservations.
  
  
  
  Check Plant-Specific Settings:
  
  Ensure that the material is correctly set up for the specific plant you are working in. Sometimes, materials may be available in one plant but not in another due to configuration settings.
  
  
  
  Related Information:
  
  Phantom Assemblies: These are typically used in complex BOMs to reduce the number of levels in the BOM structure. They are not physically stocked but are used for planning purposes.
  Material Reservations: These are used in SAP to allocate materials for specific production orders or projects. Reservations can be plant-specific, and managing them effectively is crucial for production planning.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM
  MB22: Change Reservation
  MB23: Display Reservation
  
  
  
  By following these steps and understanding the context of the error, you should be able to resolve the CKBA164 error effectively.
