SAP Error Message - Details

• Message type: E = Error

• Message class: 29 - Bills of Material

• Message number: 018

• Message text: BOM is allocated to other plants

What causes this issue?

You want to change the bill of material.
As this BOM is allocated to other plants, the changes become effective
in all the plants to which the BOM is allocated.
You see this warning message because the system makes the required
checks (such as checking for a material master) in all the plants, and
the change you want to make may be rejected. This would be the case,
for example, if the material master for a new material item is not
maintained in all plants.

If you want to make the change, confirm this warning message.

• What is the cause and solution for SAP error message 29018 - BOM is allocated to other plants ?

  The SAP error message 29018, which states "BOM is allocated to other plants," typically occurs when you are trying to create or modify a Bill of Materials (BOM) in a plant where the BOM is already allocated to another plant. This can happen in various scenarios, such as when you are trying to create a BOM for a material that already has a BOM assigned to a different plant.
  Cause:
  
  BOM Allocation: The BOM you are trying to create or modify is already assigned to a different plant. In SAP, BOMs can be plant-specific, meaning that each plant can have its own BOM for the same material.
  Material Master Settings: The material may have been set up in such a way that it is linked to a specific plant, and the BOM is not allowed to be shared across plants.
  Data Entry Error: There may be a mistake in the plant code or material number being used, leading to the system not recognizing the intended plant for the BOM.
  
  Solution:
  
  Check Existing BOMs: Use transaction code CS03 (Display BOM) to check if a BOM already exists for the material in another plant. If it does, you may need to either modify that BOM or create a new BOM for the intended plant.
  Create BOM for the Correct Plant: If you need to create a BOM for a different plant, ensure you are using the correct plant code when creating the BOM. Use transaction code CS01 (Create BOM) and specify the correct plant.
  Copy BOM: If you want to use the existing BOM as a template, you can copy it to the new plant using transaction code CS01 and selecting the "Copy" option.
  Check Material Master: Ensure that the material master data is correctly set up for the plant you are working with. Use transaction code MM03 (Display Material) to verify the settings.
  Consult with SAP Basis or Functional Team: If you are unsure about the settings or if the issue persists, consult with your SAP Basis or functional team for further assistance.
