You want to change the bill of material.

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.

• 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.
