How To Fix IS245 - Material number (&1) is not the same as the construction type (initial)

SAP Error Message - Details

• Message type: E = Error

• Message class: IS - Equipment management

• Message number: 245

• Message text: Material number (&1) is not the same as the construction type (initial)

What causes this issue?

Synchronous maintenance of material number and construction type are
recommended for the equipment type in Customizing, or to be precise: If
the material number is maintained, then the construction type should
have the same value.

System Response

The construction type of the equipment was not previously maintained.
The system indicates that to maintain synchronicity, you should change
the construction types to &V1&.

How to fix this error?

Check whether the construction type should be changed and, if
necessary, make these changes manually.

• What is the cause and solution for SAP error message IS245 - Material number (&1) is not the same as the construction type (initial) ?

  The SAP error message IS245 indicates that there is a mismatch between the material number and the construction type in the context of a bill of materials (BOM) or a related configuration. This error typically arises when the system expects a specific type of material based on the construction type defined in the system, but the material number provided does not conform to that expectation.
  Cause:
  
  Material Type Mismatch: The material number you are trying to use may not be compatible with the construction type defined in the BOM or the configuration settings.
  Incorrect BOM Configuration: The BOM may be set up incorrectly, leading to a mismatch between the material and the expected construction type.
  Data Entry Error: There may be a typographical error in the material number or the construction type.
  Master Data Issues: The material master data may not be correctly maintained, leading to inconsistencies.
  
  Solution:
  
  Verify Material Number: Check the material number (&1) to ensure it is correct and exists in the system. You can do this by using transaction codes like MM03 (Display Material) to view the material details.
  Check Construction Type: Review the construction type associated with the BOM or configuration. Ensure that it aligns with the material number you are using.
  Review BOM Configuration: If you are working with a BOM, ensure that the BOM is correctly configured and that the material number is appropriate for the construction type.
  Correct Master Data: If there are issues with the material master data, you may need to update or correct the data using transaction codes like MM01 (Create Material) or MM02 (Change Material).
  Consult Documentation: Refer to SAP documentation or help files for specific details on the construction types and their associated material types.
  Contact Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM03, CS03 (Display BOM), and CS02 (Change BOM) for managing materials and BOMs.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Training and Documentation: Ensure that users are trained on the correct procedures for entering materials and configuring BOMs to minimize errors.
  
  By following these steps, you should be able to identify the cause of the IS245 error and implement the necessary solutions to resolve it.
