  The SAP error message MW351 indicates that there is an issue with the key fields for a material in a specific plant. This error typically arises when the system cannot find the necessary data for the material in the specified plant, which can occur due to various reasons. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Missing Master Data: The material master data for the specified plant is not maintained. This could mean that the material has not been created for that particular plant.

  Data Inconsistency: There may be inconsistencies in the data, such as missing or incorrect entries in the relevant tables.
