• What is the cause and solution for SAP error message MPN01057 - Combined length of Ext Mfr, Mfr Part No, and delimiter must not exceed &1 ?

  The SAP error message MPN01057 indicates that the combined length of the external manufacturer (Ext Mfr), manufacturer part number (Mfr Part No), and the delimiter used between them exceeds the maximum allowed length defined in the system. This error typically occurs when you are trying to create or update a material master record or a related document that includes these fields.
  Cause:
  The error is caused by the total character count of the following components exceeding the defined limit:
  
  External Manufacturer (Ext Mfr)
  Manufacturer Part Number (Mfr Part No)
  Delimiter (usually a character like a hyphen or slash used to separate the two fields)
  
  For example, if the maximum allowed length is 30 characters, and you have:
  
  Ext Mfr: 15 characters
  Mfr Part No: 16 characters
  Delimiter: 1 character
  
  The total would be 15 + 16 + 1 = 32 characters, which exceeds the limit.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Lengths: Review the lengths of the Ext Mfr and Mfr Part No fields. Ensure that their combined length, including the delimiter, does not exceed the maximum allowed length.
  
  
  Shorten the Values: If the combined length exceeds the limit, consider shortening either the Ext Mfr or Mfr Part No. This may involve using abbreviations or a different naming convention.
  
  
  Change the Delimiter: If applicable, consider using a shorter delimiter or removing it altogether if it is not necessary for your use case.
  
  
  Consult Documentation: Check the SAP documentation or configuration settings to confirm the maximum length allowed for these fields. This can vary based on system settings or customizations.
  
  
  Test Changes: After making adjustments, try to save or update the record again to see if the error persists.
