  The SAP error message R11284 indicates that there is an ambiguity in the RFC (Remote Function Call) regarding the CONSNUMBER parameter. This typically occurs when the system encounters multiple entries that match the criteria specified by the CONSNUMBER, leading to confusion about which entry to use.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that there are multiple entries in the database that correspond to the same CONSNUMBER. This can happen due to data inconsistencies or incorrect data entry.
  Configuration Issues: There may be issues in the configuration of the RFC destination or the way the function module is set up.
  Data Integrity Issues: If the data in the relevant tables is not properly maintained, it can lead to ambiguities.
  
  Solution:
  
  
  Check for Duplicates: 
  
  Use transaction codes like SE11 or SE16 to check the relevant database table for entries with the same CONSNUMBER. Identify and resolve any duplicates.
  If duplicates are found, determine which entry is correct and remove or correct the others.
  
  
  
  Data Cleanup: 
  
  If the duplicates are due to data entry errors, perform a data cleanup to ensure that each CONSNUMBER is unique.
  
  
  
  Review RFC Configuration:
