assigned only to an interface parameter field if the associated sender
parameter &V2& in the knowledge base settings (KB) is the respective
extension table.

System Response

You <ZH>cannot </>assign this move parameter to the given interface
parameter field.

How to fix this error?

Change the knowledge base settings (KB) and set the required extension
table as the sender parameter or assign a different move parameter.

• What is the cause and solution for SAP error message CNV_PE602 - Move parameter cannot be assigned for the given sender parameter in KB ?

  The SAP error message "CNV_PE602 Move parameter cannot be assigned for the given sender parameter" typically occurs in the context of data migration or conversion processes, particularly when using the SAP Conversion Tools or during the execution of a program that involves parameter mapping.
  Cause:
  This error usually arises due to one of the following reasons:
  
  
  Data Type Mismatch: The data type of the source parameter does not match the expected data type of the target parameter. For example, trying to assign a string to an integer field.
  
  
  Incompatible Structures: The structures of the source and target parameters may not be compatible. This can happen if the fields in the structures do not align correctly.
  
  
  Missing Parameters: The sender parameter may not be defined correctly or may be missing in the context where it is being referenced.
  
  
  Incorrect Mapping: The mapping of parameters in the conversion program may be incorrect, leading to an attempt to assign values inappropriately.
  
  
  Solution:
  To resolve the CNV_PE602 error, you can take the following steps:
  
  
  Check Data Types: Verify that the data types of the sender and receiver parameters are compatible. Ensure that you are not trying to assign a value of one type to a parameter of another incompatible type.
  
  
  Review Parameter Mapping: Go through the mapping of parameters in your conversion program. Ensure that all parameters are correctly defined and that their structures align.
  
  
  Debugging: If you have access to debugging tools, you can set breakpoints in the program to inspect the values and types of the parameters at runtime. This can help identify where the mismatch occurs.
  
  
  Consult Documentation: Refer to the SAP documentation or notes related to the specific conversion tool or program you are using. There may be specific guidelines or known issues that can provide further insight.
