• What is the cause and solution for SAP error message CNV_CMIS155 - Type change (&3->&4) not allowed between sender field &1 and reciever &2 ?

  The SAP error message CNV_CMIS155 indicates that there is a type change that is not allowed between a sender field and a receiver field during a data migration or conversion process. This typically occurs in the context of using the SAP Conversion Management (CM) tools, particularly when dealing with data mapping between different structures or formats.
  Cause:
  The error arises when there is an attempt to map a field from a source structure (sender) to a target structure (receiver) where the data types are incompatible. For example, you might be trying to map a numeric field to a character field, or a date field to a string field, which is not permissible.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types: Review the data types of both the sender field (&1) and the receiver field (&2). Ensure that they are compatible. You may need to change the data type of one of the fields to match the other.
  
  
  Adjust Mapping: If the fields are indeed incompatible, you may need to adjust your mapping logic. This could involve:
  
  Changing the target field to a compatible type.
  Using a transformation or conversion function to convert the data from one type to another before mapping.
  
  
  
  Review Conversion Rules: If you are using a predefined conversion rule, check if there are any settings or configurations that need to be adjusted to allow for the type change.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific conversion tool you are using. There may be guidelines or best practices for handling type changes.
  
  
  Testing: After making changes, perform a test run of the data migration to ensure that the error is resolved and that data is being mapped correctly.
