  The SAP error message CNV_20100355 indicates that there is an issue with a set class being initialized but not properly populated with values during a data conversion process. This error typically arises in the context of data migration or conversion projects, particularly when using SAP's data migration tools.
  Cause:
  
  Set Class Initialization: The error suggests that a set class (which is a collection of values or a grouping of data) is not initialized correctly. This means that the system expected a set of values to be present, but it found that the set class was empty or not defined.
  Missing Data: The specific value indicated by &1 is not being converted because it does not exist in the expected set class. This could be due to missing data in the source system or incorrect mapping during the conversion process.

  Solution:

  Debugging: If you have access to debugging tools, you can trace the execution of the data conversion process to identify where the initialization fails and why the expected values are not being populated.
