The SAP error message CNV_PE_IF_RT036 typically occurs during data migration or conversion processes, particularly when using the SAP Landscape Transformation (SLT) or other data migration tools. This error indicates that a fixed value is being incorrectly assigned to a field that does not accept it, often due to data type mismatches or incorrect field mappings.
Cause: Field Type Mismatch: The fixed value being assigned does not match the expected data type of the target field. For example, trying to assign a string to a numeric field. Incorrect Mapping: The mapping configuration in the data migration tool may be incorrect, leading to an attempt to assign a fixed value to a field that is not designed to accept it. Field Attributes: The target field may have specific attributes (like being a key field or having certain constraints) that prevent it from accepting fixed values.
Solution: Check Field Mappings: Review the mapping configuration in your data migration tool.
