• What is the cause and solution for SAP error message /SMB/CONT_RESTRUCT077 - Only conversion of NUMC is supported ?

  The SAP error message /SMB/CONT_RESTRUCT077: Only conversion of NUMC is supported typically occurs in the context of data conversion or restructuring processes, particularly when dealing with data types in SAP systems. This error indicates that there is an attempt to convert a data type that is not supported by the system, specifically when trying to convert a field that is not of type NUMC (numeric character).
  Cause:
  
  Data Type Mismatch: The error usually arises when there is an attempt to convert a field that is not of type NUMC into a NUMC type. This can happen during data migration, transformation, or when using certain functions that expect a specific data type.
  Incorrect Mapping: If you are using a data mapping tool or a transformation process, the mapping may incorrectly specify a non-NUMC field to be converted to NUMC.
  Data Integrity Issues: The source data may contain values that cannot be converted to NUMC, such as alphanumeric characters or special symbols.
  
  Solution:
  
  Check Data Types: Review the data types of the fields involved in the conversion. Ensure that only NUMC fields are being converted to NUMC. If you have fields of other types (like CHAR, DATS, etc.), you need to handle them appropriately.
  Adjust Mapping: If you are using a mapping tool or transformation logic, ensure that the mappings are correct and that only NUMC fields are being converted to NUMC.
  Data Cleansing: If the source data contains invalid characters for NUMC fields, you may need to cleanse the data before attempting the conversion. This could involve removing non-numeric characters or ensuring that the data conforms to the expected format.
  Use Appropriate Functions: If you are using ABAP or other programming languages, ensure that you are using the correct functions for conversion. For example, use CONVERT_TO_NUMERIC for converting to NUMC, and ensure that the input is valid.
  
  Related Information:
  
  NUMC Data Type: In SAP, NUMC is a data type that represents numeric characters. It is often used for fields that are expected to contain numeric values but may also include leading zeros (e.g., postal codes).
  Data Migration Tools: If you are using tools like SAP Data Services or LSMW (Legacy System Migration Workbench), ensure that the field mappings and data types are correctly defined.
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional context or solutions for this error. SAP Notes can often provide patches or workarounds for known issues.
