• What is the cause and solution for SAP error message SOI820 - Table &1 field &2 attribute &3 changes are not supported ?

  The SAP error message SOI820 indicates that there is an attempt to change a field attribute in a table that does not support such changes. This typically occurs in the context of SAP's data dictionary and can be related to various scenarios, such as trying to modify a field in a database table that is either locked, not allowed to be changed, or is part of a structure that has restrictions.
  Cause:
  
  Field Attribute Restrictions: The field you are trying to modify may have restrictions based on its data type, or it may be part of a structure that does not allow changes.
  Database Locking: The table or field may be locked due to ongoing transactions or other processes that are preventing changes.
  Custom Development: If the table or field is part of a custom development, there may be specific rules or constraints that prevent changes.
  Transport Issues: If you are trying to transport changes from one system to another, there may be inconsistencies or issues with the transport request.
  
  Solution:
  
  Check Field Attributes: Review the field attributes in the Data Dictionary (SE11) to ensure that the changes you are trying to make are allowed. If the field is part of a structure or a table that has restrictions, you may need to reconsider your approach.
  Unlock the Table: If the table is locked, you may need to wait for the current transaction to complete or manually unlock it if you have the necessary permissions.
  Review Custom Code: If the field is part of a custom development, check the associated code or configuration to ensure that it allows for the changes you are attempting.
  Consult Documentation: Refer to SAP documentation or notes related to the specific table and field to understand any limitations or requirements for making changes.
