• What is the cause and solution for SAP error message AQ628 - Move exactly one field group ?

  The SAP error message AQ628, "Move exactly one field group," typically occurs in the context of ABAP programming when there is an issue with the way data is being moved between field groups or structures. This error indicates that the ABAP program is attempting to move data in a way that does not conform to the expected structure or field group definitions.
  Cause:
  
  Incorrect Move Statement: The error often arises from an incorrect MOVE statement where the source and target do not match in terms of structure or field group.
  Field Group Definition: The field group may not be defined correctly, or the program may be trying to move data to or from a field group that is not properly initialized or populated.
  Multiple Fields: The move operation is expected to involve exactly one field group, but the code may be attempting to move multiple fields or an incompatible structure.
  
  Solution:
  
  
  Check MOVE Statement: Review the MOVE statement in your ABAP code. Ensure that you are moving data from one field group to another correctly and that the source and target are compatible.
  MOVE <source_field_group> TO <target_field_group>.
  Ensure that <source_field_group> and <target_field_group> are both defined as field groups and that they contain compatible fields.
  
  
  Field Group Initialization: Ensure that the field groups are properly defined and initialized before the move operation. You can define a field group using the FIELD-GROUPS statement.
  FIELD-GROUPS: <field_group_name>.
  
  
  Single Field Group: Make sure that the move operation is only involving one field group at a time. If you need to move multiple fields, consider moving them individually or restructuring your code to comply with the requirement.
  
  
  Debugging: Use the ABAP debugger to step through the code and identify where the error occurs. Check the values and types of the variables involved in the move operation.
  
  
  Consult Documentation: If you are unsure about the structure of the field groups or how to properly use them, refer to the SAP documentation or ABAP programming guidelines.
  
  
  Related Information:
  
  ABAP Documentation: Review the official SAP ABAP documentation for detailed information on field groups and the MOVE statement.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  
  By following these steps, you should be able to identify the cause of the AQ628 error and implement a solution to resolve it.
