• What is the cause and solution for SAP error message USMD_CONV_SOM_GOV021 - &1 belongs to a range; the assignment &2 (parent &3) cannot be changed ?

  The SAP error message USMD_CONV_SOM_GOV021 typically occurs in the context of SAP Master Data Governance (MDG) when there is an attempt to change a value that is part of a defined range or set of values. This error indicates that the specific assignment you are trying to modify is not allowed because it is linked to a range of values that cannot be altered.
  Cause:
  
  Range Assignment: The error suggests that the value you are trying to change (denoted as &1) is part of a predefined range. In SAP MDG, certain values are grouped into ranges for validation and consistency purposes.
  Parent-Child Relationship: The error message also indicates that the assignment (&2) is related to a parent (&3). This means that the value you are trying to change is dependent on a hierarchical structure, and changing it could violate the integrity of that structure.
  
  Solution:
  
  Check the Range Definition: Review the configuration of the range to understand why the value cannot be changed. You may need to consult with your SAP configuration team to see if the range can be modified or if a new range needs to be created.
  Review Parent-Child Relationships: Investigate the parent-child relationships in your data model. Ensure that any changes you want to make do not violate the existing relationships. If necessary, you may need to adjust the parent assignment before changing the child value.
  Data Governance Policies: Ensure that your changes comply with the data governance policies in place. Sometimes, certain values are locked down to maintain data integrity.
  Consult Documentation: Refer to SAP documentation or help resources for more specific guidance on handling this error in your version of SAP MDG.
