How to fix this error?

Check the levels assigned to the current hierarchy and, if necessary,

GK226 - Details

• The SAP error message GK226, "You cannot insert below the lowest hierarchy level," typically occurs in the context of SAP's controlling (CO) module, particularly when dealing with hierarchical structures such as cost centers, profit centers, or internal orders. This error indicates that you are trying to insert a node or an element into a hierarchy at a level that is not allowed, usually because it is below the defined lowest level of the hierarchy.
  
  Cause:
  
  Hierarchy Structure: The hierarchy you are trying to modify has a defined lowest level, and the system does not allow you to add elements below this level.
  Incorrect Node Selection: You may be trying to insert a new node or element into a parent node that does not allow further subdivisions.
  
  Configuration Issues: There may be configuration settings in the hierarchy that restrict the addition of new nodes.
  
  
  Solution:
  
  Check Hierarchy Levels: Review the hierarchy structure to understand the defined levels.
