• What is the cause and solution for SAP error message DDLS_HIER055 - Load parameter is specified as &1, but needs to be either char or sstr ?

  The SAP error message DDLS_HIER055 indicates that there is an issue with the load parameter specified in a Data Dictionary object, particularly in the context of hierarchical data structures. The error message states that the load parameter is defined as &1, but it needs to be either a character type (char) or a string type (sstr).
  Cause:
  This error typically arises when:
  
  The load parameter in a hierarchical structure (like a hierarchy or a tree) is defined with an incompatible data type.
  The parameter is expected to be a character or string type, but it has been defined as a different type (e.g., numeric or a complex type).
  There may be a mismatch in the data type definitions in the underlying data model or in the configuration of the hierarchy.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Data Type:
  
  Go to the Data Dictionary (transaction SE11) and check the definition of the load parameter that is causing the error.
  Ensure that the data type of the load parameter is either CHAR (character) or SSTR (string).
  
  
  
  Modify the Parameter:
  
  If the data type is incorrect, modify the parameter to use a compatible type (CHAR or SSTR).
  Save and activate the changes.
  
  
  
  Review Hierarchical Structure:
  
  If the load parameter is part of a hierarchical structure, review the entire structure to ensure that all parameters are correctly defined and compatible.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no dependencies or references that might be affected by changing the data type. If there are, you may need to adjust those as well.
  
  
  
  Test the Changes:
  
  After making the necessary changes, test the functionality to ensure that the error is resolved and that the hierarchical data loads correctly.
