  The SAP error message HRPAO_DY_CUST045 indicates that there is an issue with a method definition in an ABAP class or interface. Specifically, the error states that the method must only have importing and returning parameters, which means that the method is incorrectly defined with parameters that are not allowed.
  Cause:
  The error typically arises when:
  
  The method is defined with parameters that are not allowed, such as changing parameters or exporting parameters.
  The method is expected to follow a specific signature as per the SAP standard, which only allows importing and returning parameters.
  
  Solution:
  To resolve this error, you need to modify the method definition in the ABAP class or interface. Here are the steps to do so:
  
  
  Access the ABAP Workbench (SE80 or SE24):
  
  Go to transaction SE80 or SE24 to access the relevant class or interface.

  For example, if you have a parameter defined as changing, change it to importing if it is meant to be an input parameter.
  
  
  
  Activate the Changes:
  
  After making the necessary changes, activate the class or interface to apply the modifications.
  
  
  
  Test the Method:
