• What is the cause and solution for SAP error message WER252 - Field type &1 is mandatory and is not assigned ?

  SAP Error Message:
  
  WER252 Field type &1 is mandatory and is not assigned
  
  Cause:
  This error occurs when a mandatory field type (data element) is required in a particular context (such as a screen, structure, or function module) but has not been assigned or maintained properly. In other words, the system expects a certain field type to be present and linked, but it is missing or not configured.
  Common scenarios include:
  
  Missing assignment of a field type in customizing or configuration.
  A required field type in a data structure or screen is not linked to a domain or data element.
  In HR (Personnel Administration) or Payroll, this can happen if a mandatory wage type or infotype field is not assigned.
  In workflow or data transfer scenarios, a mandatory field type is not mapped or assigned.
  
  
  Solution:
  
  
  Identify the Field Type:
  
  The message will show the field type name in place of &1. Note down this field type.
  
  
  Check Configuration or Customizing:  
  
  Go to the relevant IMG activity or customizing transaction where the field type should be assigned.
  For example, in HR, check the wage type or infotype configuration.
  In data transfer or interface scenarios, check the mapping or assignment of field types.
  
  
  
  Assign or Maintain the Field Type:  
  
  Assign the missing field type to the relevant structure, screen, or customizing node.
  Ensure that the field type is linked to a proper data element or domain.
  If it is a screen field, check the screen layout and field attributes.
  
  
  
  Check Data Element and Domain:  
  
  Use transaction SE11 to check the data element or domain assigned to the field type.
  Make sure it is active and properly defined.
  
  
  
  Transport and Test:  
  
  After making the necessary assignments, transport the changes if required.
  Test the process again to confirm the error is resolved.
