How to fix this error?

The specified field dependency is probably for navigation, so the type '
' must be entered in this case.
The following values are valid field relationship types:
' ' : (foreign) key dependency (normal case). The relationship is used
in the navigation and when determining dependent entries.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

'S': the object field is read only. The value for this field is defined
in the predecessor object, and is only displayed in the current object.
The field is flagged in the data dictionary as a subset field, but it is
not a key field, it is a text field which contains an explanation of a
key field which is defined as a subset.
The field is flagged in the data dictionary as read-only.
If case 2 applies, you must flag the field in the data dictionary as a
subset field or a read-only field.

• What is the cause and solution for SAP error message SV578 - Field & of object & is not read only. ?

  The SAP error message SV578 indicates that a field in a specific object is not set as read-only, which can lead to issues when trying to perform certain operations that expect the field to be immutable. This error typically arises in the context of data entry or modification in SAP applications, particularly when dealing with screen fields or data objects.
  Cause:
  
  Field Configuration: The field in question is not configured as read-only in the screen or data dictionary. This can happen if the field is intended to be editable but is being treated as read-only due to the context of the operation.
  Authorization Issues: The user may not have the necessary authorizations to modify the field, leading to the system treating it as read-only.
  Program Logic: The program logic may incorrectly assume that the field should be read-only based on certain conditions that are not met.
  
  Solution:
  
  
  Check Field Properties: 
  
  Go to the Data Dictionary (SE11) and check the properties of the field in question. Ensure that it is set to the correct attributes (editable or read-only) based on your requirements.
  
  
  
  Screen Configuration:
  
  If the field is part of a screen (transaction), check the screen layout in the Screen Painter (SE80) or the relevant transaction. Ensure that the field is not set to read-only in the screen attributes.
  
  
  
  Authorization Check:
  
  Verify that the user has the necessary authorizations to modify the field. This can be done by checking the user roles and authorizations in transaction PFCG.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the program to see the logic that leads to the field being treated as read-only. Look for any conditions that might be affecting the field's status.
