How To Fix FDT_CORE901 - &1 is unnamed and is used by more than one object

SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_CORE - Formula & Derivation Tool: Core

• Message number: 901

• Message text: &1 is unnamed and is used by more than one object

What causes this issue?

The unnamed object with ID &v1& is used by at least two objects.
However, unnamed objects should be used by exactly one object only. This
is because unnamed objects are closely bound to the using objects and
can normally not be reused by other objects. Unnamed objects with more
than one usage therefore indicate a potential database problem.

System Response

How to fix this error?

You may solve this problem in different ways, depending on the
complexity of the superordinate objects using the unnamed object:
a) Low complexity:
Rebuild the superordinate objects and replace the original superordinate
objects by the new ones.
In the BRFplus workbench, choose Tools -> Application Administration and
run the 'Cleanup unnamed unused objects' command for the application in
question.
b) High complexity:
RESET N1
Check which objects are using the unnamed object.
For each usage that you find, check whether the affected objects are
needed for a valid use case. If not, delete the respective objects.
Retest your scenario and check if everything is OK now.
If there are still problems remaining, get in contact with SAP.

• What is the cause and solution for SAP error message FDT_CORE901 - &1 is unnamed and is used by more than one object ?

  The SAP error message FDT_CORE901 indicates that there is a naming conflict in the context of the Form Data Tool (FDT) or the Adobe Forms. Specifically, the error message states that an object (like a field or a data element) is unnamed and is being used by more than one object, which can lead to confusion and conflicts in the form processing.
  Cause:
  
  
  Unnamed Objects: The error typically arises when there are objects (fields, data elements, etc.) in the form that do not have unique names. This can happen if:
  
  You have multiple fields or elements that are created without specifying a unique name.
  There are duplicate references to the same unnamed object across different parts of the form.
  
  
  
  Form Design Issues: The issue may also stem from the way the form was designed or modified, where changes were made without ensuring that all objects have unique identifiers.
  
  
  Solution:
  To resolve the FDT_CORE901 error, you can follow these steps:
  
  
  Identify the Conflicting Objects:
  
  Open the form in the Form Builder or the relevant design tool.
  Look for any unnamed objects or fields that are being used multiple times.
  
  
  
  Assign Unique Names:
  
  For each unnamed object, assign a unique name. Ensure that no two objects share the same name.
  Check the properties of each object to confirm that they are correctly named.
  
  
  
  Review Object References:
  
  Ensure that all references to the objects in the form are updated to reflect the new unique names.
  If you have scripts or logic that reference these objects, make sure to update those as well.
  
  
  
  Test the Form:
  
  After making the changes, save the form and test it to ensure that the error no longer appears and that the form functions as expected.
  
  
  
  Documentation:
  
  Document the changes made to the form for future reference and to help prevent similar issues.
