How To Fix SWF_BND_001250 - Use the binding option 'Allow Empty Row to Be Appended'

SAP Error Message - Details

• Message type: E = Error

• Message class: SWF_BND_001 - Messages for workflow binding class

• Message number: 250

• Message text: Use the binding option 'Allow Empty Row to Be Appended'

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

In the binding, you have defined that the operation 'Append to Table'
appends an empty row. This must be explicitly allowed by a corresponding
binding option, otherwise this statement is ineffective and is not
executed at runtime.

What causes this issue?

The explicit use of ABAP initial values is generally not recommended in
binding modeling. You should only append empty rows if you know that the
application in question supports or requires this.

System Response

How to fix this error?

to Table' in the binding row in question. Select the option 'Allow Empty
Row to Be Appended".

• What is the cause and solution for SAP error message SWF_BND_001250 - Use the binding option 'Allow Empty Row to Be Appended' ?

  The SAP error message SWF_BND_001250, which states "Use the binding option 'Allow Empty Row to Be Appended'," typically occurs in the context of SAP workflows or applications that involve data binding, particularly when working with tables or lists in UI5 applications.
  Cause:
  This error arises when the application attempts to append a new row to a table or list, but the binding configuration does not allow for empty rows to be added. This can happen if:
  
  The data model expects certain fields to be filled in, and the application tries to add a new row without providing values for those fields.
  The binding settings for the table or list do not have the option to allow empty rows enabled.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Enable the Binding Option:
  
  In your UI5 application, locate the binding configuration for the table or list where the error occurs.
  Set the binding option to allow empty rows to be appended. This is typically done in the XML view or in the JavaScript code where the binding is defined.
  For example, if you are using XML views, you might set the allowEmptyRow property to true in the table's binding settings.
  
  Example in XML:
  <Table items="{path: '/YourEntitySet', parameters: {allowEmptyRow: true}}">
      ...
  </Table>
  
  
  Check Data Model:
  
  Ensure that the data model allows for the addition of empty rows. If certain fields are mandatory, consider whether they can be optional when adding a new row.
  
  
  
  Handle Empty Rows in Code:
  
  If you are programmatically adding rows, ensure that you handle the creation of new entries correctly. You may need to initialize the new row with default values or handle the case where the row is empty.
  
  
  
  Review Application Logic:
  
  Review the logic in your application to ensure that it correctly handles the addition of new rows, including any validation that may prevent empty rows from being added.
