SAP Error Message - Details

• Message type: E = Error

• Message class: CRM_BSP_CUSTCHECK - CRM: Blueprint - Consistency Check

• Message number: 201

• Message text: Use an input field instead of a list box

What causes this issue?

You wish to define a dropdown listbox (listbox), the values of which
want to calculate yourself.

System Response

This setting is not possible due to performance reasons:
The allowed values must be calculated again before you save the page,
regardless of whether or not the listbox is executed on the page. The
allowed values are only calculated for input fields with input helps on
request.
Rendering a listbox in the browser is time-consuming.

How to fix this error?

Change the field category to 'input field' and choose 'VALUE_TABLE' as
the application. With these settings, the method
'fill_dropdown_listbox' is called at runtime, with which you can
specify the contents of the input help popup.

Procedure for System Administrators

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