Search help in read only field in ALV

Hello,

I have an ALV. I try to add a search help for one of the fields (read only field).

I set in the context the attribute 'Input Help Mode' to 'Dictionary Search Help' and set the name of the search help in attribute 'Dictionary Search Help'. The problem is that it is only works to when I set the field to be editable. When the field is read only, what I need, the search help not shown.

It is possible to set search help for read only field?

Best regards,

Ednri.
