F4 help in ALV output without using OOP

Hi Experts,

I need to have F4 help for one on the fields on ALV output.

I'm not following OOABAP and I want this to be done only in procedural level.

REF_FIELDNAME and REF_TABNAME in field-catalog definition do not work because the field and table I refer are Z-tables and the fields have no SEARCH HELP defined.

(Some of the blogs gave idea of "F4AVAILABL" property in field-catalog, anyway it threw syntax error)

Please advice me on this.

Thanks in advance.
