I have created the <searchfield> and assigned it a type and a value. There should be a field in the workarea <wa> with this same type and value.
<searchfield> have a field name. I have created it with CREATE DATA... TYPE... and then assigned a value.
May be I should go through all components of
<wa> and compare their type and value with the type and value of
<searchfield>.
I dont have any other clue.
