Search Help Exit: shlp_tab-selopt not filled

Hello Experts,

I'm currently creating a F4-help for the material master.

Everything works fine as long as I have set "Dialog (modal)" in my personal preferences.

Table shlp-tab-selopt is filled for the name of my searchhelp with the selection-criteria I entered:

1 ZMATQ MATNR_IN I EQ 000000000000285041 
2 ZMATQ WERKS_IN I EQ 0005 

Everything fine so far - but after switching my preferences to "Control (amodal)", the selection-criteria are not in the selopt-table any more?!

I am using the "SELECT"-event in the searchhelp exit - and I have no idea what the reason for this strange behavior could be?!

Do you have any experiences with this issue?

Kind regards,

Mathias Baumhoff
