I want to change the SearchHelp for a standard SAP field 'PMActType' (CAUFVD-ILART) on screen SAPLCOIH.E3000 (part ot transaction IW31).
Based on the help documentation it seems like I should be able to use the follwing:
SearchHelp F[PMActType] techname"CAUFVD- ILART" shname=Z_GENORDTYPE
(where Z_GENORDTYPE is my new custom searchhelp).
However I still get the standard searchhelp when hitting F4.
Is my syntax wrong, or do I also have to install program ZGUIXTF4 even though this is a standard SAP field? Or maybe I misunderstood and I cannot redirect the SearchHelp on a standard SAP field.
