Dynamic Search help assignment

[Former Member]

Like in R/3 screens, we can assign a field which will determine the input help to use, can we have a similar functionality in Web Dynpro abap?

THanks in adv.

Hi Swetha,

Yes we have , if data element has the search help and if you give the type of attribute is the data element which have serch help.Automatically your input field will have serach help.

Eg:

Take one input field in the layout and bind that with context attribute carrid of type scarrid then activate and execute.you will find the serach help for carrdid field.

I think my question was not very clear.

I know the input help comes automatically based on the Data element.

What i was asking is that like in R/3 Dialog screens, we can assign a parameter to the search help. That parameter value we can change in the program and the corresponding input help would be then called.

Can we have a similar thing in Webdynpro? I want to have a parameter which will be populated at runtime with the name of the search help to be called?

Actually my problem is, when user presses F4 on one input field, i want to do some validations whether another field is populated or not. If it is not populated, I dont want to show F4 help, and want to give error in that case.

But if the value of the other field is populated correctly, then I want to show F4 with the correct values.

Thanks.
