Modify field display at runtime in web dynpro

Former Member — Mon, 18 Jan 2010 10:14:12 GMT

Hi,

I need to change the read-only property of a field at runtime in webdynpro. The read only field should be enabled at runtime.

I've used the call method lo_nd_packslip->set_attribute_property

exporting

attribute_name = 'ZOPAK'

property = '3'

value = space .

but I am not getting the desired output.

Thanks,

where are you calling this event?

same view with some button action command??

I am calling the above method in the specific action event after which the field should be changed.

Thanks

Hello Neha,

You could use another attribute of type wdy_boolean and bound it to the read property of the field.

Now you have to change the value of that attribute to 'X' or ' '.

You could follow other apporach also which you mentioned in your question, instead of using space you could mention ' '.

Blank between quotes.

Hi Neha,

if you follow the other approach (Maintaining another attribute), You would apply abstraction concept of OOPS.
