calling a standard search help explicitly

Former Member — Wed, 05 Mar 2008 09:09:28 GMT

I want to call a standard search help explicitly, instead of attaching it at field catalogue level incase of an ALV grid.

Please answer .. It's urgent.

You can attach the standard search help in the data element level in your data dictionary level.....if the search help is attached in the data elemnt level then on your alv grid the search help comes automatically.

use ref_table and ref_field in your field catalogue attributes.

or you can do this....

please refer to the following code.....
