Hi Rahul,
You can attach your search help to the data element in the SE11. Then it will atomatically appear when you press F4 for  that field.
dont try to use match code syntax, because match codes are obsolate in latest versions.
for your reference:
Attachment of Search help:
Attach a search help to a structure or table field: The attached search help is available for all screen fields that refer to the table or structure field. There must be an assignment between the interface parameters of the search help and the fields of the table or structure for this type of attachment. In the input help process, this assignment results in a value transport between the corresponding fields (if they are known at least to the module pool of the screen) and the search help parameters. As for the foreign key definition, you can assign nothing, a constant or any other field (which is then sought in the module pool) to indivdiual search help parameters.
2. Attach a search help to a table: The assigned search help is available for all screen fields for which the table is a check table. There must also be an assignment between the search help parameters and the key fields of the table for this type of assignment.
3. Attach a search help to a data element: The attached search help is available for all screen fields that refer to the data element. If the search help is attached to a data element, an export parameter of the search help must be assigned to the data element. If the user chooses a row of the hit list in the input help, the contents of this parameter are returned in the corresponding screen field. More than one value is not returned when a search help is attached to a data element.
