Error while Coping an Module pool program

Hi all,

I had copied an SAP Standard Module Pool Program(SAPMFDTA) into an Z program(ZSAPMFDTA)

Transaction code of the SAP Standard Program is FDTA

I had also Created an Z Transaction code(ZFDTA) for that copied Z Program (ZSAPMFDTA)

I had activated all the Includes,Program,Screen painter

IF i run the Transaction code of the SAP Standard program (FDTA) it is executing Perfectly with out any errors

But if i executed my Z Transaction code(ZFDTA) the error it is showing is Status FDTA100 of the user interface ZSAPMFDTA missing

Please give me the solution for this .

Thanks & Regards
