Transaction code for Standard Report

Hello Gurus.

My Requirement is: I have to create a Z-Transaction code(There is no T.code in sap)  for Standard Report-RMMDDIBE .

When I run the Z.Tode, the output is displaying with No tab description(means the output is having tabs.). But with the normal report execution  it is showing the Tabs with its  descriptions.

Can You please give some idea how to resolve this issue whether it is in program level or T.CODE creation level problem?

Here is the screen shots for both cases:

with the Z-Tcode:

Thanks in advance,
