Unable to save a Z-Tcode in Custom Package,unable to assign a transport Req

Question

Hi all,
I am trying to create a T-code for standard SAP Program RSTXPDFT4. I was able to successfully create a T-code for this report program which has selection screen.
But I created it as a Local Object.
Now I am trying to create another T-code for the same SAP standard program in our custom package used in our company called /ABCDE/FGH01.
But it does not allow me to save the T-code in this custom package and throws an error saying
u201CCustomer Object Z_TCODE cannot be assigned to package /ABCDE/FGH01 u201D.
Why am I unable to save it in a custom package and assign a transport request for it, Is it because I am creating t-code for standard SAP program? If I try to save it as local object I donu2019t get any error and it works perfect. But my actual requirement is to make the object transportable and save in custom package.
Some one please help me with this.

/ABCDE/FGH01 <<< "not a custom package.. custom packages start with Z
/ABCDE/ is a registered namespace, and could very well be customer code. It is not all Y and Z any more.
One thing we noticed when we used a registered namespace was that if your package was in the registered namespace, then your object also had to be. That is, if your tcode starts with Z, your package name must also start with Z. if your package name starts with /ABCDE, the so too must your TCODE. I dont know this to be 100% fact, becuase we no longer use a registered namepsace, i just seem to recall that it was true.
be wary of creating tcodes that start with /, too... the users will always have to put /n or /o in front of them. In general, we really hated using the registered namepsace, and quickly renamed a TON of stuff to get away from it.
