standard text: client dependent? how can we move to different client.

I have created a standard text in SO10.

i am using it in my smart form.

my development client is 010.

testing client is 020.

when i test in 020, i am getting error that standard text is not available.

So I think, standard may be either client dependent or we may have different mechanism to move the standard text like LSMW.

Please let me know the process.
