Creating Material Master data

Hi,

I have to create 10 materials in Dev but these materials are already existing in QA.

Can anyone please let me know what's the fastest way to create these 10 materials?

I did use RMDATGEN program in QA and downloaded one material

and did use RMDATIND program in Dev and uploaded it....

I got a Dump saying "Unable to Interpret 0,00 as a number".

If I have to use LSMW can anyone please let me know what should i define in the Input File and the Source fields and Source Structures?

Thanks in advance!
