RMDATIND for MM02

Hi all,

I'd like to know if using RMDATIND for a material updating, so simulating MM02, I have to fill into the file all fields or there is a way to fill only that ones I want change, for example, in order to change material description can I pass only BMMH1-MAKTX or do I have to fill all fields in BMMH1?

I tried so but It doesn't work, as SAP performs all checks on obligatory fields I didn't fill into my file...

Thanks GN
