IDOC: message type CLFMAS

Is there a program that will distribute material class data via message type CLFMAS for specific materials.

Program RBDSECLF will distribute this information, but the selection screen does not include material, so it will send IDOC for all materials.

This problem occurs because I am pre-loading material master from different instances using LSMW and want to load material class data after.

Program RBDSECLF (BD93) allows the selection of change number.

Could I assign a change number to the materials for which I want to distribute CLFMAS?

Need to read up on change numbers.
