Material Numbers-IDocs

Hi All

When I created material number say 123 , that is being stored in tables as 0000000000000123.

In OMSL T code Lexcographical indicator is not set.

When I receive Inbound Del Order, Idocs errors I am facing.

Now I need material 123 to be stored as 123 only .i.e. i need to create material number as 123 only without leading zeros.

I cannot be able to set Lexcographical indicator In OMSL T code as already numerical numbers exist in system.

How I can resolve this.

Please help me.

Best Regards

Rahul
