If the partner type changes from LS to US.What changes are required?

HI Experts,

The Partner type in WE20 needs to be change from type 'LS' to 'US'.

What changes needs to be done in configuration settings ?

What table entries need to be maintained?

I have currently set up the changes by myself .

The idocs are still in status 29.

Error is 'Entry in outbound table not found'

What am i missing?

Thanks

Balwant
