Sage evolution with branch accounting in flowgear

Question

I have one question regarding to flowgear with sage evolution(branching) integration. I have created flowgear workflow for client and stkitem data sync with branch accounting(specific Branch id) to my web porter. when i submit order from web to flowgear using specific client and stkitem data at that time sage evolution node giving the error

Record (Customer: THR001C) cannot be used in this context as it is linked to branch 'CH'. Current branch is 'Global'.

My sage evolution node source XML is:
