C4C Sales Order Approval

Hi,

I have one C4C Sales Order which get replicated from ECC to C4C and then this order need to be reviewed by sales rep through Ipad, and the last might do some changes by adding more products or change the quantity.

the issue now that these changes are getting updated into ECC directly without asking for approval process, while already i have the approval process in place which is working fine for order that are created through C4C directly.

Thanks

Ahmad
