Hi Leon,
The order is arbitrary but all of the implementations will be called.. there is no way to figure out the sequence.. here is what SAP has to say..
"Multiple use for BADI definitions means that there can be several active BADI implementations. When there is a call, they are all called up - however, in an unpredictable sequence. If you have multiple-use BADI definitions, the sequence must not play any role therefore. "
