STEEM withdrawal gone missing

[scheikhzen87]

I did this large withdrawal of 11380 steem coins out of bitshares and into my poloniex account yesterday.  Nothing arrived yet a poloniex.  I'm troubled because I couldn't even locate the transaction on steem block explorer steemd.com
Can someone help me locate the transaction on the blockchain please?
