No LUW exists in the specified queue

Hello,

Kindly request your help to solve this.

I have entry in our CRM outbound queue with status READY & destination as NONE & two LUW within it with status "Transaction recorded", this queue needs to transfer data from CRM to ECC.

I am trying to activate the queue & while activating the queue I try to change the destination from NONE to ECCCLNT100 & then below window pops up & it does nothing.

Thank you,

Shradha
