Hi Sander,
Your reply really helped me to found that it is a middleware issue.
But in this case BDOCS are Stuck in SMW01 for BDOC type:BUS_TRANS_MSG since long and in SMQ1 there are Queues with NOSEND status but that are not stuck.
Can you please tell me how data flows from SMW01 to SMQ1?
Also how can i check the data stuck in Intermediate BDOCS in SMW01 which are stuck since long.
Thanks,
Javed
