SAPMEINT - IDOC problem

Hi

I have a weird problem here (I tried only MATMAS). MII gets the IDoc only after 2 sending. Each time I trigger IDoc in ERP, MII does not get it. MII get it only second time. No error in Log.

I deleted the Idoc in MII (Message Monitor ) and SAPMEINT (Queue Monitor - High Perfomance Integration) and tried it again. And it is always the same problem.....first MATMAS no entry , MII get the MATMAS only after 2nd trigger.

any idea?

I am using SAPMEINT High Perfomance.

p/s: I have another machine with SAPMEINT Standard Integration and using other logical system in ERP. MII in this machine receive all the IDOCs.

Any clue

thanks
