Hi All.

....

Anyway, the notifications and replacements are correctly updated in the backend.

Any ideas?

Thankyou in advance.

Hi.

After I rechecked the trace I found out, that the XML which is logged regarding the messages seems to be invalid. Unfortunately I don nozt have the trace anymore but there was invalis XML like the following:

<xxx<b>>tus><a>...</</b>a></status></xxx>

I am not sure whether this is just a bug in logging xml or this is the xml as received.

After i resynced no error was given, but some of the data in nearly each syncbo are missing, for example the customer name is missing or some of the connection objects are missing in I02.

Very strange.

Any ideas?

Cheers,

Sascha

Hi again.

Just another suggestion/question. I am not sure which Sync Servlet is installed on the WAS but I guess it is older then SP16. Where can I get the corresponding ear files for Sync Servlet SP16 or SP 17.

Thanks again.

hello sascha,

looking at the messages, you have two delete messages for

the same syncbo processed at the same time... this might

have triggered the error...

Hello Jo.

Thanks for that hint I did not see it by myself

But how should I handle this? It means that the middlewra sne two deletion messaged for the same object, am I rite?

How can this happen?

Best regards,

Sascha

hello sascha,

yeh, it's really weird. try checking your worklist monitor

if the middleware really did sent 2 succeeding delete messages.

might also worth checking on the merep_log for any errors

which lead to this.

Hello Jo.

Seems that we have some error with our SyncBo exists on the middleware. As we switched them off, everything works fine so we have to recheck whats wrong with the exits.

But thank you very much so far. I did not see the duplicated delete messages in the trace.

Cheers,

Sascha

hello sascha,

nice to hear that... first i suspected that it might be a problem with the BAPI but i doubted. anyway, just give us

a feedback on what was wrong with your exits.

Hi Jo.

We are fetching data from 2 backends in these exits. There were some bugs in this area but I can't tell in detail, cause this programming part was not mine.

Anyway thanks for your usefull hint.

I already assigned you some points but I bet this is not very interesting for you, cause you have a lot of

Cheers,

Sascha
