Uanable to save edits !

Hi All,

I'm getting message 'Unable to save edits' while trying to save bulk updates in ArcSDE versioned data.

We are using ArcSDE 9.3, Oracle 10g & ArcMAP10

We are able to save up to certain records, say 300, but selected more records say 500, and edit some attributes, then it doesn't
save and comes up with an error message 'Unable to save edits'.

Is anyone had similar issue ? is it a database issue ?

Please help\reply, your assistance is much appreciated

Thanks
Basu
