Errror -2039 Data Source - Data Was Changed

[#1]

Hi everyone,

We sometime got a error -2039 Data Source - Data Was Changed when we try to post a Incoming payement with SAPbobsCOM.BoObjectTypes.oIncomingPayments.

Do you know what can cause that kind of error. We have around 30 session with a custom sdk devellopppement in c#. A server can hold about 5-6 sessions.

Thanks for the help!
