Item Event - the given key was not present in the dictionary

Dear expert B1,

I have a problem on Incoming Payment.

After I Add new "Document Numbering" for all transaction (sales order, invoice, purchase order, etc) - (eq:start document number became 200900001), and all transaction used the document number that i created.

The problem is when i open incoming payment, the error message appear "Item Event - the given key was not present in the dictionary"

Does the experts have meet same problem with me?

Thank you for your help before.
