Incorrect calculation of miscellaneous charges

Hi all,

I have now joined dynamicsuser.net and hope that anybody can help me with some development task.

When a new sales order is invoiced, the miscellaneous charges are calculated incorrect. I'd like to know where this calculation takes place, especially the entry of a new data record into the "MarkupTrans" table.

I think this must be either in form "SalesEditLines" or in class "SalesFormLetter". I searched through every method in that form and class, but I cannot find the calculation respectively the entry to "MarkupTrans" table.

I hope anybody can tell me.

Thanks,

Johannes
