Hi I am new to ER and keep running into problems
I need to change the layout and add some fields of our Free Text Invoice report. I started using the Microsoft Standard Invoice Model Mapping downloaded from LCS, and got the initial new layout to work.
However I have additional fields which were not available. I added these to the new derived model and that was also working fine. But after I created a new derived model mapping, I did not see the fields that were added in the new Invoice model. and when I tried change the status of the Model mapping I get a whole list of errors, before I have even changed anything to the new model mapping.
Below are some of the errors that I get when trying to change the status of the model mapping
I then tried to change the name of the definition, it allows it when I change the Invoice Project but when I try to change the InvoiceCustomer name I get an error "Cannot find parm method parmExpressionAsString" and I can not save.
Has anyone experienced this problem. Any advice will greatly be appreciated.
Kind regards

Hi Sophia,
To start with, the errors about the check for empty list is usually something you can ignore since typically you will have invoices in the list when you run the report.
This almost looks like the model mapping configuration is pointing to the wrong data model. When you derived the model mapping, did you make sure to set the Target as the derived data model?
