Document title ssrs report ax 2012 Parameter does not exist


I am using Dynamics Ax 2012 R2 ( CU7 updated). in SSRS report

When i try to open my customized report SalesInvoice_In I am getting the following error.

Pls Help i have tried to make the parameter as null in contract class

As well as i have set the mandatory values false for parameters in visual studio but doesnt work.

HI Nick ,

Delete the Report from Sql reporting Service and redeploy the report and check.

Thanks for your Reply.

I tried the above steps but i’m still getting that error.

I guess it has something to do with coding. My report contains 5 designs.

All the designs open without error, but as soon as i add charges, i’m unable to view 3 designs as i get the above given error.

Sorry the error is random obtained on any sales order no specific thing to observe.
