Posted on by 45

Hi,

I am using Data Migration tool : AX 2009 while click on generate mapping I am getting the error "The given value of type string from datasource cannot be converted to type nvarchar of specific target column".

Any suggestions.

Regards,

Kalai

    Hi Kalai,

    Can you tell on what table/field you get this error? Is it a standard or custom one? As you used too many tags in your post, I'm not able to guess in what area you have your issue. Can you also review the tags and only keep the relevant ones?

    Hi Kalai,

    You have to run the powershell command before you start the imports. This updates the model store schema to accept new models.

    Hi Kalai,

    The issue of String error should be gone after increasing the length of DMTName EDT.

    Please also be noted that the 2009 to D365 tool is still in private preview, you can find this issue on to the Yammer group page -  https://www.yammer.com/dynamicsaxfeedbackprograms/#/threads/inGroup?type=in_group&feedId=11106952

    Here are some document for the DMT tool.

    Hi Kalai,

    please help to have a check from stackoverflow, this means you haven't install Microsoft Access Database Engine.

    Could you please create a new thread for the new issues, and please mark this as answered if the suggestion works for you.

    Hello,

    I'm getting the same error by DMT trying to generate maps, the action you suggested should be performed on D365 side or on AX2009 ?

    regards
