Hi All,

Recently, I encountered this synchronization error in AX 2012

Error:

I got this error on opening Customer form after I did a update of my local AX with a copy from UAT AX.

Error:

Illegal data conversion from original field CustTable.ServiceRegionsDN to CustTable.ServiceOrderDN: unable to convert data types to anything but character field type (14 to 49)

Note: ServiceRegionsDN and ServiceOrderDN are custom VAR fields.

Solution:

Note - Please be careful while doing any SQL update from database. I did this in my local sandbox, Not recommended to do it in Production AX.

Check the field id in AOT and compare it with SQLDictionary table in SQL with the following query

select * from sqldictionary where TABLEID in (select TABLEID from sqldictionary where name = 'CustTable')
and name = 'ServiceRegionsDN '

Update SQLDictoniary table with the correct fieldid
update SQLDICTIONARY set fieldid = 60080 where TABLEID in
(select TABLEID from sqldictionary where name = 'CustTable'
)
and name = 'ServiceRegionsDN '
