Hi Luis,

I also had the same problem.

You might have something wrong with your UDFs.

Unfortunatelly your mapping is lost.

Re do it again and please check that your UDFs are correct. And if you don't find anything try removing any reference to the UDFs, save and activate.

That might let you open the mapping again.

Later you can use your UDFs one by one to check which one is giving you that problem.

Hope that helps.

Hi Luismier

Thanks for your answer. yeah I tried againg and I deleted the reference , so I guess the problem is with UDF function.

Hi,

Goto history in mapping and just roll back previous version. Tyr to save/activate it and then look for new changes.

Thanks

check whether your source data type or target data type are changed or

diffrent data types might have been assaigned to message types that can also be the reason to get the maping deleted

Luis,

Please check whether you have the source and target data types exist or not. May be somebody delted them.
