Error by using EEWB

Hi all,

I'm working on CRM5.0 and created a new field with the EEWB in table smovbak. After that I transported the changes and all works fine.I create a second field using the same project and extension and create a new transport order. Now I get an error message 'Request/task XXX cannot be changed because it has already been released.'

I try to get back the old version but I get the same error message.

Have anyone an idea how I can solve that problem?

Thanks in advance

Tobias
