update data element in persistent class

Former Member — Thu, 23 May 2013 09:16:31 GMT

Hi there,

I have a DDIC-table, of which I generated a persistent class.

Now I have to change a data type/ data element of a table field. If I go to the persistent class, the data type is still the "old" one.

Is it possible to update the attributes of the class on the basis of the renewed table - or I have to delete this attribute out of the class and add it again afterward!?

Thanks,

Andreas

Hi,

Did you try regenerating/re-activating the class after the change?

Hope this helps,

Yes, I tried reactivating. And a function like "regeneration" I couldn't find in the persistence peresentation mode..

Hello Andreas,

You just need to delete the field from the OR (persistence mapping) and then add the field back. This should do it for you.

And a function like "regeneration" I couldn't find in the persistence peresentation mode

There is no such option for the OR mapping. You have to do it manually.

BR,
