Append Structure in DataSource

Hi Experts,

I added the ZZ* field in the existing append structure of 2LIS_13_VDITM data source. But every time we add any new ZZ field all the other ZZ fields automatically removed from the append structure. we have to add manually again all the ZZ fields in the append structure.

We are facing this problem from the very long time.

Is there any workaround to solve this?

Thanks,

Abhimanyu.
