Effect of Replication of DataSource on Delta mechanism

Hi All,

Datasource 0UC_SALES_STATS has one custom field and we would like to change the description of that field.

This will change the append structure and so extract structure.

To get this description in BW, we need to replicate the Datasource.

Now since this datasource is productive in production system and bringing delta, want to what will be effect on delta load?

Will need to perform init again? or we can run delta as normal?

Any help will be appreciated.

Thanks,

Swati
