In IDQ 9.1 when we import a relational data obejct to workspace to create mapping on it, in the General properties of the same there is one option thats read as:
When Column metadata changes:
option 1: Synchronize output ports
option 2: Do not synchronize
How exactly this option effects the data and mapping process?
Thanks & Regards,
If you alter/drop any columns in IDQ table then do Synchronize output ports this will ask for changes to retains or overwrite from different external resource(Database), It means this changes will be done in databade level too.
