All,
We have developed a few SSIS packages using SSIS-2012 to load data into an OLTP system. This is basically a migration project. The problem over here is that, new fields are being added into OLTP system very frequently. So our ETL's are failing due to metadata issues: -
"TASK NAME" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
This is quite obvious because the target's metadata is changed. Right now we are manually open each and every package and sync up (Open the destination, click on mappings and click OK on the mapping screen) the changes.
There are quite a few packages and its become an hectic task to manualy syncup these changes.
Is there any automated way to sync up the ETL's with metadata? Or is there any option in SSIS to choose only selected columns in target and map it to source?
For instance - lets say when we were developing the package, there were 10 fields and we have mapped these 10 fields. The ETL is working fine. Later two more new fields are added to target, now our ETL's will fail stating metadata issues. Until we open the package and sync with DB, this error wont be gone. Can we make the sync up automated so that the new fields are mapped to <ignore>?
Thanks.
