Hi Lee,
When we choose error stack functionality:
When know that as source may sends wrong data on daily/weekly cases, rather than reloading whole data into target. we use error stack which can hold error records and correct records will update to target.
Check the error stack record and correct them at psa and save it. then trigger the error dtp which can update corrected error stack records to target.
At target level we may see to requests,
one requested loaded thru normal dtp but i will be red, we can make it green once we loaded erroneous records thru error dtp. once you make this as gree, data was available fore reporting.
Another request error dtp which was green.
Please check this:
Thanks
