Issue
An existing Business Layer that is consumed by a Data Source definition in Design Studio 1.2 Version: 12.0.2.201311041742 seems to invalidate the entire Data Source object after modification to the base tables DDL (data definition). Information Design Tool used is Information Design Tool 4.1, Build:14.1.1.1036, Version: 4.1 Support Pack 1.
Background
A modification was needed a base tables DDL (data definition). Specifically a column that stores the Date value as a varchar needed to update to a Date data type. After the modification was completed the Data Foundation and Business Layer in the Information Design Tool (IDT) needed
modification as well to reflect the updated column data type. Refreshing the Data Foundation and/or the Business Layer did not update the column Data Type. The step of dropping and re-inserting the updated table in the Data Foundation and subsequently the Business Layer updated
the expected columns Data Type as expected. All the existing Data Source definitions that were in use throughout the application (Design Studio) were invalidated causing the following error after the DDL update.
After rebuilding the Data Source definition in Design Studio, the issue was no longer there however, the existing Data Sources were still non-functional and were subsequently deleted.
In Sum
Is there another way to make changes to the base table(s) without negatively impacting the Data Foundation (IDT)àBusiness Layer (IDT)àData Source Definition (Design Studio) to the point where Data Sources on the Design Studio have to be redone preceded with similar effort at the IDT level? Is there a step(s) that I missed?
Any insight would be appriciated.
