During each build, BuildPlus creates a Significant Change Report in the project file, which lists all of the exception report blocks in your system that are used as tags or imported into other PCUs. It shows their significant change value in units and percent change. In the case of imported blocks, it links to where the block is used.
The built-in links to the import blocks are very useful. They allow you to cross-check what significant change is being transferred for the purposes of control and tabulation. A mismatch among inputs in another module can cause grief.
The links for all tags allow you to see how the tag is used to see if the significant change setting is appropriate. Both too small and too big can be problems for your operators in their understanding and operation of the process.
This report is always built into the project file and can be seen in Hyperview under the System Information chapter in the Table of Contents in Hyperview.
