Changing the Source Text From the Schema Comparison 
Use
When you use the compare function to compare a schema you have created or changed against another schema, you can use the change function to copy changes from the comparison schema to your displayed schema.
This editor function is particularly useful if you want to compare your customer schema with a standard schema.

Legal changes may trigger changes to a standard schema. The changes to the standard schemas are provided in HR Support Packages. However, if you have changed this standard schema and saved it under a different name, the changes from the standard schema cannot be made automatically in your system. To compare the standard schema with your customer schema and enable you to copy the changes, you can make changes to the source text of your schema from
the comparison function for source text.Prerequisites
Procedure
Result
