make sure you have been modifing same rec(sales line) in your function UpdateInvDiscAmount();

... Meaning that you probably have 2 different record-variables both changing the same record starting from the same version.

So
R1.GET(); // gets version N of a record
R2.GET(); // gets version N of a record
R1.MODIFY; // writes an updated version N of a record to the DB (that contains version N, so ok), creating version N+1
R2.MODIFY; // ERROR because R2 is version N and in the database is written version N+1

Fix would be:
R1.GET(); // gets version N of a record
R2.GET(); // gets version N of a record
R1.MODIFY; // writes an updated version N of a record to the DB (that contains version N, so ok), creating version N+1
R2.GET(); // gets version N+1 of a record
R2.MODIFY; // all is ok.
