We are currently using the Java WDP version of the ESS Leave Request and plan to migrate to ABAP WDP version. However, we check that there are more than 200 OSS notes fixes for the ABAP WDP version. Also new fixes are kept on creating in April and May.
What is the reason for such a large volume of fixes? Is the ABAP WDP version of Leave Request mature ? Our management has concern on the risk for the migration.
Please share your experience and advice.
