Every business is different, many of the business processes might be unique to each customer, which cannot be addressed by SAP standards. So custom developments in an SAP environment are quite inevitable. It's part of any type of SAP project, whether its Implementation, Upgrades, Migrations or Support projects. Even though the best practice is to minimize the number of custom developments and adapt to the SAP standards, practically most of the customers end up in having a substantial amount of custom developments in their SAP environment. Maintaining the custom developments becomes a challenge when it comes to any upgrades and migration projects.
