Many enterprises are investing tens of millions in modernizing their SAP landscapes, but are often underestimating a crucial factor for success, the training of their own developers, according to the German-Speaking SAP User Group, DSAG. The user association urges CIOs to treat the continuing education of SAP developers not as a voluntary training measure but as a strategic investment program in a new report on upskilling [PDF, in German]. Well-trained developers are essential for building stable, maintainable in-house projects without accumulating technical debt, but without continuing education during the upgrade to S/4HANA, the potential of the new technologies will remain untapped, it warned. As the authors explain, while many ABAP developers have decades of experience with SAP R/3 or ECC and possess extensive process knowledge, development paradigms have fundamentally changed with S/4HANA, Clean Core, and ABAP Cloud.
