Digital technologies, a concept whose appearance is not new. The reasons for this arrival are collective thanks to the application and acceleration of Industry 4.0, the expansion of high-tech tools and, in addition, the current characteristics of the competitive atmosphere, mainly in terms of improbability, difficulty and enduring changeable aspects.

The acceptance of digital technologies in supply chains, referred to by the authors as "Supply Chain Digital", is becoming a necessity for companies to secure their position in this situation, as it improves competitiveness, which translates into availability of goods, reduced expenses and improved field positions.

With this in mind, a number of important questions need to be asked: what are the definitions and evolution of the phenomenon, what are its characteristics and related technologies, and what are the levers and barriers to its adoption? In order to provide some answers to these questions, we have conducted a literature review of scientific works that have analyzed the adoption of supply chain technologies. In this respect, we have tried firstly to build up a corpus of developments in the phenomenon of supply chain digitization, and secondly to list the challenges and difficulties of implementing digital technologies in the supply chain.

The results show, via an analysis of the scientific literature, that the adoption of supply chain digitization is a phenomenon under investigation, which few studies have been able to address from the conceptualization of the digital supply chain, even if the latter also proposes a series of measures to promote the dissemination of information, stimulate responsiveness and collaboration, and even agility. On the other hand, this phenomenon also reveals major levers and obstacles that make the adoption of digital technologies in the Supply Chain more delicate.
