Revenue from Contract with Customer [Abstract]
Remaining Performance Obligation [Text Block]	Remaining Performance Obligations (RPO)RPO represent the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. Total RPO was $156.1 billion and $150.1 billion as of September 30, 2021 and December 31, 2020, respectively. Of the total RPO as of September 30, 2021, we expect approximately 30% will be recognized as sales over the next 12 months. This percentage of RPO to be recognized as sales over the next 12 months depends on future developments, which are highly uncertain and cannot be predicted, including new information which may continue to emerge concerning the scope, severity and duration of the COVID-19 pandemic, as well as any worsening of the pandemic, the effect of additional variants, the efficacy, acceptance, distribution and availability of vaccines, new or continued actions to contain the pandemic’s spread or treat its impact, and governmental, business and individual personal actions taken in response to the pandemic, which may result in customer delays or order cancellations.
