      Hi Dinesh,,


      Our project needed an in-depth understanding about SAP Build apps with respect to ODATA POST Call, I have shared this blog with our team. I am sure it will tremendously help the team moving forward.

      Thanks for the blog, keep on adding such informative content. It helps alot of projects in the real time.

      another FACT, any googling with the keywords like ODATA, POST or SAP Build app are only reverting with this blog, so this manifest how rare the general information is available on this topic

      Kudos Mr Dinesh, keep doing the great work
