Recently, I had to move an IDoc between two SAP systems for testing purposes, without the systems being connected in a network. This meant that we had to find a way to export and import the IDoc manually.

The plan involved transferring the IDoc from system A to a file and then importing it into system B from the file. Initially, it appeared to be simple, but it eventually proved to be complicated. Despite minimal guidance from online sources and SAP documents, I was able to figure it out and successfully complete the task. As a result, I would like to provide a detailed guide on how to accomplish this process.

It is important to understand that this is solely meant for the testing of individual cases using manual methods and should not be utilized as an IDoc interface.

Initially, we transfer an already existing IDoc from the source system, save the document on the nearby computer, and then transfer it to a different system.
