For different purposes, it may be necessary to compare the contents of tables/views in different SAP systems.
You can upload the data and use the VLOOKUP in MS Excel, or use transaction SCMP, which by then may also run in the background.
The settings are quite simple. On the main screen you choose a table / view to compare and select the desired connection to the SAP system, with which the comparison is performed.
Advanced settings allow to look at only the differences in tables, and perform a comparison in the background.
