CUI Number
Definition
In Chile and Peru, you are required to submit reports to the authorities on sheets of prenumbered paper, obtainable from official stationery offices. The sheets are almost blank, except that they are numbered consecutively. This running number is known as the CUI number (in Spanish, correlativo único de identificación, also known in Peru as número de folio).
This enables the authorities to ensure that reports are submitted in full.
Use
In the R/3 System, some of the reports for Chile and Peru include a field for the CUI number on the selection screen. You only need to fill out this field when you print out a good copy of one of a report on the preprinted paper. What you enter is the CUI number printed on the first sheet that you are going to use. The system prints the running CUI number on every sheet, so that each sheet shows the CUI number twice – the preprinted number and the number printed by the system.
For the system to number the pages correctly, print out the list directly from the report selection screen by choosing Program ®
Execute and print. The numbering does not work if you execute the report by choosing 
on the selection screen and then print out from the result screen.
