Field help (CNAPYR) 

Principally used for reports and inquiries, the pyramids are used to characterise the summary (roll-up) level and order of the information to be retrieved. This process is automatic and is updated retroactively.
Depending on the objectives of analysis and synthesis, it is possible to assign each general or analytical account to several pyramids. On the other hand, an account can only be attached once to a pyramid (to a group of accounts).
It can also be done within the specifications of the groups of accounts.
