Field help (ADSMEM) 

This parameter corresponds to the memory size used for the local data during the execution of the server process. By default, 16 Mb is proposed, this is a reasonable value even if the minimum value possible is 4 Mb. It is possible to increase it as a function of the maximum number of lines used for the large tables in memory (orders, invoices, postings). The higher the given values in the Screens tab, the greater the need to increase the necessary memory size. The system variable maxmem is used to identify the current value during a session.
