Why field CPS is mandatory in EDIFACT?

According to the specification of EDIFACT, CPS is mandatory in DESADV. https://www.stylusstudio.com/edifact/D97A/CPS_.htm But we don't have any data to send in CPS segment. Can we construct a DESADV message, which contains LIN and QTY segments in segment group #15 without the CPS segment? https://www.stylusstudio.com/edifact/D97A/DESADV.htm#SG15

According to D.97A standard, CPS is optional with a max uses of 1 and 9999 on the loop. - Andrew
the only thing mandatory about a CPS segment is the hierarchical id. So if you have only one package, you just add a single CPS segment with hierarchical ID 1 and add your line segments under that. - Dirk Trilsbeek

CPS is the trigger segment indicating the start of SG10. SG15 is a child of SG10 so while it's valid to construct a DESADV without any CPS segments, it would not be possible to include any LIN segments or any other detail information in that message.

You can see this in the Message Structure at the bottom of the page you linked to earlier: https://www.stylusstudio.com/edifact/D97A/DESADV.htm#part4.3

CPS indicates packing structure, with the top level covering the entire shipment, so the simplest structure contains a single CPS with all of the LIN (etc) below that.
