Add-on in Extended ECM for SAP Solution project

Obed

We are in the initial stages of an integration project of OpenText Content Server version 22.1 with a SAP ERP 6.0 NetWeaver 7.4 EHP 7 system. We have already contemplated and planned everything, however we have a slight doubt which we would like you to clarify for us: According to the guide (https://knowledge.opentext.com/knowledge/piroot/_org/docovw.htm?manid=ERLK210400-IGD) it only refers to the following add-ons:
Archiving and Document Access (SAP Add-On) (OTEXBAS)
Extended ECM for SAP Solutions (SAP Add-On) (OTEXRL)

However, in our opinion, the OTEXERP Add-on is also important for the integration since it does not provide advanced information and all the required functionalities of Extended ECM.

Additional Environment Details:
OpenText Version: Content Server v22.1
SAP ERP System 6.0
Integration Objective: Implement Extended ECM to manage and archive documents linked to SAP business objects.
