Before opening a Service Request at SAP (step 1 of the following) : (source : https://help.sap.com/docs/SAP_S4HANA_CLOUD/a630d57fc5004c6383e7a81efee7a8bb/524b2eb9d76747f9a0f226073abf3fd6.html?locale=en-US), wich I guess is a ticket to open :
A/ I wish I could process app. "Check Your System Readiness". I understand that I can only process this in the source system whenever I want (source : https://help.sap.com/docs/SAP_S4HANA_CLOUD/a630d57fc5004c6383e7a81efee7a8bb/e92c1abd072948beb6acd525f321f475.html?locale=en-US : Note : It is only possible to use the Check Your System Readiness app in the source system).
B/ In step 2 of the screenshot, it is said that SAP will perform a readiness check on the target system (so Q to my understanding, and not P). So my understanding is that doing what I suggest in point A/ (point A/ should only be done in P according to sap help portal's Note) is different from what SAP intends to do in step. "1. Service prerequisite" which is in Q.... Am I correct ? That would justify that I must perform a "Check Your System Readiness" in P (see point A/), but I am surprised that this step is not included in the screenshot.Could you clarify when is the "Check Your System Readiness" in P to be done ? and will it bring different information from SAP's system readiness check (step 2. Service Prerequisistes) ? Should I perform a "Check Your System Readiness" in P before "step 1. Service Request" ? And ultimatlely do you know how long it can take as apparenly it will impact the performances in P ?
