Hello,
I checked the definition of the function module MCEX_UPDATE_03 (through the transaction SE37), and this is not a V2 update module. It is a V3 update module ("collective run").
I believe that the status of this update requests, at SM13, are "v2 processed", no?
This means that both the V1 and V2 part of the update request has been finished and only the V3 part is pending.
V3 updates are not processed automatically.
Read this SCN document for guidance with V3 updates:
Processing pending V3 update requests
Regards,
Isaías
