Suppose I plan a standalone group reporting environment and have two distributed S/4HANA and one ECC system. I expect to use GRDC (group reporting data collection) to collect data into the table ACDOCU in GR. I would like to know if it could accelerate the corporate closing processes such as performing intercompany, currency, validation, etc. before period-end close. I read some article and my understanding is that the prerequisites is that all external system must be loaded into the table ACDOCA in the same system with GR. It could not accelerate the corporate closing processes in my system landscape? or give me the better advice. Thanks
