In SAP S4/HANA Public Cloud, What is A10 and how do I know if I’ve made any postings on it?

Dear All,
I am trying to implement Group Reporting in SAP S/4HANA Public Cloud based on 1SG test script.

Another note from SAP: Group Currency once defined in Create Version from Reference Version, cannot be changed anymore. Setting group currency to EUR is only for the purpose of the testing in this test script. If you want to maintain your own group currency, please use your own data setting and files instead of the ones we provide. If you have already made postings on A10 with other currencies except EUR, please create your own version for the following testing and adjust all the data files used in this test script accordingly.

What is A10 and how do I know if I’ve made any postings on it?
Thank you and best regards,

The group currency in SAP pre-delivered cons. versions is determined by cloud customers when specifying the group currency in "Primary Financial Settings". Group currency varies customer by customer. 1SG test script provides data sets and expected consolidation result with group currency EUR.  To provide generic test procedures fit for all cloud customers, testers are asked to create a consolidation version A10 with group currency EUR manually following the instruction of 1SG test script. As the note said, this is for testing purpose with SAP provided data sets.
