I`m trying to understand how to use Business Content by SAP Analytics Cloud, some FI content in particular (Finance, model SAP__FI_GEN_IM_GENERALLEDGER). It was said in SAP Help that I can change master data in SAP_FI_GEN_GLACCOUNT (this is account dimension in the mentioned model) if needed. For that I can use "API_GLACCOUNTINCHARTOFACCOUNTS_SRV" OData service but I don`t really understand how I can retrieve data from S/4HANA using it. I know how to consume CDS views but it seems to be something different. All I found on that is A_GLAccountInChartOfAccounts (which was transformed by me into consumption CDS with mistakes), it is somehow connected with the mentioned OData service.
The question is how to use API_GLACCOUNTINCHARTOFACCOUNTS_SRV to retrieve master data of CAO and update public account dimension SAP_FI_GEN_GLACCOUNT? Is there any other way of retrieving master data of CAO from S/4HANA?
