Please tell me which master data sources to be activated for data source 0FI_GL_1 in ECC side and how to check it ?
There is no direct way to check this..
Usually we activate all the master data sources in the FI-IO application component.
Another way is just see what all characteristics are there in your datasource FI_GL_10.
And based on your requirement activate their attribute and text datasources eg. 0account_attr, 0account_text.
