Standard Cube for datasource 0FI_GL_7

Dear Experts,

1) Is there any standard infocube for the datasource 0FI_GL_7?

2) Now I have a requirement to develop a GL report.

I looked into the BI Content and found 2 relevant datasources: 0FI_GL_6 and 0FI_GL_7.

I think 0FI_GL_6 gets data from GLT0, and 0FI_GL_7 gets data from GLFUNCT.

May you please explain a bit what is the difference between these two datasources and these two tables (GLT0 and GLFUNCT).

Thank you so much.
