Thanks Raman.
The appropriate DataSource depends on whether you are using Classic G/L or New G/L.
Classic G/L:
I suggest to use DataSource 0FI_GL_6 (which replaces 0FI_GL_1 and is delta-enabled). The base table is GLT0.
New G/L:
I suggest to use DataSource 0FI_GL_10. The base table is FAGLFLEXT.
Best regards,
