I am currently learning "Designing Stories in SAP Analytics Cloud" under which there's a sub topic "Table configuration". In their image illustration, I can see the option "Add Measures/Dimensions" 
. However, while on creating a table in a story I only get the option - "Add Dimension"
Why am I not able to see the "Add measures" option? I am not sure if I am skipping any steps here? what could be the reason, please enlighten me if anyone has faced something similar or has any idea about the same.
Is "G/L Account" a dimension or the model account? If it's the latter you'll want to click the Manage Filters button (shaped like a funnel, next to the X in in the G/L Account box). This should open a window to select the measures in your model.
For calculated measures click the 3 dots and select Add Calculation.
