non leading leadger

hi

in the case of leading ledger you take ' 0L ' in the pop up box,

but in the case of NON LEADING LEDGER after click the IMG ACTIVITY in the pop up box what should i take for LEADGER?

where should i configure this value?

2.for leading and non leading we are giving fiscal year and posting period- where to give this separately how to differ this , we are giving for this both in OB29 AND POSING PERIODS

HOW IT WILL DIFFER?

THANK YOU
