<p>OP Bill report is generated based on OP Bill dates and Receipt report is generated based on receipt dates.</p>

<p>- It is possible that for a given date, bill is prepared but amount is not receved</p>

<p>- Similarly it is possible that amount is received on a specific date for bill of previoius date.&nbsp;</p>

<p>&nbsp;</p>

<p>So, the direct comparision is not relevant</p>
