Cash discount amount cannot be posted

Hi All,

I am facing the problem at the time of Invoice posting. A error given below:

Cash discount amount cannot be posted

Message no. M8485

Scenario is:  PO Net Amount: 228,416.00

                      GL entries in the G/L Account tab:    781,389.00   Dr.

                                                                                 987,000.00   Cr.

                     CashDiscnt:  0.00

Total Amount showing in MIRO header level:  22,805.00

After simulating the same, showing the error line:  "Cash discount amount cannot be posted"

I had clicked on the help icon of the error message and found, below statement which is unable to understand:

"If you are entering an invoice, the following situation has occurre

The amount eligible for cash discount in the relevant credit memo items (987,030.00 INR) is larger than the amount in the relevant invoice items (984,705.00 INR) This means that a positive amount is posted as the cash discount."

Request you all to rid out from this issue. This is very very urgent.

Thanks in advance

Jayesh
