Issue with Amount in the Invoice

Hi,

I have run the trasaction for generating the invoices when checking the amount billed I could find a significant difference difference in the amount. On further analysis it was identified that in the table ERDK which is the table for invoices had failed to update the negetive values in the payment form amount. Can anyone let me know hy this is happening and how I can find the root cause for the same?

Thanks.

Anand,
