V1 806 - Internal Pricing error

Question

Pricing error message v1 806 before saving 
Unable to save Purchase orders. Get the internal pricing error.
Internal pricing error
Message no. V1 806
The error started happening after the PO user exit was changed to
validate the net price if either the delivery date or net price
changed. The user exit reads the price from PO inforecord to check
price entered, it pops up error if price not within the allowable
limit. Initially user exit was only checking if the PO net price
changed. Now if the delivery date is changed, then the price is
validated against the inforecord conditions. When we change the date back to the original date, SAP pops Internal pricing error. But when the save button is hit again, PO is saved without any error. when I went through the help, this is the message displayed -
Diagnosis:
The program link between tables KOMT1 and XKOMV using the XKOMV-
IX_KOMT1 field no longer works in the pricing program SAPLV61A. This
could be because the PRICING_REFRESH function module has been called up
from another function module, even though you did not require it.
Please help!!
