Steps to Reproduce:
When adding a new line item to a quote or order in a non-integrated Sage CRM system you may see the following message after you've clicked save on the line item:
"Validation Error - Please correct the highlighted entries".
But Sage CRM does not show the highlighted entries.
If you try add a "New comment line item" the following message is shown:
"Pricing Service is not available".
Make sure that the custom_sysparam “DontSaveOnPricingError” is set to ‘N’
update custom_sysparams set Parm_Value = 'N' where Parm_Name = 'DontSaveOnPricingError'
Then do an IISReset and test again.
