Hi,
I got the below Tips from CRM Community,
Here is an idea (it make need a little effort to make it fully work) - *Note this won't work with the editable product grid functionality
On your line item records, create a new decimal field (allows 0 -100) for the line's discount percent.
Add it to the form, make the existing Manual Discount field read-only but keep it on the form.
Add some JavaScript on the OnChange event of the new Discount Percent field to figure discount amount automatically and place the result in the manual discount field. Once the record it saved the built in calculations should still work as expected.
JavaScript would be similar to this:
Share
Reportfunction DiscountPercent_OnChange() {
var discPer = Xrm.Page.getAttribute("new_discountpercent").getValue();
if (discPer === null || discPer === undefined) {
Xrm.Page.getAttribute("manualdiscountamount").setValue(0);
}
else {
var manDisc = (Xrm.Page.getAttribute("priceperunit").getValue() * Xrm.Page.getAttribute("quantity").getValue()) *
(discPer / 100);
Xrm.Page.getAttribute("manualdiscountamount").setValue(manDisc);
}
Xrm.Page.getAttribute("manualdiscountamount").setSubmitMode("always");
But the below error faced when it is running. Please advise
