SAP B1 DTW EDG1

Hi, (SAP Business One 9.3)

Trying to update the specific BP discount for item groups.

So the BP Discount already exists for item groups and there is some item groups that manually have a discount matched to them.

So I believe all I need to be doing is DTW the EDG1 table however when I try this I get a error..

DTW - Setup Data - Inventory - Price Lists - Special Prices - Discount Groups

DiscountGroupLineCOllection in DTW and all source and target fields match up.

I get the error - Error while convert ObjectType 65171

It fails on the 1st column. See below for what is being used.

ParentKey LineNum AbsEntry ObjectType ObjectCode DiscountType Discount PaidQuantity FreeQuantity MaximumFreeQuantity AbsEntry LineNum AbsEntry ObjectType ObjectCode DiscountType Discount PaidQuantity FreeQuantity MaximumFreeQuantity

Hopefully someone can spread some light on this!

Thanks
