Workbook issue. Wont' allow anyone to enter data in the OELI workbook.

Hey Gang!

Don't suppose anyone can remember how to recreate the Workbook DDF's to see if this will fix my problem.

When I do a "rebuild" in the WB setup it comes back clean.

I tried adding a field to OELI WB, No error. 

I tried removing that field and reorganized. No error.

In the OE module add a new order, a line item, click on the OELI WB, It opens and let's me enter data. When I click the SAVE button... I get the error.

I am pretty sure that you just delete of of the DDF files, go into BV add a field to the OELI and reorg for it to rebuild the DDF

Which DDF do I delete???

Any help would be greatly appreciated.
