BOM Cannot be changed, open work orders were found
We created several Assembly BOM's back in 2005A. We have since upgraded to 2007A and would like to change these BOM's to Sales type. Currently there are no open sales orders for these BOM items.
When I try to change the type and update, I get the error, "BOM Cannot be changed, open work orders were found." I assume this is referring the the old terminology for production orders (for which there is also nothing currently open). Is it possible to change the BOM type?
Your first idea is good enough. The options are not too many since you can not delete the items or BOMs if they have history. The only option left is changing something in order no user could mistakenly use it.
