How can i create an maintenance work order and manually associate with work requirement

Summary:

During conversion, we have a lot of open work orders generated based on Preventive Maintenance from legacy systems (and then assigned to resources) that we want to convert into Oracle.

However, if we create those maintenance work orders directly or use FBDI to load maintenance work orders with work definitions, it's not tied to work requirements and maintenance program.

So maintenance program will possibility generate a duplicate work order and not recognize that an open work order was already created on this asset from that requirement earlier.

How I can create an maintenance work order and manually associate with work requirement so that MP not create duplicate work orders when an open work order is already there?
