@mehmetsahin1755 your question is not very clear. Can you pls elaborate what you try to achieve here. Is it the PDF file attached to an Inventory part. How does this part connected to the work order? is it a material line in Work task?

Ok. I xplain with detail.  I added a file on InventoryPart. 

After, I want to see the file in ShopOrder. The file can not connect in ShopOrd.

However, the document below says that this process can be done. 

@mehmetsahin1755 for that you need to create an Object Connection transformation rule between the two objects (need to find the LU name of each object and set it in Object Connections page in solution manager). So that document connected to the inventory part will be visible Shop order materials for the same part. Source will be the part and target will be the LU loaded in the shop order materials.

In the help documentation search for Object Connection transformation, you will find an about description with details how to set this up.

Thank you for your information.
