message raised:Document is not valid on explosion date when create production order.

When you create a production order you got a  warring message：

****************************************
Document: T-22720,
Document part: 000,
Version: 00
is not valid on explosion date.
No further valid versions are available. Should
the document link be transferred anyway?

Choose yes or no.

We can found some useful information ,it  seems relate to DMS (document manage system) .

First ,find out the material number which  you want to create production order .then go to MM02 - additional data - document data
you will found a document link to this material ,e.g ,document number T-22720 ,document type DES so on .
According to previous information ,we knew the warring message is cause by the document valid date ,so we have 2 choice:
1、release this document .(use CV02N)
2、remove the link between material and document .(MM02 - additional data - document data)
