Field help (CRIDMFGBD) 

This field displays a change request ID if this product, or the specific version or revision of this product is associated with an 'active' change request. An active change request is a change request at the planning or implementation stage of the processing cycle. A warning icon is displayed adjacent this field.

If a warning icon is displayed you should consider delaying this work in progress transaction for this product until the change request identified is closed. At that point a change to this product will have either been seen through to its conclusion and the change delivered, or the change request rejected. You will not, however, be prevented from progressing a transaction should you decide to do so.
