Validation Rules for Issue Code "T"

 

The following validation rules apply for parts having a "T" issue code.

1.   The part must be a JIT part.  Automatic receipt/issue works only in a JIT environment.

2.   The part must be a manufactured or transfer part, but not a build-thru part.  Build-thru parts cannot have requirements.

3.   Only the following planning policy codes are valid:

      6 (partial) - for manufactured parts
1 (as required) - for transfer parts

4.   Because the receipts are issued automatically, the part's relief type must be point-of-production (which means that the receiving and issuing locations are identical).  This is because in a point-of-use environment a user must manually record the receiving location because the component can be received in several locations.

5.   The part's producing location must exist.

6.   The part must not be lot controlled, because specific transactions are required to issue lot-controlled parts.

7.   The deduct point operation must be blank.  Deduct components are not backflushed because a specific transaction is required to issue them (i.e., deduct operations are not automatic).

8.   The component offset days must be zero.  The date that the multi-level backflushed component is issued must be the same date that it is received.
