Consistency Check in the Derivation - Example

The following examples explain the different situations that are recognized by the derivation’s consistency check:

Starting point:

Order 123 produces batch C using component batches D and E .

Order 124 produces batch A using component batches B and C .

Derivation:

Batch A receives the expiration date.

The selection rule for the expiration date is minimum.

A derivation took place, in which the batches B and E each sent their expiration date. The expiration date of batch B has been transferred, since it is smaller than that of batch E.

Result:

Batch A ’s expiration date is now 04.20.

Example 1:

Change:

Batch E is replaced by batch X in order 123.

The consistency check converts the status of this derivation due to the change.

Example 1.1:

The expiration date of batch X is 4.1 :

The expiration date 04.20 of batch A is now incorrect and must be corrected to by the new value 04.01. After this correction, the status of the derivation can be set to manually confirmed.

Example 1.2:

The expiration date of batch X is 5.1 :

The 04.20 in A is still correct. The status of the derivation can be set to manually confirmed without any further corrections.

Example 2:

Change:

Batch C is replaced by batch X in order 124.

The consistency check converts the status of this derivation due to the change.

Batch X was produced from batches Y and Z . Batch Z would also be a sender for a new derivation.

Example 2.1:

The expiration date of batch Z is 4.1:

The 04.20 in A is incorrect and must be corrected (new value 04.01). After this correction, the status of the derivation can be set to manually confirmed.

Example 2.2:

The expiration date of batch Z is 05.1:

The 04.20 in A is still correct. The status of the derivation can be set to manually confirmed without any further corrections.

Example 3:

Change

Batch C is replaced by batch X in order 123.

The consistency check converts the status of this derivation due to the change.

Batch C is still entered as a component in order 124. Batch E is no longer contained in the batch where-used list for batch A . You can only make the necessary correction after you adjust order 124. Until then, in this example, the 04.20 in batch A would formally be correct.
