QM Open Note

QM Open Note is a blog post series about topics, which can be useful when working with Quality Management.

Overview

Current blog post contains some scenarios with code places, where the Next Inspection Date for a batch is updated (MCHA-QNDAT).

In detail

Documentation of Data element ‘QNPDAT’:

“Next Inspection Date

Defines the date for the next recurring inspection for the batch.

Dependencies
There is a program that runs on a cyclical basis for monitoring the date. If necessary, this program creates an inspection lot.

You can also use the following functions for deadline monitoring:

• The job overview display function
• The job planning maintenance function”

Scenarios:

1. Usage decision is made for an inspection lot (transaction QA11):

Known problem & solution

Transaction QA07 (Program RQAAAS10) can be used to trigger recurring inspection / deadline monitoring of batches.

There are some requirements for the successful selection of batches according to the program documentation:

“…

The batch master data corresponds to the selection conditions.
Only those batches that fulfill the following conditions are examined:

• The batch status is “released”.
• The unrestricted-use stock is greater than zero.
• The stock is not in an HU storage location.
• The stock is not special stock.

…”
