My client needs 2 inspections intervals.
e.g. for first retesting should be fall on after one year, but second and onwards inspection should be on every 6th month.
Can this requirement be setup in the qm module?

Solution:

You may want to look at enhancement QEVA0003 (Calculate "Next inspection date" for batch).

You could setup the material master for the first next inspection date (1 Year). Then use the enhancement when future dates are calculated to use the 6 month period.

Note:

SAP doesn't support having different interval dates. This however isn't an uncommon issue in several industries.

The problem is where and how you define the various intervals. I had to set a system up for a pharm. firm once. In their case they had many different re-inspection "programs" a material could be on. We used a Z table to store the various programs and classification to track what stage of the program a batch was in.

If you have limited permutations, I would suggest using the material class 001 to specify various interval ranges. Create characteristics like INTERVAL_2, INTERVAL_3, etc.. Used the Material master inspection interval as the initial interval for when the batch is created.

Then in the user exit, look up the INTERVAL_2 value to calculate the next inspection date when the first re-inspection is completed. 

If you need to use a third interval, then you'll have to add a batch characteristic in the 023 class to track what interval value should be used next. Default it to 2 when the batch is created. 

Have the user exit increment it each time a new inspection date is calculated. The second time around it would use INTERVAL_3, the third time, INTERVAL_4, etc.. etc
