How to remove Batch Management Check in the Material

Question

I have one requirement to remove batch management check in the materials which should not be deleted.
I created a testing material with batch management check on and put in material through 561, then did good issue for
scrapping to remove the stock out. So existing stock is zero in Material Master.
Then deleted the batch in MSC2N by putting all the delete checks on. There was just one batch created for the material.
Then ran transaction MM74 to archive, the spool request is as below:
MCHB: 000000000010000498 2002 1002 D000000200 entry archived                             1 000000000010000498
Archiving Session Number                                  000004
Number of Written Data Objects                                1
Size of Archiving Session in MB                           0,011
Proportion of Header Data in %                             96,7
Then in MMPV changed the closing period to may as all the postings were performed in april.
Now still when I go and remove the batch management check in MM02 Purchasing view, still gives we DISPLAY ERROR message:
The batch management requirement cannot
be changed for the follow
Batches already exist.
ANY IDEAS why its not allowing me to remove the check as I guess I have performed all the steps required.

Answer 1

Check whether the batch master is still exists in MSC3N .if it ia archived it should not be avialble in MSC3N
Refer note:30656
Reason and Prerequisites
The message that stocks still exist refers not only to stocks in the current period, but also to stocks in the previous period.
The reason for checking previous period stocks is that postings can also be made to the previous period when entering goods movements. This would result in inconsistencies if the base unit of measure had meanwhile been changed.
Solution
Check whether stocks still exist for the previous period by displaying; for example, the plant stock view or storage location stock view of the material. You do this by selecting "Extras -> Previous period -> Prev. pd SLoc. stock or Prev. pd plant stock".
If previous period stocks exist, you can make a withdrawal posting as follows:
1. Post the same amount to current period stock (for example, using movement type 561) so that previous period stock and current period stock are identical.
2. Make a withdrawal posting in the previous period for the stock together with posting date (for example, using movement type 562).
You can now try to change the base unit of measure or the batch management requirement indicator again.
Since the posting of the previous period values to zero is identical with posting to the stocks of the current period, you should reverse the above stock postings (that is, the stock from the previous period should be booked in again) to make sure that the stock values from the previous and the current periods correspond to the state before the change. However, note that the postings are then carried out using the changed master data from the current period (for example, account determination and so on)
