Lok,
Here is the list I use. We have a GATP, DP, and PPDS implementation. If you are using SNP, there may be more stuff. Also, if you have more than just '000' active version, you may have to remove certain data items from all versions before you can delete:
1. ERP - Deactivate ALL CIFs. Use model search in ERP until ALL CIFs attached to the SCM instance are inactive. This is a good time to also DELETE any older inactive models that may be hanging around from experiments or whatnot, just for general housecleaning.
2. SCM - Run Delta reports (transactional data) /SAPAPO/CCR - CIF_DELTAREPORT3. Delete items in APO that have no active models. This may have to be done again after all CIFs are re-established at the end.
3. SCM - Report /SAPAPO/DELETE_PP_ORDER u2013 delete all orders, including external.
4. SCM - Report /SAPAPO/SDRQCR21 clean up any inconsistant requirements
5. SCM - Report /SAPAPO/SDORDER_DEL clean up all sd orders
6. SCM - Delete ALL temporary quantity assignments /SAPAPO/AC06
7. SCM - Correct LiveCache inconsistancies ALL data Txn SAPAPO/OM17
Now we start deleting master data stuff. In some cases you can use the regular transaction, in some cases it is easier to just use WUF. If you delete using WUF, make sure you include the items that have no use.
8. SCM - Delete all PPMs (ERP Production Versions). Mass tool SAPAPO/PPM_DEL sometimes works. I have gotten short dumps before. Mostly seems to work if you delete no more than 1000 at a time.
9 . SCM - Delete existing Resources (Work Centers) /SAPAPO/RES01
10. SCM - Delete External Procurement relationships (purchase info records) - SAPAPO/MTI2
11. SCM - Delete Transportation lane material assignments, /SAPAPO/SCC_TL1
12. SCM - If any remaining orders prevent deletion of product masters, try /SAPAPO/VS_CONS_CHECK
13. SCM - if you elect to delete a material, all safety stock must be set to zero in the Product master prior to deleting. Run SafetyStock heuristic when done to remove SS orders, or wait for the nightly job.
14. SCM - Consider if Product Location masters and Product masters need to be deleted. Delete as necessary. USE WUF to find any stragglers. You must be relentless.
15. SCM - If there are any existing orders which are preventing the deletion of any product masters, you will have to find them using SAPAPO/OM16 and then delete them using /SAPAPO/OM_DELETE_INCON_ORDERS. This is a last resort!
15. SCM - Delete any Location Masters as necessary. /SAPAPO/LOC3.
16. SCM - DELETE any IM Queue Errors, BOTH DIRECTIONS now. After each of the subsequent steps REPAIR any new queue errors. This may have to be done several times. /SAPAPO/CQ
17. SCM - One more shot at CCR. Delete any errors 'No active models'. You should now be suspicious of any other errors reported, since SCM is now supposed to be empty. Investigate and correct any remaining errors.
18. SCM - One last shot at correcting LiveCache inconsistancies Select ALL items, even if you don't think you are using the item. Txn SAPAPO/OM17
19. ERP - Re-Create/Re-Activate Master data IM's in proper order. Don't just re-activate your old IMs. This is also a good time to examine your IM Variants to see if they still make sense. For any Queue error, STOP, fix the underlying error before proceeding. It is not OK to just delete the 'bad' queues and keep going. You only delete an errored queue AFTER you have fixed the logical problem. Then, delete the queue, re-create and re-activate the IM. Activate in the following order:
a. Plant
b. Material (then Mass change SCM Product masters as necessary if needed in your environment)
c. Work Centers
d. Versions
e. PurchIinfRecs/Vendors
20. ERP - Create/Activate Transaction Data IM's
21. ERP - Create/Activate ATP IM's
22. ERP - Create & schedule regular Jobs
23. SCM - Create & schedule regular Jobs
