Hi Anand,
I think we can use this classical approach for all scenarios (irrespective of SAP/Legacy) and it should be like this -
i) Try to shot-close all the open items to as small list as far as possible. But realistically still there will be some half-baked PP orders, SD orders, etc available in the system, and for migrating it definitely some approach needs to be put in place.
ii) In case if some PP order is started in As-Is system, and some partial confirmation is done, then that GR stock is already classified in the As-Is system as unrestricted or blocked. So no harm in pushing these stock directly using MvT 561 or 565 without inspection lots created against them. And this becomes the starting point for further analysis.
iii) In the existing system if no QM is implemented now then only after cutover and stock upload, QM views needs to be implemented with insp type 01 , 04, etc. First add insp type "05" during cutover and add no other inspection type at that time. Post cutover after stock validation is done pls remove insp type"05" and add "01", "04", "89" etc. If we do not have Q-implemented in As-Is system, so our case becomes simpler, and only MvT 561and 565 should be ok.
iv) For example, if there is an order of 100 PCE there in As-Is system with GR batch B1, partial GR posted of 20 PCE, then pls check if it is possible to shot close these orders there in As-Is system only, and create new orders in To-Be system for 80 PCE with the batch B1. Note that if for this new case 04 inspection type will be activated, the results can be added and QC for finished material can be generated for inspection lots 04.
Whereas, for the migrated material/batch, the inspection certificate (with migrated results) can be created from QC22 for the inspection type 05.
v) All logistic processes in the new system needs to be recreated afresh post cutover, like new sales order for differential quantity, new PP order with differential quantity, etc.
vi) Please note that as the As-Is and the To-Be systems are two different landscape, so partial transaction performed through PP in previous system will not impact here.
vii) It case if it's business critical to migrate the old production order form As-Is to To-Be system, where some operations were already confirmed, and some more pending to be confirmed -
a) Create a new PP order in To-Be system (Order with ext number range or internal number range)
b) activate 04 inspection type.
c) ONLY post the remaining confirmations which were not posted before in the previous system and consume remaining components against only these operations (MvT 261).
d) post partial GR or Full GR and this time a new inspection lot/lots will be created (with internal number range, based on insp lot control setup) And now on there will be Q-managed stock henceforth.
e) To generate a QC necessary for supporting a delivery, for this type of cases is a bit tricky you can follow the below process -
> If the migrated batch number is same, add the quality results only in the new inspection lot and fire QC using QC22 against inspection lots form QA32.
> In case the As-Is GR batch and To-Be GR batch is different, you can get two QC's one for the 05 inspection lot (MvT 563) and one for the new GR batch with inspection type 04 (MvT 101/131). This case will only be valid for migrated batch stock and rest will follow the normal process.
NOTE: As I said before, the approach whatever you adopt needs to be tested before hand, and ensured that the process is working as expected.
