Changing Plants yet must prevent the Change in Dates

[Former Member]

Hello All,

A few Plants of the Company are live on SAP on vers 6.0 from the past 2 years while other Plants are going live on SAP now.

Situation:

At Cut-Over time for the New Plants, there will be existing Open Sales Orders in SAP. For these we would be changing the Plant from the existing to the New Plants.

Constraints:

a) When the Plant is changed, the ATP Dates get triggered and changed. However, we would like to prevent the dates changing.

b) The New Plants will have stocks existing when the Cut-Over is done for the Open Sales Order Lines. So, there is no way to zero out the stocks and change the Plants.

Question / Help Needed:

Are there ways to prevent the dates from Changing when changing the Plant ? This solution is requested urgently.

Reason:

These Dates are the Requested Dates from the Customer and the Promised Dates to the Customer based on ATP. So, we would like to retain the same dates to measure On-Time Delivery.

Research / Solutions from our side:

Would anyone have any other suggestions besides these listed below as 1) and 2) ?

1) Just before and during Cut-Over, make the Material Masters not relevant for ATP (Check = "KP") . Change the Plants on the Orders. But after the Cut-Over and Go-Live, convert the Material Masters back as "Relevant to ATP". However, this appears to have major drawbacks because on MD04 it might not show later due to changes in the ATP and some other issues.

2) We found a solution on this forum in this following link, however, we do not find this solution do-able.

Hello Lakshmipathy and Kapildev,

Thank you for the suggestions. I have awarded points for a very helpful answer to both of you.

*Solution 1*:Changing the Schd Line Categories to CN and after that changing the Plants :

Result : It still changes the Dates. It was tested.

*Solution 2*: Changing the Requirments Class: I will test and inform.

Meanwhile any other suggestions are welcome. Your help will be appreciated & rewarded.

Thanks,

Hi,

Don't do change schedule line and plant.

Rather what schedule line and requirement type you determining for that both stop availability check temporally.

The standard schedule line category is CP which flows to your sale order and this triggers the date once you change any data at item level. You can avoid this by manually changing the schedule line category to CN, provided it is assigned to your item category in VOV5 under the tab "MSLCa"

thanks

Hi,

If you don't want to change dates then stop availability check temporary for the schedule line and requirement class.

So dates will not change and system will not confirm qty. and will not propose dates.

IMG >> SD >> Basic functions >> Availability check and transfer of requirement >> Availability check against ATP >>

Define procedure for schedule line

Define procedure by requirement class
