Regarding workcenter capacity and scheduling

[ashutosh_saraf]

Hi Experts,

I have created a workcentre and maintained all formula's for each activity in the workcentre.Now what I want is that, while confirming the activity , If workcentre gets overloaded beyond tolerance limit then it must issue a warning message and wont allow us to confirm that much activity.

Case 2:

If capacity is overloaded then the timeframe also should mave accordingly as automatic scheduling.

your valuable suggestion would be highly appreciated

Sorry but did not understood case I. I am not clear why you require message while activity confirmation that work center is overloaded?When you are confirming an operation that means the operation has been physically already taken place and now you are updating the same in system.Also when you confirm a activity, the capcity load for that operation is reduced automatically. Can you please elaborate what really is required in case I ?

Case 2: SAP R/3 capacity planning just provides you information whether a work center is overloaded or underloaded. It is completely manual to do the capacity levelling and rescheduling the operations. The automatic adjustment to the capacity load is not standard functionality in SAP R/3 capacity planning.

Suppose a case is like this.

capacity is 100 per day and confirmation is 200 which is overload confirmation.

At this case can u tell me some contingency plan.

Hi Ashutosh,

Please check work deviation active & duration deviation active check boxes in confirmation parameters. Based on these settings, the value for work deviation/duration deviation is taken into consideration in the confirmation.

Once the activity is confirmed, actual work, actual cost, actual dates are updated and capacity for that activity is reduced (this capacity now can be utilised for other activities based on requirements).

Not sure if this will check capacity - it is only taking the difference in the confirmed value versus the value entered in the NWA, nothing to do with capacity

You can check the configuration for capacity availability check - but this is only applicable to assign the work to a work centre

The way I see the solution is to use an exit on confirmation to carry out capacity check

Yes, there can be solution by using some customization.

But what I do not agree that during confirmation it should give message that work center is overloaded. The confirmation means that activity has physically happened and now you are informing the same to the system. So where does the question comes whether work center is overloaded or not if the activity has already taken place?

I think please relook at this business requirement.

HI mahendra,

can you please tell how we can achieve what you have mentioned in CASE 2 above. To automate either through config or any other method susch athat SAP can automatically readjust teh requirements on to the next available date in termes of capacity when the requirements are overloaded on a given day.

Thanks

Hi,

Work center capacity and activity confirmation both are different entities and this is what I guess. Please correct me if wrong.

Let me put it this way...

Work force is assigned at work center level which let you know the total capacity being maintained at referenced work center. If some one asked me about what is the capacity of work center A, then my reply is 64 hours/day (10 persons with 8 hrs each and performace 80%). Thats how we derive the capacity of WC.

Now coming to Activity confirmation: for example you have planned hours of 100 on NWA and keep confirming periodically. When you cross the limit of planned 100 hours system gives a warning that activity is already confirmed (I mean reached 100% of planned work) but still allow you confirm beyond planned hours.

In combined view of WC and NWA, system never gives any kind of warning message even if you going beyond the planned hours on NWA.

As Mahendra pointed out, capacity evaluation and levelling being done manually and there is no automated process available unless you have developed program which takes care off.

Case2: Capacitiy overloaded or underloaded, capacity levelling to be performed basing on available capacity at work center level by manually. 

The time frame adjustment (I assume you are talking about automatic scheduling), if activity confirmation is less than the planned distributed value, whenever system schedules automatically and let you know ETC (Expected time of completion). for that you have to select the automatic scheduling check box at NWA.
