CTM Explanation Log Messages

[former_member1058922]

Dear Experts,

We are in the process of analyzing the messages provided in the Explanation Log generated after CTM Planning run is complete.

Following are some of the warning messages followed with examples that have been included in the Explanation Profile:

1. Resource &3: No dispatching possible with duration &1 / capacity reqmt &2
   • Resource WHSD_F330_008: No dispatching possible with duration 25:02 / capacity reqmt 1.000

1. b) Activity &2 / Mode &1 cannot be scheduled
   • Activity 999900000004 999900000004 / Mode 1 cannot be scheduled

1. c) Demand quantity &1 falls below minimum lot size &2 of source of supply
   • Demand quantity 0.750 falls below minimum lot size 1.000 of source of supply

We are having a tough time to understand and rectify these 3 errors that frequesntly occur in our CTM Planning Run.

Request you to shed some valuable information on the same.

With Regards,

Harsh

Hi Harsh,

For 1st message check your resource.

For second message check your source of supply (PPM or PDS) and check activities and mode there, have you by any chance created the same in APO directly.

For third message it seems to be that it is because of use of fixed lot size, may be using lot for lot procedure will help here.

I would advice you to check your CTM master data in transection /n/SAPAPO/CTM01.

Hi Harsh,

Pl check the following SAP note for CTM explanation tool msgs.

https://service.sap.com/sap/support/notes/1711914

1. Resource Resource name: No dispatching possible with duration/capacity requirement.
Reasons for this can be that the duration of the
activity is too long to be planned on the resource, or that the capacity requirement is too high.
2. Activity Name of activity: Mode cannot be scheduled
Reasons for this can be that the required capacity is missing, or that it
cannot be planned with regard to time (for example, due to horizons, too long duration, and so on).
3. Requirement quantity is lower than minimum lot size of the source of supply
  - Minimum lot size defined in source of supply (PPM/PDS for in-house production) is also a valid constraint and the CTM planning engine does not generate a proposal if the demand quantity falls below the min lot size requirement. 

Thanks,

Rajesh
