Cycle Count scheduling logic in Oracle EBS


Purpose of this document is to share the scheduling process I learned from the Cycle count process.


It starts with:

Derive number of working days in the interval

System derives number of working day base on below values of Cycle count definition

  1. Start of schedule date (say 1-Jan)

  2. Inactive date (Say 31-Dec)

  3. Calendar (5-days a week + 11 additional holidays)

  4. Frequency of schedule (say daily)


So, going with our example number of working days would be 250 (365-104-11 = 250 working day)


Derive number of parts to be scheduled per day

Now consider we have total 11,000 parts numbers of which 1000 part numbers A-Class, next 3000 part numbers are B-Class and remaining 7000 part numbers are C-Class


Class

Number of parts

Times to be counted

Number of parts to be scheduled per day

(Number of parts x Counts per year / number of working days)

A

1000

4 times a year

(1000 x 4 / 250) = 16

B

3000

2 times a year

24

C

7000

1 time a year

28


Based on above calculation system will scheduled 16 parts of Class A, 24 parts of class B and 28 parts of class C on one day.

On 1st day it will pick C-class 28 part of 7000, 2nd day it will pick another 28 parts from 6972, 3rd day another 28 parts from 6944 parts and so on.


Parts which need to be counted multiple times, there is a bit different logic. Oracle tried to split the counts of the same part number is different quartiles or halves. Example the part to be counted 4 times year has its one count in each of the quarter. Oracle check how many time the part is already counted and then picks it for scheduling. In our above example: 250 days will be divided into 2 halves for B class parts and one count in each half will be scheduled and for A class there is be four equal portions of the duration and each count of an part will be scheduled in each portion.

Every time system picks the part for scheduling based on algorithm; it populates that part entry in MTL_CC_SCHEDULE_REQUESTS table so that next time it will pick parts from remaining set of part numbers.


Then it checks conditions like if user want to count parts which have ZERO quantity based on ‘Count Zero Quantity’ check box in ‘Serial and Schedule; tab of Cycle count definition. If this check box is not selected, then the part is selected by scheduler for the day will be shown to user for entry only if it has on-hand available in the subinventories selected in ‘Scope and Control’ tab of Cycle count definition. 

Example: Say scheduler picks say P1, P2, P3 part numbers for today and P1 do not have any on-hand, P2 has some on-hand but not in the subinventories selected in scope and P3 has on-hand in any of the subinventories selected in scope. In such case

1. If ‘Count Zero Quantity’ check box is not selected then user will find only P3 appearing for counting today.

2. If ‘Count Zero Quantity’ check box is selected, then all three part numbers will be shown to user for counting. User may enter zero if the part has no on-hand, but he will be forced to do count and confirm.

We can use “Cycle count schedule requests report” to find which part numbers were picked on which date, all may not appear for Cycle count entry if ‘Count Zero Quantity’ check box is not selected.
