Custom Cycle counting Solution

Hi All

My client would like to implement a custom cycle counting solution, however I am not sure if it is possible. I would really appreciate some help. They do not want to go the standard cycle counting route.

1. Business requires the development of a Cycle Counting Calendar to block off days where regions cannot count. This will cause the system not to generate picking documents for that specific week(Only the calculated days which no counting can be done)

2. Business requires a development in SAP to show the stock counted per week and where adjustments were made in terms of the number of line items. A the moment transaction ZMI24 provides this information but only in terms of value and not line items.

3. We require a change in the definition or calculation of the ABCD indicators that are used for CYCLE counting. At the moment transaction MIBC calculates these indicators using any movement(In a given time period) in the plant and multiplies it with the value. We would like to have it linked up to the PIC inventory policy definition.
