Quantity Stored KF calculation logic

Hi,

In the standard planning book 9ASNP94 (Planning view SNP94(2)), there is a key figure 'Quantity Stored' (9ASTOCK).

Please suggest what is the source of the information stored in this KF & where the calculations are stored. I could not see any Macro for this purpose.

I also understand that this KF may be copy of KF 'Projected available stock' but i am not able to get more information on this.

Request to provide your input on this.

regards,

Mohit
