Demand and receipts

[former_member205751]

hi

in SAP parlance we frequently come across two words Demands  and Receipts

list of all demands as for as i know are  are  customer demand ,sales order demand,demand from MD61 (pir),demand created from planning book .would you please list out all demands relevant to SCM you have come across so far?.

receipts are planned orders emerging from IHP,(inhouse production ),PR (procurement proposals) this is as far as i know

would you please list out all demands and receipts under the umbrella of SAP that you have come across in your practical working business environment  .cpz your answer will remove my confusion

i understand my questions would be silly to you ,but your inputs will help me gain a mastery over SCM ...if you look at SNP optimizer SDP94 screen you will find many demand items and receipt items  followed by total demand and total receipts-where are they emerging from i could see there is one "distribution demand (planned )  and distribution demand(confirmed) ,where it is emerginfg from.....am a bit perplexed about this demand and receipt theory.

please clear my confusion.....

Demand & Receipt Elements are MRP Elements in ECC and those map to ATP Categories in APO. To see the entire list of ATP Categories use configuration /SAPAPO/ATPC03. There you can see 4 types of Categories - Requirements (Demand), Receipts (Supply), Forecast (Demand) and Stock (Supply).

Any data in Order Live Cache (typically interfaced from ECC using CIF but could also be loaded from external systems) must have an ATP Category identifying the specific element. It is useful to differentiate planned elements - planned orders, etc from firm elements - sales orders, deliveries, production orders, etc. Usually (but not always) planned elements are managed (created/ modified) by APO but firm elements are not changed by APO planning.

SNP Planning books display this data by assigning ATP Category Groups (defined in transaction /SAPAPO/SNPCG) to Key Figures during Planning Area definition. Check definition of SAP delivered Planning Area such as 9ASNP02 to see how key figures are mapped to ATP Category Groups.

I would suggest getting your APO basics clarified by reading a introductory book like "Supply Chain Management with SAP APO"  By Jörg Thomas Dickersbach.
