Hello,
I am quite new to S.A.P & I have got a requirment where under a general assortment multiple assortment users (Stores in my case) is assigned and the stores can have different validity period (Can overlap aswell) during which the assortment can be procured and sold in the store and the same assortment can be displayed in multiple shelves in a store which has it's own validatiy periods, this is currently maintianed in the table E1BPE1WRSZ and supports only one valdity period. I am having challanges in updating the validity period when it gets changed through an external interface. I can think of maintaining the validity period using a "key"/"unique Identifier" from the external interface using which any updates can be made to that period once created for the first time (Eg., Changed from 1st Dec 2014 to 1st Jan 2015). The question is where can this key be held in this table ? Or do you think maintaining different validity period will be a problem (eg., during listing) ? or any better solution from S.A.P perspective will be helpful ? Please Advise.
