Full physical inventory using MSCM and multiple handheld devices

Legacy Contributor

We have 10 fairly large inventory locations, the largest is our main OR with more than 21,000 distinct items totaling more that 87,000 individual eachs.
We want to be able to count everything using a number of handhelds concurrently with MSCM cycle counting.
The only way we can think to accomplish this is to setup multiple selectid's in IC70 and then put one select id on each handheld and go count.
But we are unsure of the best way to break up the items to multiple selectid's.

Ideally we would have ALL the items on ALL the handhelds and then sum the extract from each into a single count and variance analysis.

We are looking for suggestions on the best way to count these large locations quickly and accurately using MSCM
