Please see below a solution proposal how this request can be achieved with todays environment in EWM:
Excluding stock with allocated deliveries i.e. document category PDO, PDI, … form the warehouse monitor node Available Stock you can achieve already today:
➢ create a layout variant filtering out those document categories as shown on the following screenshots
By doing so all stock allocated to document category PDI, PDO, … will be filtered out.
And then create a variant monitor node for “Available Stock”, And then create a variant monitor node for “Available Stock”.
As result you have a variant monitor node that displays “Available Stock” w/o stock allocated to deliveries (i.e. document category PDO, PDI).
