You may be looking at your reserves/commitments in your Funds Management (FM) reports and notice that they are lower then they were prior to the running of the annual Goods Receipt (GR)/Invoice Receipt (IR) clearing program in March.
In situations where a Purchase Order had a Goods Receipt processed against it but no Invoice Receipt, the annual GR/IR clearing program will nullify the existing Goods Receipt entry by posting an offsetting 48-series document and will release the reserve/commitment.
