# Assign Cycle Dates (INV.P1)
Read Time: 1 minute(s)
The INV.P1 procedure is used to assign cycle dates to the inventory records. Inventory records are sorted by ABC code and assigned dates based upon the start date entered, the number of days between counts entered in the INV.CONTROL record and the work days specified in the MC.CONTROL record.
Frequency of Use
This procedure should be run when first setting up the system, after all parts have been entered into the system. It can be re-run at any time, with all cycle dates for the specified plan group being reset based upon the then- current data.
