Good morning all,
I have a question regarding the ReqPo table (planned order table).
We have two plans, but only use one (Master):

Last few days I checked the ReqPO table, and all planned purchase orders were planned with the planversion 'Master'.
This morning however, I saw a lot of new planned purchase orders in the table. However: not in the form. I checked the ReqPo table, and saw that in fact two Plan Versions were used (two different RecIds). So I checked the ReqPlanVersion table to see why, and I found out that this table contains Two versions of the 'Master' plan, with different recids:

In the Master planning menu I found the menu item 'Plan version cleanup'. When I run this, it removes one of the two Master planning records in the ReqPlanVersion:

The one that is left matches the RecId in the ReqPo Table )PlanVersion) and contains the records that are shown in the ReqPo form.
I do not understand however what triggers the new version of plan 'Master'. Is there someone who knows this? I would like to understand what planversion to use in my analytics.
Thanks for your explaination and help.
Kind regards, Willem.
