For customers who have worked with Repetitive Manufacturing in the Releases before 4.0, the report, RMSERI_PLID1 for converting the planning ID1 to production lines is available.
You must use this report if you determined in Customizing that the planning ID1 is to be interpreted as the first aggregation field.
In Release 4.0, the system always interprets the production line
as the first aggregation element of the production version.
Therefore, you must create a work center (production line) for the
planning IDs that were previously used as the first aggregation
This report is used to generate these work centers. After the conversion to production lines, the list is issued with the newly created work centers. The planning IDs are retained and can still be used as planning ID 2.
