The Assembly window displayed BOM-list information and the configuration of the assembly:
The depiction of the ERP functionality (status lights) is by default adapted from the characteristic attribute table.
It immediately becomes obvious, if the subassemblies/parts of the assembly have ERP/PDM numbers and/or, whether a number can be assigned or not.
More detailed information can be found under Section 4.17.7, “ ERP for single parts in assembly tables / plinkcommon.cfg -> Block [PARTdataManager] -> Key "UseErpForAssPart" ” in PARTsolutions - Administration Manual.
The following image shows a complex assembly with subassemblies. No ERP/DPM number has been assigned to the highest assembly yet (red status light in the characteristic attribute table). Some single parts have already been assigned ERP/PDM numbers (green status light in the "assembly" window).
