HelloI prepare my schedule on primavera p6... it has 3 wbs levels. All activities in same wbs level has their own IDs (for example superstructural works' ID = SP1000, SP1010, SP1020 in p6 schedule, and finishing works' ID= FNS1000, FNS1010,FNS1020 ...etc.)... and All acitivities has different names... but when I export (File>Export>Export Format (spreadsheet)>...) to excel spreadsheet, some activities are not in order as in primavera schudle (for example, FNS100 and right after I see SP1000 ...and more over WBS order is different also, in p6 wbs order is like that fizibility, excavation, super structure, finishing works, elekctrical works, mekanical works ...but in exported excel spread sheet the order is different even though the activities under wbs is in order)... I am using to export (rather than coppy and paste) because I want to change some information on excel, then I will import to P6 (to make easier the process) but when activities and wbs is not in order as in p6, the process gets more difficult.. Thanks for your answer !
