Deleting Early Start Constraints

A lot easier to just the functions already provided by P3.



In Glaobal Change, enter in the Then section



SNE EQ " ", this will remove all early start constraints,



SNL for late start and so on.

For the import/export, find here after the structure of an excel file:

ACT ECON ECOND LCON LCOND CON COND

AAAAAB2001 MS 07/07/2004

It is not easy to read the first time.

ECON mean early constrain type

ECOND used to insert the early date to constrain

LCON mean late constrain type

LCOND used to insert the late date to constrain

CON other date constrain, like expected and mandatory

COND used to insert the data



Then

ES/LS: Ealry/late start

EF/LF: Early/late finish

XF: expected finish

ON: start on

ZF: zero float

MF: must finish on

MS: must start on

and so on.

Not sure it can be done in global change. Quick fix if you have a lot of constraints is to export act ID and constraints data to excel and manually delete the records in excel then import back into P3.

Make a copy of project 1st, no undo with import/export.
