Dependency formula changing dates - Excel Gannt

Hi

 

When i add a dependency into column G, it will amend the start date in column H.

What i want to happen is:

  • If the 'End Date' in cell I13 is after the Ind.Start Date (cell E14), then i want the Start Date in cell H14 to change to one day after I13.
  • However, if the end date in cell I13 is before the Ind.Start Date in cell E14, then the start date in H14 should remain as the Ind Start Date H14 

Any ideas on how i need to amend

    Does this do what you want?

     

    =IF(ind_start_date="","",IF(d_id="",ind_start_date,MAX(ind_start_date,INDEX($I:$I,MATCH(d_id,$B:$B,0))+1)))
