User

I don't know if this request is possible or not...

Nice to hear that.

Excelchat Expert
10/08/2018 - 01:15

I manage a large spreadsheet set up in a table an dlots of data feeds into it via lookups, etc.

Excelchat Expert
10/08/2018 - 01:15

Ok.

User
10/08/2018 - 01:15

There are several columns where people make manual updates.

User
10/08/2018 - 01:16

This is a list of projects that we are tracking on the spreadsheet.

Excelchat Expert
10/08/2018 - 01:16

Ok

Excelchat Expert
10/08/2018 - 01:17

Please tell me further.

User

I was asked on one of the columns (a manual entry column) to do a formula where the field defaults to "No" until the person goes in an enters a date in the cell.

User
10/08/2018 - 01:18

so the cell has to have the MM/DD/YYYY format

User
10/08/2018 - 01:18

so the only thing that can be typed in that field is a date. Yet the cell is to default to "no" automatically first, until a date is entered.

Excelchat Expert
10/08/2018 - 01:19

so basically we are looking for a column to show No as default until the date is entered in the format MM/DD/YYY

User
10/08/2018 - 01:19

correct

User
10/08/2018 - 01:20

it's a column for project managers and they will see a big fat NO in this column which is for an important milestone, until they update it with a completion date.

Excelchat Expert
10/08/2018 - 01:20

Ok.

Excelchat Expert
10/08/2018 - 01:22

Please allow me to check few things.

User
10/08/2018 - 01:23

ugh so this makes it more complicated...there is already a formula in the field. I misspoke earlier when I said it was a manual field. Should I send you file with the formula?

Excelchat Expert
10/08/2018 - 01:23

Yes, that would help

Excelchat Expert
10/08/2018 - 01:23

Please share the file so that I can relate with it.

User
10/08/2018 - 01:23

sorry, just give me a sec and I will send.

Excelchat Expert
10/08/2018 - 01:24

Ok.

Excelchat Expert
10/08/2018 - 01:24

There is a way around

Excelchat Expert
10/08/2018 - 01:24

if you want to hear this.

User
10/08/2018 - 01:24

okay

Excelchat Expert
10/08/2018 - 01:25

we can keep the cell colored using conditional formatting until data is manually entered or until we have the desired result of the formula.

Excelchat Expert
10/08/2018 - 01:26

But please share the file, looking at formula, I might able to do something as per your requirement as this is working through formula.

User
10/08/2018 - 01:26

my sorry I had to strip some data. Just about done.

Excelchat Expert
10/08/2018 - 01:26

No problem. Please take your time.

User
10/08/2018 - 01:29

I think this is going to be too confusing. shoot.

User
10/08/2018 - 01:29

I need more time to prepare a dummy file. Here is something I did real quick

Excelchat Expert
10/08/2018 - 01:29

Ok. Please send it across.

User
10/08/2018 - 01:29

but there are tons of tabs this spreadsheet feeds from which all I am giving you is a copy of the final tab.

Excelchat Expert
10/08/2018 - 01:30

Ok.

User
10/08/2018 - 01:30

the column I am needing this functionality on is column W

[Uploaded an Excel file]

User
10/08/2018 - 01:30

the current formula in column W is :

User
10/08/2018 - 01:30

=IFERROR(IF(INDEX('Daniel PDS'!Y:Y,MATCH($A2,'Daniel PDS'!J:J,0))="","",INDEX('Daniel PDS'!Y:Y,MATCH($A2,'Daniel PDS'!J:J,0))),"")

Excelchat Expert
10/08/2018 - 01:31

Let me open the file

User
10/08/2018 - 01:31

of which the tab Daniel PDS is not included in what I sent you

User
10/08/2018 - 01:31

you're a genius if you can figure this all out! lol

Excelchat Expert
10/08/2018 - 01:31

Ok. allow me a minute

User
10/08/2018 - 01:32

of course

Excelchat Expert
10/08/2018 - 01:32

so these dates are populated using the above formula

User
10/08/2018 - 01:33

yes so the sequence would be ....populate column with the date from that formula if there is one available

User
10/08/2018 - 01:33

if not, populate with NO

Excelchat Expert
10/08/2018 - 01:33

Ok.

User
10/08/2018 - 01:33

Lastly, the person should be able to go in and replace NO with a date.

Excelchat Expert
10/08/2018 - 01:33

Manually?

Excelchat Expert
10/08/2018 - 01:34

replacing No manually means - deleting the formula.

Excelchat Expert
10/08/2018 - 01:35

=IFERROR(IF(INDEX('Daniel PDS'!Y:Y,MATCH($A2,'Daniel PDS'!J:J,0))="","No",INDEX('Daniel PDS'!Y:Y,MATCH($A2,'Daniel PDS'!J:J,0))),"No")

Excelchat Expert
10/08/2018 - 01:35

use this formula, it will give you a "No", if date is not found in Column J on Daniel PDS.

User
10/08/2018 - 01:37

maybe I was making it too complicated. okay, then I guess I set the format to date so they can only enter in the cell with a date format?

User
10/08/2018 - 01:38

or can I do some Data Validation ?

Excelchat Expert
10/08/2018 - 01:38

You can do Data Validation

Excelchat Expert
10/08/2018 - 01:38

this will not allow user to enter anything else other than date

Excelchat Expert
10/08/2018 - 01:38

and you can set the date format

User
10/08/2018 - 01:40

okay I didn't know if I could do the date format data validation considering there are "no's" in some cells.

User
10/08/2018 - 01:40

okay

Excelchat Expert
10/08/2018 - 01:40

Go to data validation, in the Allow section - Select - date then in the Data section: choose as per your requirement like greater than or less than or between,

User
10/08/2018 - 01:41

I gives me the green triangle errors....

Excelchat Expert
10/08/2018 - 01:41

You enter the formula first and then do the data validation

User
10/08/2018 - 01:41

but I guess I just select "ignore errors"?

Excelchat Expert
10/08/2018 - 01:41

Yes, if everything is working fine, you can ignore errors.

User
10/08/2018 - 01:42

okay thank you very much.

Excelchat Expert
10/08/2018 - 01:42

I hope, I could help as much as I can with the limited information I have.

User

yes it was great.thanks!
