Need function to auto update current date in A1 cell if i entered data in B1/C1/D1

you can use a circular function to date stamp

and so you need to check the content of B1,C1, D1

so
IF(AND(B1<>"", C1<>"", D1<>"") ,

change the options for circular reference and
Type the following formula into A1
=IF(AND(B1<>"", C1<>"", D1<>"") ,IF(A1="",NOW(),A1),"")

In A1

=if(COUNTA(b1:d1)>0,Now(),"")

Giri.hb,

Your post does not comply with Rule 8 of our Forum RULES. Do not crosspost your question on multiple forums without including links here to the other threads on other forums.

Cross-posting is when you post the same question in other forums on the web. The last thing you want to do is waste people's time working on an issue you have already resolved elsewhere. We prefer that you not cross-post at all, but if you do (and it's unlikely to go unnoticed), you MUST provide a link (copy the url from the address bar in your browser) to the cross-post.

Expect cross-posted questions without a link to be closed and a message will be posted by the moderator explaining why. We are here to help so help us to help you!

Read this to understand why we ask you to do this, and then please edit your first post to include links to any and all cross-posts in any other forums (not just this site).
