Specific Text allow

[Sirfyaad]

How can allow entry below both bold texts.

AND(or(
startswith([PUTWAY NO],"PUT"),
startswith([PUTWAY NO],"FBF SMART"),
startswith([PUTWAY NO],"ADJUST_DONE")
),LEN([PUTWAY NO]) =8

Your logic is broken. You cannot enforce an 8-character field length and at the same time be looking for fields that start with a pattern of 8+ characters.

Give me suggestion

How can I do that. 

[Joseph_Seddik]

Already told you. YOUR logic is broken.

You want to allow a word that begins with an 11-Character pattern. AND at the same time you want to allow only words with a length of 8 characters. 

You want to allow animals that are larger than a cow and are of the same size exactly as a dog.

I don't know how you can do that.

[Sirfyaad]

I know this too.
