Learn Turkish: Müşterinin herhangi bir yeni talebi yok. - The customer does not have any new request.

While hiç is often used for "any" in negative sentences (like hiç param yok - I don't have any money), herhangi bir emphasizes "any whatsoever" or "any specific one" among possibilities. Both are natural, but herhangi bir sounds a bit more formal or specific, emphasizing that there is not even a single new request of any kind.

Why is it müşterinin ... talebi and not just müşteri ... talep?

This is a great refresher on the Turkish way to express "to have" or "not to have". It uses the "owner + owned" structure. Müşteri gets the genitive suffix -nin to show the owner, and talep gets the possessive suffix -i to show the owned object. Combined with yok, the sentence literally translates to "The customer's ... request does not exist."

Why does the word talep change to talebi?

The base word for "request" is talep. When we add the vowel suffix -i (the possessive ending to show it belongs to the customer), the hard consonant p at the end softens to b. This is a standard Turkish pronunciation rule where the letters p, ç, t, and k soften to b, c, d, and ğ when followed by a vowel.
