There isn’t a development time chart for Fomapan 400 in Fomatol P because Fomatol P / Bromophen is a paper developer, not a film developer. Paper and film developers are formulated differently and generally are not interchangeable for normal use.

So for Fomapan 400, you should use a proper film developer instead. Then check the film manufacturer’s datasheet or a trusted development chart for times.

You may be confusing Fomatol P with Fomadon P. If you meant Fomadon P, the correct times should be listed in Foma’s documentation or in resources like the Massive Dev Chart. But for Fomatol P, the answer is simply: it is not suitable for developing your film.
