CALL_FUNCTION_NOT_FOUND

All of a sudden, user transactions fail because a certain function module cannot be found anymore. However, a search for this function module in table TFDIR by means of SE16 shows that it still exists in the database. If we look into the table buffer (AL12 -> Menu Statistics -> Buffers -> Single Key Buffer-> Keys -> Show buffered keys (for table TFDIR)) we see that the entry with the failing function module is marked with an 'X' in column NotFound.

This indicates that at some point in time the process of loading this function module into the table buffer returned a "not found" although the respective row exists in the database.
