PLS-00214

Error: PLS-00214: BEGIN...END block nesting is too deep

Causa: The number of levels of nesting in the PL/SQL block is too large. Blocks can be nested up to 255 levels deep, depending on the availability of system resources such as memory.

Acción: Reorganize the block structure to avoid nesting at too deep a level. For example, move the lowest-level sub-block to a higher level.
